C++ Program to Swap Two Numbers
This example contains two different techniques to swap numbers in C programming. The first program uses temporary variable to swap numbers, whereas the second program doesn’t use temporary variables.
Programe :
#include <iostream>
using namespace std;
int main()
{
int a = 7, b = 10, temp;
cout << “Before swapping.” << endl;
cout << “a = ” << a << “, b = ” << b << endl;
temp = a;
a = b;
b = temp;
cout << “\nAfter swapping.” << endl;
cout << “a = ” << a << “, b = ” << b << endl;
return 0;
}
OutPut :
Before swapping.
a = 7, b = 10
After swapping.
a = 10, b = 7
