Solution for Exercise 10-11

ex1011

#include <stdio.h>

float convert(float f);

int main()
{
    float temp_f;

    printf("Temperature in Fahrenheit: ");
    scanf("%f",&temp_f);
    printf("%.1fF is %.1fC\n",temp_f,convert(temp_f));
    return(0);
}

float convert(float f)
{
    return(f - 32) / 1.8;
}

Output

Temperature in Fahrenheit: 212
212.0F is 100.0C

Notes

* You could put the entire equation from Line 17 in parentheses:

return((f - 32) / 1.8);

* Parentheses are optional in a return statement, required only if the evaluation needs them. I always use parentheses in my code, mostly from habit.
