Lecture 1:- Lets Start With First Code

Let's write a simple C++ program that takes two numbers as input and prints their sum. This is the equivalent of the previous Python program but in C++.

cpp

#include <iostream> using namespace std; int main() { // Declare variables to store the input numbers and the result int a, b, result; // Read two integers from input cin >> a >> b; // Calculate the sum of the two numbers result = a + b; // Print the result cout << result << endl; return 0; }

Explanation:

We include the <iostream> header to use input and output operations in C++.

In the main() function, we declare three integer variables: a, b, and result.

We use cin to read two integers from the user, storing them in variables a and b.

We calculate the sum of a and b and store it in the variable result.

Finally, we use cout to print the value of result as the output. The << endl is used to move to the next line after printing the result.

When you run this C++ program and input two integers, it will display their sum as the output, just like the Python program.

For example, if you input:

3 5

The program will output:

8

Remember to compile and run the C++ program using a C++ compiler such as g++ or Visual Studio C++ compiler. Happy coding! If you have any more questions or need further assistance, feel free to ask.
