my assignment is to write a program that asks for a temperature in celcius, then spits out a value in fahrenheit, kelvin and reaumur.

This is what i have done:

#include <stdio.h>
#include <stdlib.h>

int main()
{
    float Temp;
    float Fahr, Kelvin, Reamur;

    printf(" Celcius >> ");
    scanf("%f", &Temp);

    Fahr = (Temp * 9/5) + 32;
    Reamur = Temp * 0.8;
    Kelvin = Temp + 273 ;
    printf("\n Fahrenheit >> %f\n", Fahr);
    printf("\n Reamur >> %f\n", Reamur);
    printf("\n Kelvin >> %f\n", Kelvin);

    printf("\n\n\n");
    system("pause");
    return 0;
  }

Now the lecture want me to rewrite the code using either " ?: ". i'm not sure how this ?: actually works. Could someone please explain to me ??

Thx in advanced

Well you would have needed to use if / else to make sense of using ?:

if ( a < b ) x = 1; else x = 2;

x = a < b ? 1 : 2;

?: is OK for small conditions, IMO, but NEVER nest it! It's the most ugly thing to dubug!!

It's not any harder to debug than an if-else ladder. Just use whitespace like you would with with your if-else tree. Your code is only as ugly as you make it.
