What is For Loops in C Programming ?

In C programming, a for loop is a way to repeat a block of code for a certain number of times or until a certain condition is met. It has three parts:

1. Initialization: In this part, you can declare and initialize any variables that will be used in the loop.
2. Condition: In this part, you specify a condition that determines whether the loop should continue executing or not. The loop will keep running as long as the condition is true.
3. Increment/Decrement: In this part, you can specify how the loop counter variable will be updated after each iteration of the loop. This is usually done by incrementing or decrementing the counter.

The syntax for a for loop in C programming looks like this:

for (initialization; condition; increment/decrement) {
    // Code to be executed repeatedly
}

With a for loop, you can easily iterate over an array, process data, or perform any repetitive task efficiently and with ease.

Flow Chart Of For Loop

Example Of For Loops in C Programming

#include <stdio.h>

int main() {
    int i;  // declare a variable for the loop counter
    
    for (i = 1; i <= 10; i++) {
        printf("%d\n", i);  // print the value of i
    }
    
    return 0;
}

In this example, the for loop consists of three parts:

1. Initialization: We declare a variable i to use as the loop counter.
2. Condition: We set the condition for the loop to continue: i must be less than or equal to 10.
3. Increment/Decrement: We increment i by 1 after each iteration of the loop.

The loop body simply prints the value of i using the printf() function. The loop runs 10 times, printing the numbers from 1 to 10 on separate lines.
