Solution for Exercise 10-10

ex1010

#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)
{
    float t;

    t = (f - 32) / 1.8;
    return(t);
}

Notes

* The "other change" mentioned in the book is the removal of the temp_c variable, which is no longer needed. It had to be removed at Line 7 (not declared) and from Lines 11 and 12 in the original code.

* The compiler may warn you when unused variables exists in your code.
