0 The ! operator in C

The ! is the logical NOT operator. This reverses the result of the expression it operates on.For example, if expression evaluates to true, the applying ! operator to it results to false and vice versa.

Syntax:

!(expression)

Example:

 i=9;

!(i>5)

Since i is greater than 5 , so expression evaluates to true but after applying ! operator, it results into false.

/*Demonstration of ! operator */

#include<stdio.h>

int main()

 {

  int i=9;

  if(!(i>6))

    printf("Does ! operator  amazing?");

  else

    printf("Does ! operator sound confusing?");

  return 0;

 }
