1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

#include<iostream> using namespace std; void zero_small(int &,int &); int main() { int x,y; cout<<"Enter first number : "; cin>>x; cout<<"Enter second number : "; cin>>y; zero_small(x,y); cout<<"First number is : "<<x; cout<<"\nSecond number is : "<<y; return 0; } void zero_small(int &a, int &b) { if(a<b) a=0; else b=0; }

SAMPLE RUN # 1

Enter first number : 23
Enter second number : 6
First number is : 23
Second number is : 0

SAMPLE RUN # 2

Enter first number : 23
Enter second number : 56
First number is : 0
Second number is : 56
