Unit Convertor
over lst couple of days ive been working on a Unit Convertor. It converts Distances, Temperature, Volume and Wieght. I know it could be shorter by using my own functions thanks to coldDeath. #include <iostream>
#include <cstdlib>
using namespace std;
int main()
{
int selection, selection2, selection3, selection4, selection5, loop, loop2, loop3, loop4, loop5;
float c, f, k, temp, meas, meas2, meas3, dis, dis2, dis3;
loop = 1;
while (loop < 2){
cout << "~~~Welcome to the unit convertor~~~\n\n";
cout << "1. Temperature Convertor\n2. Metric and Imperial(Length)\n3. Metric and Imperial(Wieght)\n4. Metric and Imperial(Liquid Units)\n5. Exit\n\n";
cout << "Selcect an option(1,2,3,4,5): ";
cin >> selection;
if (selection == 1, 2, 3, 4, 5)
{
switch ( selection ) {
case 1:
system("cls");
loop2 = 1;
while (loop2 < 2){
cout << "~~~Welcome to the temperature convertor~~~\n\n";
cout << "1.Celsius\n2.Fahrenheit\n3.Kelvin\n4.Exit\n";
cout << "\nSelect starting measurment(1,2,3,4): ";
cin >> selection2;
if ( selection2 == 1, 2, 3, 4)
{
switch ( selection2 ) {

f = temp * 1.8 + 32;

}Tabbing looks mad on here. I didnt actual make the tabs that big |

First thing I noticed is how freakin' big your tabs are... in my opinion, it's very annoying

Egads, big tabs. I hope you copied and pasted to produce most of that code; it's very repetitive. Exactly why you should use functions.

Yea i did copy and paste, and for some reason the tabs seem much bigger when i copied the code into here

Yeah, they have got bigger than the one he sent me.
Try looking in your text editors options for something like "tab size" or "swap tabs for spaces"

What about.. file size units? I only used bytes, kilobytes, and megabytes, to ease the work on myself, but it could go up to yottabytes or down to bits.
 print "File size conversation tool\nType 'help' for help."
prompt = 'Enter a conversion such as "3 mb to kb" or "8 b to kb": '
def start():
line= raw_input(prompt).upper()
if 'HELP' in line:
print "Valid file size units:\nby (byte)\nkb (kilobyte)\nmb (megabyte)
print "\nExample conversions:\n3 mb to b\n3 kb to mb"
start()
t, fromto = None, []
for token in line.split(' '):
try:
t = float(token)
except ValueError:
pass
if token[:1] in 'MBKB':
fromto.append(token[0])
if t is None or len(fromto) != 2:
print 'Unsuccessful parse. Try again, using the format: 15 kb to b'
start()Yeah.. I'll let you finish that, because the last stretch of code has taken up enough of my time. x.x |

I would suggest setting up your editor so that it converts tabs to spaces -- far fewer spaces.
