In programming, loops are used to repeat a block of code. In this tutorial, you will learn to create for loop in C programming with the help of examples.
C/C++ 中的循环在我们需要重复执行一个语句块时派上用场。 For 循环是一种重复控制结构,它允许我们编写一个执行特定次数的循环。循环使我们能够在一行中一起执行 n 个步骤。 语法: for(initialization expr;test expr;update expr) { // body of the loop // statements we want to execute } For 循环的...
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...
Real-Life ExamplesTo 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 ...
Example of For loop #include<stdio.h>intmain(){inti;for(i=1;i<=3;i++){printf("%d\n",i);}return0;} Output: 123 Various forms of for loop in C I am using variable num as the counter in all the following examples – 1) Here instead of num++, I’m using num=num+1 which ...
for loop in C 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 )...
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 ...
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 (initialize ; condition ; increment) { //body of the loop //Code ...
Loops in C have a broad range of applications, from loop-driven algorithms to iterative problem-solving. As demonstrated, the syntax for using these loops is relatively straightforward, although their logic must be carefully explored to determine advantage and ease of use. Thanks to this design, ...
