Day 3 of Learning C++: Mastering Control Flow

Greetings, fellow learners! It's Day 3 of our C++ adventure, and today, we're diving into the world of control flow. These concepts are the building blocks of decision-making and looping in your C++ programs.

Conditional Statements: Making Choices

Conditional statements allow your program to make decisions. The most basic one is the if statement. Here's a simple example:

#include <iostream>

int main() {
    int age;
    std::cout << "Enter your age: ";
    std::cin >> age;
    if (age >= 18) {
        std::cout << "You are an adult." << std::endl;
    } else {
        std::cout << "You are a minor." << std::endl;
    }
    return 0;
}        

In this code, we check if age is greater than or equal to 18. Depending on the result, different messages are displayed.

Loops: Repeating Actions

Loops are used to execute a block of code repeatedly. C++ provides several types of loops, but let's focus on the for loop for now. Here's an example that prints numbers from 1 to 5:

#include <iostream>

int main() {

    for (int i = 1; i <= 5; i++) {
        std::cout << i << " ";
 }

 std::cout << std::endl;
 return 0;
}        

In this code, the for loop initializes a counter i to 1 and repeats the code block until i is less than or equal to 5. Each time the loop iterates, i is incremented by 1.

Key Takeaways for Day 3:

Conditional statements (if, else, else if) enable your program to make decisions based on conditions.

Loops (for, while, do-while) allow you to repeat actions, making your code more efficient and flexible.

Next Steps:

For Day 4, let's delve into functions. Functions are essential for breaking your code into smaller, reusable parts. We'll learn how to define and call functions, passing data to them, and returning results.
