Question

Write a C – program that calls a user-defined function from within main() that determines the minimum value from three

positive numbers received from the user. Your function should be called minimum.  You must use a loop to receive the numbers.

If the user enters a negative number, you must ask the user to re-enter the number.

The function should also print out the positive numbers and the smallest number.

Answer 1

code:

#include<stdio.h>

int minimum(int a,int b,int c);

int main()

{

int i,array[100],a,b,c,d;

printf("enter the array elements:\n");

for(i=0;i<3;i++)

{

scanf("%d",&array[i]);

if(array[i]<0)

{

i--;

printf("please enter postive number: ");

}

}

a=array[0];b=array[1];c=array[2];

printf("positive numbers :%d %d %d\n",a,b,c);

d=minimum(a,b,c);

printf("minimum number: %d ",d);

}

int minimum(int a,int b,int c)

{

if(a<b && a<c)

return a;

else if(b<a && b<c)

return b;

else

return c;

}
