COMMA OPERATOR

Introduction

You can combine multiple expressions in a single expression using the comma operator.

Program

#include  main() {   int i,j,k;   k = (i = 4, j = 5);   printf("k = %d",k);  } 

Input

 i = 4,j = 5. 

Output

k = 5. 

Explanation

For example, you can write: k = (i = 4, j = 5)

Here the expression is evaluated from left to right, that is, i = 4 is evaluated first then j = 5 is evaluated. The value of the rightmost expression is specified as output, thus k will get the value 5.
