When you know exactly how many times you want to loop through a block of code, use theforloop instead of awhileloop: Syntax for(statement 1;statement 2;statement 3) { // code block to be executed } Statement 1is executed (one time) before the execution of the code block. ...
for 循环允许您编写一个执行特定次数的循环的重复控制结构。语法C++ 中 for 循环的语法:for ( init; condition; increment ) { statement(s); } 下面是 for 循环的控制流:init 会首先被执行,且只会执行一次。这一步允许您声明并初始化任何循环控制变量。您也可以不在这里写任何语句,只要有一个分号出现即可。
