Program Of For LOOP in C

#include<stdio.h>

#include<conio.h>

main()

{

int i;

clrscr();

printf("\n================== Ascending Order========================\n");

for(i=1;i<=10;i++)

{

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

}

printf("\n================== Descending Order========================\n");

for(i=10;i>=1;i--)

{

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

}

getch();

}

In computer science a for loop is a programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement .
There are three parts that are separated by semi-colons in control block of the Cfor loop.
initialization_expression is executed before execution of the loop starts. The initialization_expression is typically used to initialize a counter for the number of loop iterations. You can initialize a counter for the loop in this part.
The execution of the loop continues until the loop_condition is false. This expression is checked at the beginning of each loop iteration.
The increment_expression, is usually used to increase (or decrease) the loop counter. This part is executed at the end of each loop iteration.
