Question

 Write a function in C++ to accept four integers. Find the smallest integer and print it.

Answer 1

 # include <iostream.h>
void main ( )
{
int a, b, c, d, small ;
int min (int, int, int, int); //Prototype
cout << “Enter the four number :” <<endl;
cin >> a >> b >> c >> d;
small = min (a, b, c, d); //function call
cout << “The smallest number is :” <<small;
}
// function definition
int min (int n1, int n2, int n3, int n4)
}
int low;
if (n1 < n2)
low = n1;
else
low = n2;
if (n3 < low)
low = n3;
if (n4 < low)
low = n4;
return (low);
