Loops are used in programming to execute a block of code repeatedly until a specified condition is met. In this tutorial, you will learn to create while and do...while loop in C programming with the help of examples.
#include <stdio.h>intmain(void){intx=1;do{printf("%d\n",x);x++;}while(x<=10);} In this example, we’ve created a do while loop that will print out the numbers 1 through 10. The variable x is initialized to 1 and then incremented by 1 each time through the loop. The condit...
C# Do While Loop ADo Whileloop in C# is similar to aWhileloop, except the code in the loop's code block will always execute at least once. This is because the evaluation to determine whether to continue looping is done after the loop has executed instead of before. do{ Console.WriteLine...
4.do whileloop in C In some situations it is necessary to execute body of the loop once before testing the condition. Such situations can be handled with the help ofdo-whileloop. Thedostatement evaluates the body of the loop first and at the end, the condition is checked usingwhilestatemen...
do { } while ( condition );Notice that the condition is tested at the end of the block instead of the beginning, so the block will be executed at least once. If the condition is true, we jump back to the beginning of the block and execute it again. A do..while loop is basically...
Types of Loop in CLet’s get into the three types of loops used in C programming. 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 ...
// infinite while loopwhile(true) {// body of the loop} Here is an example of an infinitedo...whileloop. // infinite do...while loopintcount =1;do{// body of loop}while(count ==1); In the above programs, theconditionis alwaystrue. Hence, the loop body will run for infinite ...
Syntax of do-while Loop in C++In C++, the basic syntax of the do-while is:do { //code body to be executed } while (condition);The description of the above-given syntax is:“do” keyword initiates the loop. “{ }” curly brackets contain the statements that execute it at any cost....
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 loop wi...
