I am writing an easy code that takes two numbers I enter and tells me which is the Max value and which is the Min value using 2 separate files for functions. here is my code so far. It scans the number and has the correct Max Min but when I go to print the values a crazy number prints.
#include<stdio.h>
int main(void)
{
double num2, max, min, num1;
printf("enter any space-separated pair of decimal numeric values on the same line: ");
scanf("%le%le", &num1, &num2);
max = ComputeMaximum(num1, num2);
min = ComputeMinimum(num1, num2);
printf("%le", max);
printf("%le", min);
return 0;
}
this is my main program, on seperate files in the same project I have:
double ComputeMinimum(double num1, double num2) {
double result;
result = (num1 < num2) ? num1 : num2;
return result;
}
And
double ComputeMaximum(double num1, double num2) {
double result;
result = (num1 > num2) ? num1 : num2;
return result;
}
I would like to have it print to screen:
ComputeMinimum(?, ?) returned ?
ComputeMaximum(?, ?) returned ? (question marks are the values.)

Answer 1

Code is missing prototypes.
That is all, format is OK, functions are OK.
#include<stdio.h>
// Add these to the same file as main()
// Or better yet, add to another file Compute.h and #include "Compute.h"
// here and in the the separate C file
double ComputeMinimum(double num1, double num2);
double ComputeMaximum(double num1, double num2);
int main(void)
...
// suggest adding check
if (2 != scanf("%le%le", &num1, &num2)) {
puts("Input error");
return -1;
}
