However, some statements can be placed in the body of a for loop, which will exit the loop without the evaluation needing to return false. These are statements such as break, return, or goto. To demonstrate a more functional for loop in C programming language, take the example of a progr...
Example 1: To Find The Factorial Of A Number Using For Loop In C++ In this example, we’ll use a C++ for loop to calculate the factorial of a given number step by step. Code Example: #include <iostream> using namespace std; int main() { int n, factorial = 1; cout << "Enter ...
If the test condition is true, the body of the loop executes The update expression gets updated Again the test condition is evaluated The process repeats until the test condition becomes false. Example: For loop in C Compiler // Program to print numbers from 1 to 10 #include <stdio.h> in...
Example 2: for loop // Program to calculate the sum of first n natural numbers // Positive integers 1,2,3...n are known as natural numbers #include <stdio.h> int main() { int num, count, sum = 0; printf("Enter a positive integer: "); scanf("%d", &num); // for loop term...
But there are use cases that are much easier to perform in a while() loop. For example, the while() loop might continually request input from the useruntilthe user gives the correct input. The “For” loop vs. “Switch” case in C ...
To demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:Example for (i = 0; i <= 100; i += 10) { printf("%d\n", i);} Try it Yourself » In this example, we create a program that only print even numbers between 0 and 10 ...
In the above example, rangeDeclaration-int var rangeExpression-num Working of ranged for loop in C++ Example 1: Ranged for Loop Using Array #include<iostream>usingnamespacestd;intmain(){// initialize arrayintnumArray[] = {1,2,3,4,5};// use of ranged for loop to print array elementsfo...
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++;
Case5 (Blank Loop): This example shows that loop can execute even if there is no statement in the block for execution on each iteration. Case6 (Multiple variables and conditions): Variables ‘i’ and ‘k’ are initialized to 0; condition is to execute loop when ‘i’ is lesser than ‘...
C for 循环 C 循环for 循环允许您编写一个执行指定次数的循环控制结构。语法C 语言中 for 循环的语法:for ( init; condition; increment ) { statement(s); }下面是 for 循环的控制流:init 会首先被执行,且只会执行一次。这一步允许您声明并初始化任何循环控制变量。您也可以不在这里写任何语句,只要有一个...
