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);
}

Output

Temperature in Fahrenheit: 98.6
98.6F is 37.0C

Notes

* Changes shown in this solution:

Line 7: The temp_c variable is no longer needed, so it's removed.
Lines 10-11: the original call to the convert() function is removed
Line 11: The printf() statement is modified to contain the call to the convert() function as its final argument.

* Some compilers may warn of an unused variable if you forget to remove the declaration for the temp_c variable.
