Meaning, the loop terminates if the statement expression/ condition becomes false. This structure allows programmers to control the flow of their code and perform repetitive tasks with ease. Syntax Of For Loop In C++ for (initialization; condition; increment/decrement) {// code to be executed} ...
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。 接下来,会判...

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. ...
