Difference Between & and &&

In this post, we will understand the difference between the ‘&’ and ‘&&’ operators.

& operator

• It is a bitwise operator.

• It evaluates the left and right side of the expression.

• It operates on the ‘Boolean’ datatype (True or False).

• It also operates on bits.

• It is used to check the logical conditions.

• It can also be used to mask off specific bits (like the parity bits).

Example

#include<stdio.h>
int main(){
   int x = 3;
   int y = 4;
   int z = x & y;
   printf ("z = %d", z);
   return 0;
}

&& operator

• It is a logical operator.

• It evaluates the left side of the expression only.

• It operates on ‘Boolean’ datatype only.

• It is used to check the logical conditions.

Example

#include<stdio.h>
int main(){
   int a = 6, b = 3;
   printf("%d", a&&b);
   return 0;
}
