for loop while loop do while loop for loop in C A for loop is a control structure that enables a set of instructions to get executed for a specified number of iterations. It is an entry-controlled loop. for loop FlowchartSyntax for(initialization; test condition; update expression){ //code...
Do While Loop in C A do while loop is a type of loop that runs a set of instructions until a specified condition is met. The do while loop is similar to the while loop, except that the do while loop will always run the code at least once before checking the condition. ...
we exit the loop and if it istrue, we enter the loop. After entering the loop, we execute the statements inside thewhileloop, update the iterator and then again check the condition. We do the same thing unless the condition isfalse. ...
2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true or false but this is not the case with while. While loop is executed only when the condition is true. Syntax: do{ //code }while...
While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a specific condition is true. What Is A For Loop In C++? A for loop in C++ language...

为了发挥其强大的操控能力,程序需要有执行重复的操作和进行决策的工具。当然,C++提供了这样的工具。事实上,它使用与常规C语言相同的 for循环、while循环、do while循环、if 语句和switch语句。这些程序控制语句通常都使用关系表达式和逻辑表达式来控制其行为。
事实上,它使用与常规C语言相同的 for循环、while循环、do while循环、if 语句和switch语句。这些程序控制语句通常都使用关系表达式和逻辑表达式来控制其行为。 for循环 很多情况下都需要程序执行重复的任务,如将数组中的元素累加起来或将歌颂生产的赞歌打印20份,C++中的 for循环可以轻松地完成这种任务。我们来看看下面...
