# C++ Loops

Loops are used in programming to perform repetitive tasks or execute a block of code multiple times. They are essential for automating processes and handling situations where you need to repeat a specific action under certain conditions. There are two primary types of loops in most programming languages:

1. **For Loops:** These loops are typically used when you know in advance how many times you want to repeat a specific block of code. They consist of three parts: initialization, condition, and increment/decrement. The loop continues to execute as long as the condition is true.
    
    **Syntax:**

    Statement 1 - where we need to do initilization.
    
    Statement 2 - where we need to do condition
    
    Statement 3 - where we need to be increment or decrement.

2. **While Loops:** These loops are used when you want to execute a block of code repeatedly until a certain condition becomes false. "while" loops can run indefinitely if the condition never becomes false.
    
    **Syntax:**

3. **Do- while:** The `do-while` loop is similar to the `while` loop, but the condition is checked after the loop body is executed, so the loop is guaranteed to run at least once.
