Original:

The above syntax produces code equivalent to:

{ init_expression ; while ( cond_exression ) { loop_statement iteration_expression ; } }

init_expressionは、ループの実行前に実行されます。 cond_expressionはboolに変換、値に評価しなければならない。これは、ループの各反復の前に評価されます。ループは、その値がtrueある場合にのみ続行されます。 loop_statementはiteration_expressionが実行された後、繰り返しのたびに実行されます.

Original:

The init_expression is executed before the execution of the loop. The cond_expression shall evaluate to value, convertible to bool. It is evaluated before each iteration of the loop. The loop continues only if its value is true. The loop_statement is executed on each iteration, after which iteration_expression is executed.

#include <iostream>
 
int main() 
{
    for (int i = 0; i < 10; i++) {
        std::cout << i << " ";
    }
 
    std::cout << '\n';
 
    for (int j = 2; j < 9; j = j + 2) {
        std::cout << j << " ";
    }
}

Output:
