If Statements and Loops in C++ 🚦🔄
Hello, Code Navigators!
Today, we're setting sail into the exciting waters of control structures in C++. But before we embark on this coding adventure, let's take a moment to appreciate the significance of C++, a quick journey through its history, and understand why mastering control structures is like having a compass for your code.
C++: The Navigator's Language
C++ is more than a language; it's a guide through the vast landscape of programming. With roots in the '80s, Bjarne Stroustrup designed C++ to provide developers with tools to navigate and control the execution of their code efficiently.
A Brief Sojourn through Coding History ⏳
As we sail through the seas of code, let's remember that C++ wasn't born overnight. It evolved, adding features like control structures to empower programmers in their quest for creating powerful and dynamic applications.
Why Control Structures Matter?
Control structures, like if statements and loops, are the compass and map of your code. They determine how your program flows, allowing you to make decisions and repeat actions based on specific conditions.

Imagine Jordan, a coding navigator eager to steer through the intricacies of C++. Having mastered variables, Jordan is ready to command the ship using if statements and loops.
Navigating Control Structures: A Beginner's Guide
The Power of If Statements:
If statements allow you to make decisions in your code. For example:
cppif (x > 0) { // Do something if x is greater than 0 } else { // Do something else if x is not greater than 0 }
Looping into Action:
Loops let you repeat actions. The
for
loop is a classic example:cppfor (int i = 0; i < 5; ++i) { // Code inside the loop that repeats 5 times }
Enhancing Decision-Making with Switch Statements:
Switch statements provide a neat way to handle multiple cases:
cppswitch (day) { case 1: // Code for Monday break; case 2: // Code for Tuesday break; // ... other cases default: // Code if none of the cases match }
Jordan's Nautical Code Adventure 🚢🌊
Jordan decided to create a program that determines whether a given number is even or odd using an if statement:
cpp#include <iostream>
int main() {
int number;
std::cout << "Enter a number: ";
std::cin >> number;
if (number % 2 == 0) {
std::cout << "The number is even." << std::endl;
} else {
std::cout << "The number is odd." << std::endl;
}
return 0;
}
