We have already learned about the while loop and its structure, but it may not always be the most convenient choice when we need to repeat a block of code a specific number of times.

With a while loop, we typically need to declare and initialize a counter variable, define a condition, and remember to increment the counter within the loop body.

For Loop

In C++, there is an alternative control flow structure called the for loop, which offers a more concise and structured approach to repetitive code execution. Both the for and while loops serve the purpose of repeating code, but they are designed for different scenarios and have unique advantages.

• Initialization: This is where you typically initialize a loop control variable (e.g., int i = 0), which sets the initial state of the loop;
• Condition: The loop continues as long as this condition is true (e.g., i < 5);
• Update: After each iteration, the update statement is executed (e.g., i++ to increment i by 1).

A while loop typically consumes more code space and is often considered less intuitive to read. A for loop essentially contains the same elements as a while loop but offers a more convenient and concise way to work with them.
