Swapping numbers in C++ means exchanging the values of two C++ variables with each other.
C++ program to Swap two numbers using third variables.
#include <iostream> using namespace std; int main() { int a,b,c; cout << "Enter value of a: "; cin >> a; cout << "Enter value of b: "; cin >> b; c=a; a=b; b=c; cout<<"After swaping a: "<< a << " b: " << b; return 0; } /* OUTPUT: Enter value of a: 5 Enter value of b: 3 After swaping a: 3 b: 5 */
C++ program to Swap two numbers without using third variable
#include <iostream> using namespace std; int main() { int a,b; cout<<"Enter value of a: "; cin>>a; cout<<"Enter value of b: "; cin>>b; a=a+b; b=a-b; a=a-b; cout<<"After swaping a: "<<a<<"b: "<<b; return 0; } /* OUTPUT: Enter value of a: 5 Enter value of b: 3 After swaping a: 3 b: 5 */
