C programming Question 2.5

Exercise 2.5. Write a function that computes the minimum and the maximum imum of two integer variables and returns them through call-by-reference parameters. It should have the following prototype:

lint minmax(int a, int b, int * min, int * max);

Write a unit test of minmax in a main function.

The code I wrote

#include #include

int minmax(int a, int b, int *min, int * max){ assert(min != NULL); if(min == NULL || max == NULL){ return -1;} if (a>b) return 0 ; else (b>a) return 0; } int main(void){ int t =minmax(3,5, NULL, NULL) m =3; r =5; int x, y int err = minmax(m, r, &x, &y); assert(err == 0 && x==3 && y==5); err = minmax(r, m, &x, &y);}
