Step 2:In the second step the condition is checked, where the counter variable is tested for the given condition, if the condition returns true then the C statements inside the body of for loop gets executed, if
Now that we have a clear understanding of the syntax and functionality of the for loop in C++, let's look at a few code examples. 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...
C programming has three types of loops: for loop while loop do...while loop We will learn about for loop in this tutorial. In the next tutorial, we will learn about while and do...while loop. for Loop The syntax of the for loop is: for (initializationStatement; testExpression; update...
In this example, the program asks the user to enter numbers continuously until they enter 0. It keeps calculating the sum of the entered numbers. Once the user enters 0, the loop terminates, and the program prints the total sum. The loop is executed at least once because the condition is...
Syntax and Examples of For Loop in C Programming The essential syntax of a for loop in C is: for ( ; ; ) This for loop lacks an evaluation expression. If nothing is evaluated as true or false, there can be no exit to this loop. If this program ran, it would begin an infinite ...
while loop in C It repeatedly carries out a series of instructions till a condition istrue. It is anentry-controlledloop. Thewhileloop in C is used when we don’t know the number of iterations. while loop Flowchart Syntax while(test condition){//code to be executed} ...
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,只要有一个分号出现即可。
For loop Examples Example - 1: The following program calculate the sum of 1+2+3+...+50. The sum is stated in sum = sum + x, where i takes values from 1 to 50. #include<stdio.h>main(){intsum;intx;sum=0;for(x=1;x<=50;++x)// x take values in {1,2,3,...,50}{sum...
Keep in mind also that the variable is incremented after the code in the loop is run for the first time. WHILE - WHILE loops are very simple. The basic structure is while ( condition ) { Code to execute while the condition is true } The true represents a boolean expression which ...
Now, just as we saw in the for loop, there can be various ways in which we can achieve this result.C while Loop: Example 2Print integers from 1 to 5 using the while loop.#include <stdio.h> int main() { int i; //loop counter //method 1 printf("Method 1...\n"); i=1; ...
