Example int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while...
Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
whileLoopExample(); // 调用while循环示例函数 doWhileLoopExample(); // 调用do-while循环示例函数 return 0; // 程序结束，返回0表示正常退出 } // 使用for循环打印1到10的数字 void forLoopExample() { // for循环初始化变量i为1，循环条件是i小于等于10，每次循环后i增加1 for (int i = 1; i <...
Example 1: while loop // Print numbers from 1 to 5 #include <stdio.h> int main() { int i = 1; while (i <= 5) { printf("%d\n", i); ++i; } return 0; } Run Code Output 1 2 3 4 5 Here, we have initialized i to 1. When i = 1, the test expression i <= 5 ...
C do...while Loop: Example 1Input two integers and find their average using do while loop.#include <stdio.h> int main() { int a, b, avg, count ; count =1; do { printf("Enter values of a and b: "); scanf("%d %d",&a,&b); avg=(a+b)/2; printf("Average = %d" , ...
Example 2: Check for the Presence of the Digit 5 Using a Do-While Loop=begin Ruby program to check whether the given number contains the digit `5` using a do-while loop =end puts "Enter the number:" num = gets.chomp.to_i temp = num flag = false # Flag is a boolean variable ...
Statement: executes the do while loop. Loop: denotes the end statement of the do while loop; goes back to the initial stage to re-run the do while loop. Example 1 – Changing the Cell Color Based on Marks The sample dataset includes students’ names and marks. ...
Flowchart of C++ while loop Example 1: Display Numbers from 1 to 5 // C++ Program to print numbers from 1 to 5 #include <iostream> using namespace std; int main() { int i = 1; // while loop from 1 to 5 while (i <= 5) { cout << i << " "; ++i; } return 0; } ...
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...
1. while Loop in C While loop executes the code until the condition is false. Syntax: while(condition){ //code } Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i ); i++; } } Output: 20...
