Explanation: - #include <iostream>: Includes the input/output stream library for basic input and output operations. - using namespace std;: Declares that the program will use the standard namespace for shorthand access to standard library elements. - int main() {...}: The main function where the execution of the program begins. - int num1, num2, sum;: Declares three integer variables num1, num2, and sum. - cout << "Enter first number: ";: Outputs a message prompting the user to enter the first number. - cin >> num1;: Takes user input from the keyboard and assigns it to the variable num1. - cout << "Enter second number: ";: Outputs a message prompting the user to enter the second number. - cin >> num2;: Takes user input from the keyboard and assigns it to the variable num2. - sum = num1 + num2;: Calculates the sum of num1 and num2 and stores it in the variable sum. - cout << "Sum of " << num1 << " and " << num2 << " is: " << sum << endl;: Outputs the sum of num1 and num2 along with the numbers themselves. - return 0;: Indicates that the program executed successfully and returns 0 to the operating system.
