The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
A while statement causes the statement (also called the loop body) to be executed repeatedly until the expression (also called controlling expression) compares equal to zero. The repetition occurs regardless of whether the loop body is entered normally or by a goto into the middle of statement....
Regardless of whetherstatementis a compound statement, it always introduces ablock scope. Variables declared in it are only visible in the loop body, in other words, while(--x>=0)inti;// i goes out of scope is the same as while(--x>=0){inti;}// i goes out of scope ...
In this C++ tutorial, you will learn the syntax of While loop statement, its algorithm, flowchart, then some examples illustrating the usage of it. Later in the tutorial, we shall go through Infinite While Loop and Nested While Loop. C++ While Loop While Loop can execute a block of stateme...
A while loop in C++ is an example of an entry-controlled loop wherein the condition is checked at the entry of the loop. The loop runs until the condition is true, and the statements/ block of code inside the body of the loop are executed. The loop terminates as soon as the ...
simple.cpp #include <iostream> int main() { int i = 0; int sum = 0; while (i <= 10) { sum += i; i++; } std::cout << sum << std::endl; return 0; } We calculate the sum of 1..10 numbers. The while loop has three parts: initialization, testing and updating. Each ...
Edit & run on cpp.sh In line 13 it says "recedent", but the while loop is going in the opposite direction. It is a minor thing, but something to consider. Some other minor points: intmain() {. Although it makes no difference to the compiler this is the way I most often see it...
while loop do...while loop In the previous tutorial, we learned about the C++ for loop. Here, we are going to learn about while and do...while loops. C++ while Loop The syntax of the while loop is: while (condition) { // body of the loop } Here, A while loop evaluates the con...
Edit & run on cpp.sh Nov 27, 2019 at 12:58am deleted account xyzzy(5768) Which "while" loop isn't repeating? You have 1 "do-while" loop, lines 8 - 53, and two "while" loops, lines 16-20 and lines 27-49. (Your indentation formatting needs a bit of work) ...
C++ while 循环 C++ 循环 只要给定的条件为真,while 循环语句会重复执行一个目标语句。 语法 C++ 中 while 循环的语法: while(condition) { statement(s); } 在这里,statement(s) 可以是一个单独的语句,也可以是几个语句组成的代码块。condition 可以是任意的
