C++ For Loop

C++ For Loop

When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop.

Syntax

for (statement 1; statement 2; statement 3) {
  // code block to be executed
}

• Statement 1 is executed (one time) before the execution of the code block.
• Statement 2 defines the condition for executing the code block.
• Statement 3 is executed (every time) after the code block has been executed.

Example

for (int i = 0; i < 5; i++) {
  cout << i << "\n";
}

For loops are the best choice for iterating over arrays and strict counting tasks.
