C Programming for Beginners : The For Loop

Introduction

It does the same thing as the while loop. It means, the for loop can be used to execute a group of statements repeatedly depending upon the number of elements in a sequence

Syntax :

Example of for loop in C :

Printing numbers from 0 to 10 :

0
1
2
3
4
5
6
7
8
9
10

Breakdown of the Code :

for (int i = 0; i <= 10; i++)

Here we declared the for loop and and an integer i . Initially i is 0. Then we stated the for loop should execute the codes if i remains less than or equal to 10. The we stated to increment i to avoid an infinite loop.

{
    printf("%d\n", i);
}

Code inside the loop states to print the variable i through each iteration.

Some Examples :

Print the even numbers from 1 to 10 using a for loop.

2
4
6
8
10

Display numbers from 5 to 1 in descending order.

5
4
3
2
1

Note the we stated the condition as “as long as i is greater than or equal to 1” as we decremented i for each iteration.
