What are the parameters of a for loop statement in C++?

In C++, the for loop statement takes three parameters: the initial value of the loop variable, the loop condition, and the update of the loop variable. The specific form is as follows:

for (initial value; loop condition; update) {
// loop body
}

The initial value is used to initialize the loop variable, and is executed once before the first iteration. The loop condition is a boolean expression that determines whether the loop continues to execute. If the loop condition is true, the loop body is executed; if the loop condition is false, the loop is exited. Updating is used to update the value of the loop variable, and is executed once after each iteration.

Furthermore, in a for loop statement, you can omit any of its parameters, but the semicolons must be retained. For instance, you can omit the initial value and the update, and only keep the loop condition.
