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);
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;
}
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:

Will someone be able to tell me where I went wrong and help me sort it out? Thankyou
