For Loop in C
For Loop Definition
For loop in C is defined as control structure, which allows to execute the block of codes for specific number of times until the condition is false. For loop is also known as entry-controlled loop.
Syntax :
for(initialization; checking; updation)
{ // block of codes }
Working of for Loop :
The for loop follows a very organized methodology in which it first initializes a condition, then tests the condition, and then performs conditional statements before updating data.
It has 3 parameters : Initialization, test expression and updation.
Initialization :
The conditional variable that iterates the value or aids in checking the condition is accepted as the first parameter of a basic for loop, which accepts it.
Test Expression :
The Second parameter of a fundamental for loop defines the expression , if the check expression is true, the loop iterates further; otherwise, it stops and move out of the loop.
Updation :
A basic for loop’s third parameter specifies whether to increment or decrement the conditional variable that iterates the code in response to the condition.
Body of for loop :
Body is known as a group of statements, such as variables, functions, etc.
When an iteration is successful, these are automatically carried out, and they continue to do so until the condition is not met.
#include <stdio.h>
int main() {
for(int i=0; i<=5; i++){
printf("PrepInsta\n");
}
return 0;
}
Output :
PrepInsta PrepInsta PrepInsta PrepInsta PrepInsta PrepInsta
In the above example, the value of i initialize at 0 and for every increment till the condition (i<=5) PrepInsta will be print.
