Multiple Conditions in a for loop in C

Introduction

Multiple variables can be initialized as well as multiple conditions, and propagations can be made in a single ‘for’ loop by just using a comma ‘,’. In this article we will explore the use of Multiple Conditions in a for loop in C.

Example

Let us write a program to change values of 2 variables, ‘x’ and ‘y’, simultaneously from ‘1 to 5’ and ‘5 to 1’ respectively.

#include<stdio.h>

int main()

{

            int x,y;

            for(x=1,y=5; x<=5,y>=1; x++,y--)

            {

                        printf("x=%d\ty=%d\n",x,y);

            }

}

Output

Multiple Conditions in a for loop in C

Explanation

The above output is only possible when the initialisation, condition, and propagation steps of both variables were written in a single ‘for’ loop.

Note: ‘\t’ is used to generate a tab space like ‘\n’ gives a newline.
