 challenge.h 

#include <stdio.h>

float foo(float F); 

float bar(float F);

main.c 

#include "challenge.h"

float a = 8.5;

int main() {

 float fa = foo(a);

 float ba = bar(a);

 printf(“%.1f\n”, fa + ba);

 return 0;

}

challenge.c

#include "challenge.h"

extern float a;

float foo(float F) {

 a = 7.3;

 return F * a

}

challenge2.c

#include "challenge.h"

extern float a;

float bar(float F) {

 a = 7.5;

 float ff = foo(F);

 return ff * a;

}
