This concept is covered in the previous tutorial. There are three types of loops: for, while, and do..while. Each of them has their specific uses. They are all outlined below. FOR - for loops are the most useful type. The syntax for a for loop is ...
C programming has three types of loops. for loop while loop do...while loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop. while loop The syntax of the while loop is: while (testExpression) { // the body of the...
Syntax do{ // code block to be executed } while(condition); Note:The semicolon;after thewhilecondition is required! Do/While Example The example below uses ado/whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed ...
It is another loop like ‘for’ loop in C. But do-while loop allows execution of statements inside block of loop for one time for sure even if condition in loop fails. Basic syntax to use ‘do-while’ loop is: variable initialization; do { statement 1; statement 2; .. .. iteration ...
Output of while loop: Output of do-while loop: b: 11 Note that thewhileloop doesn't take any iterations, but thedo-whileexecutes its body once. This is because the looping condition is verified at the top of the loop block in case ofwhile, and since the condition is false, the prog...
The do...while loopThese loops are explained in detail as under.1. The for loopThe for loop is the most commonly used loop by the programmers and requires us to initialize three conditions in a single line at the start of the loop.SyntaxBelow is the syntax of the for loop -for...
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...
The while loop in C is used when we don’t know the number of iterations.while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process ...
C++ do...while Loop - Learn about the do...while loop in C++, its syntax, and how to use it effectively in your programs.
Awk While Loop Syntax: while(condition) actions while is a keyword. condition is conditional expression actions are body of the while loop which can have one or more statement. If actions has more than one statement, it has to be enclosed with in the curly braces. ...
