If Statement

The if statement is a foundational building block of control flow in most programming languages. It allows a program to make decisions and execute different blocks of code based on whether a given condition is true or false. The idea behind if statements is simple: If a condition is met, do something, otherwise, don’t.


              1234
            
if (condition)
{
    // Code to be executed if the condition is true
}

A condition is a boolean expression that evaluates to either true or false. If it is true, the code within the curly braces { } is executed; otherwise, if the condition is false, the code inside the block is skipped, and the program continues with the next statement following the if block.

main


              123456789101112
            
#include <iostream>

int main() 
{
    int age = 33; // Declaring and initializing a variable
    
    if (age >= 18) // Checking whether the age is greater or equal to 18
    {
		// If so, output the message
        std::cout << "You are an adult" << std::endl;
    }
}

If you have an if statement with only one statement to be executed when the condition is true, you can omit the curly braces { }.

Check if a two dimensional square with x (length) and y (height) can fit into another square with dimensions x1 (length) and y1 (height).
Output Can fit in console if it can.
