C# Pilot Program
Hey guys, I've posted this somewhere on the site before but I thought I'd post it here. I'm making a little program of my own for pilots (mainly for getting my practice on the code) so here it goes:
/* Aviation program for Pilots
Created by Harry Wheildon */
using System;
class Avi {
public static void Main() {
char choice;
char std;
double speed;
double distance;
double time;
// Insert future variables here
for(;;) {
do {
Console.WriteLine("Choose one from the list:\n");
Console.WriteLine("1. Speed; Distance; Time");
Console.WriteLine("2. ISA Deviation");
Console.WriteLine("3. Time to Impact");
Console.WriteLine("4. Track Error; Closing Angle\n");
Console.Write("Choose one (press Q to quit): ");
do {
choice = (char) Console.Read();
} while(choice == '\n' | choice == '\r');
} while( choice < '1' | choice > '4' & choice != 'q');
if(choice == 'q') break;
Console.WriteLine("\n");
switch(choice) {
case '1':
Console.WriteLine("Here you can calculate the Speed, Distance or Time")
Console.WriteLine("Choose which one you want to calculate:")
Console.WriteLine("1. Speed")
Console.WriteLine("2. Distance")
Console.WriteLine("3. Time\n")
Console.Write("Choose one (press B to go back): ");
do {
std = (char) Console.Read();
} while(choice == '\n' | choice == '\r');
} while( choice < '1' | choice > '3' & choice != 'b');
if(choice == 'b') break;
Console.WriteLine("\n");
switch(std) {
case '1':
Console.Write("Distance: ");
distance = (double) Console.Read();
Console.Write("Time: ");
time = (double) Console.Read();
speed = distance / time;
Console.WriteLine("Your Distance was: " + distance);
Console.WriteLine("Your Time was: " + time);
Console.WriteLine("Thus your Speed is " + speed);
break;
case '2':
Console.Write("Speed: ");
speed = (double) Console.Read();
Console.Write("Time: ");
time = (double) Console.Read();
distance = speed * time;
Console.WriteLine("Your Speed was: " + speed);
Console.WriteLine("Your Time was: " + time);
Console.WriteLine("Thus your Distance is: " + distance);
break;
case '3':
Console.Write("Speed: ");
speed = (double) Console.Read();
Console.Write("Distance: ");
distance = (double) Console.Read();
time = distance / speed;
Console.WriteLine("Your Speed was: " + speed);
Console.WriteLine("Your Distance was: " + distance);
Console.WriteLine("Thus your Time is: " + time);
break;There it is, and I was just wondering, now that I've done a switch inside a switch, will it need to be inside a block (The second piece of code for the Speed, Distance and Time)? If it doesn't, then what will I do with that very end break to end the case '1' of the whole SDT, and the case '3' of the Speed calculation? Will I need to put: case '3':
Console.Write("Speed: ");
speed = (double) Console.Read();
Console.Write("Distance: ");
distance = (double) Console.Read();
time = distance / speed;
Console.WriteLine("Your Speed was: " + speed);
Console.WriteLine("Your Distance was: " + distance);
Console.WriteLine("Thus your Time is: " + time);
break;
break;Or will I of course use a block around the switch inside the switch? Thanks for reading, Haz |

Well I've completed it and I cmplied it, but there are some errors that I'm not exactly sure about, and everytime I try to correct them, it gets worse. Here's the code:
/* Aviation program for Pilots
Created by Harry Wheildon */
using System;
class Avi {
public static void Main() {
char choice;
char std;
double speed;
double distance;
double time;
int alt;
double tempx;
double x, y, z, a;
int ac1, ac2;
double vis;
double dt, dg, te, dtg, ca;
int degreesAdd (int n1, int n2)
{
return (n1 + n2) % 360;
}
for(;;) {
do {
Console.WriteLine("Choose one from the list:\n");
Console.WriteLine("1. Speed; Distance; Time");
Console.WriteLine("2. ISA Deviation");
Console.WriteLine("3. Time to Impact");
Console.WriteLine("4. Track Error; Closing Angle\n");
Console.Write("Choose one (press Q to quit): ");
do {
choice = (char) Console.Read();
} while(choice == '\n' | choice == '\r');
} while( choice < '1' | choice > '4' & choice != 'q' );
if(choice == 'q') break;
Console.WriteLine("\n");
switch(choice) {
case '1':
Console.WriteLine("Here you can calculate the Speed, Distance or Time\n")
Console.WriteLine("Choose which one you want to calculate:")
Console.WriteLine("1. Speed")
Console.WriteLine("2. Distance")
Console.WriteLine("3. Time\n")
Console.Write("Choose one (press B to go back): ");
do {
std = (char) Console.Read();
} while(choice == '\n' | choice == '\r');
} while( choice < '1' | choice > '3' & choice != 'b');
if(choice == 'b') break;
Console.WriteLine("\n");
switch(std) {
case '1':
Console.Write("Distance: ");
distance = (double) Console.Read();
Console.Write("Time: ");
time = (double) Console.Read();
speed = distance / time;
Console.WriteLine("Your Distance was: " + distance);
Console.WriteLine("Your Time was: " + time);
Console.WriteLine("Thus your Speed is " + speed);
Console.WriteLine("NOTE: Make sure the units are compatible with each other");
break;
case '2':
Console.Write("Speed: ");
speed = (double) Console.Read();
Console.Write("Time: ");
time = (double) Console.Read();
distance = speed * time;
Console.WriteLine("Your Speed was: " + speed);
Console.WriteLine("Your Time was: " + time);

break;
case '3':
Console.Write("Speed: ");
speed = (double) Console.Read();
Console.Write("Distance: ");
distance = (double) Console.Read();
time = distance / speed;
Console.WriteLine("Your Speed was: " + speed);
Console.WriteLine("Your Distance was: " + distance);
Console.WriteLine("Thus your Time is: " + time);
break;
}
case '2':
Console.WriteLine("Here you can calculate the ISA deviation\n");
Console.Write("Altitude: ");
alt = (int) Console.read();
Console.Write("Temp. at Alt.: ");
tempx = (double) Console.Read()
x = alt - 1000;
y = 2 * x;
z = 15 - x;
Console.WriteLine("This is the ISA temp. at that level: " + z);
a = tempx - z;
Console.WriteLine("This is the ISA Deviation: " + a);
break;
case '3':
Console.WriteLine("Here you can calculate the Time to Impact of 2 aircraft\n");
Console.Write("Speed of Aircraft 1: ");
ac1 = (int) Console.Read();
Console.Write("Speed of Aircraft 2: ");
ac2 = (int) Console.Read();
speed = ac1 + ac2;
Console.WriteLine("Your closing speed is: " + speed);
Console.WriteLine("Now the program will convert the in-flight visibility from Kilometres to Nautical Miles.");
Console.Write("In-flight vis. (km): ");
vis = (double) Console.Read();
x = ( vis * 1000 * 3.128 ) / (6076);
Console.WriteLine("Your in-flight vis. is: " + x "nm");
Console.WriteLine("Now the program will calculate the time to impact in hours");
y = x / speed;
Console.WriteLine("The Time to Impact is: " + y "hours\nNow it will convert it into seconds");
z = y * 3600;
Console.WriteLine("\nYour Time to Impact is: " + z "seconds");
break;
case '4':
Console.WriteLine("Here you can calculate the Track Error, Closing Angle, and the angle at which\n to travel to get to the destiniation");
Console.Write("Distance Off Track: ");
dt = (double) Console.Read();
Console.Write("Distance Gone ");
dg = (double) Console.Read();
x = (dt) / (dg);
y = x * 60;
Console.WriteLine("The Track Error is: " + y "degrees");
Console.WriteLine("Now the prgram will calculate the Closing Angle");
Console.Write("Distance to go: ");
dtg = (double) Console.Read();
z = (dt) / (dtg);
a = z * 60;
Console.WriteLine("The Closing Angle is: " + a "degrees");
Console.WriteLine("Now the program will figure out the directiong to fly to get to the destination");
z = addDegrees (a, y);
Console.WriteLine("The angle at which to travel to get to the destination is" + z "degrees");
break;
}
}
Console.WriteLine();
}
}And here's the output: AviProgram.cs(20,32): error CS1513: } expected

It's simple - you need a Main function. Stick public static int Main around the main program, and enclose it with curly braces.

Ahhh, instead of public static void Main()? THANKYOU :-D

Ah... didn't see that. In that case, move the degreesAdd function out of your Main function (but keep it in the class).

Yep, kind of worked, just ONE more error to sort out :-(.

There's a } where it shouldn't be, or one missing. I'm too lazy to find it, however - just scour your code until you find it.

I copy/pasted into dev, just to check for matching braces. It appears that last brace is not needed.

Hmmm I tried that but it turned out with dodgy errors. (Besides, that's the brace that connects to Class Avi { isn't it? I also ran through the program and it seems that all brace are fine.
I put the brace back in and it now only has 2 errors: Avi Program.cs(43,4): error CS0163 : Control cannot fall through from one case level ('case 49:') to another
Avi Program.cs(176,8): error CS0103: The name 'addDegrees' does not exist in the class or namespace 'Avi'EDIT: I've managed to sort out the first error, it turned out I needed to break the entire switch(std) as it was a nested switch. Now all I need to do is solve the 2nd error!  Help please!  Last edited by Haz; May 2nd, 2005 at 9:29 PM. |
