The Program in C++ to Swap two numbers is given below:
#include <iostream>
using namespace std;
int main() {
int num1, num2, temp;
cout << "Enter the first number: ";
cin >> num1;
cout << "Enter the second number: ";
cin >> num2;
//swapping using temporary variable
temp = num1;
num1 = num2;
num2 = temp;
cout << "The first number after swapping: " << num1 << endl;
cout << "The second number after swapping: " << num2 << endl;
return 0;
}
Output:
Enter the first number: 56
Enter the second number: 23
The first number after swapping: 23
The second number after swapping: 56
Pro-Tips💡
This C++ program is used to swap the values of two numbers.
The program starts by including the input/output stream library and using the standard namespace.
Then, it declares two integer variables ‘num1‘ and ‘num2' and a temporary variable ‘temp'.
The program then prompts the user to enter two numbers, which are stored in the variables ‘num1' and ‘num2'.
Next, the program uses the temporary variable ‘temp' to swap the values of ‘num1' and ‘num2'. It does this by first storing the value of ‘num1' in ‘temp', then assigning the value of ‘num2‘ to ‘num1‘, and finally, assigning the value stored in ‘temp' to ‘num2'.
Finally, the program prints the values of 'num1' and ‘num2' after swapping, and the program ends.
