What are relational operators in C language?

These are used for comparing the two expressions.

Operator	Description	Example	a=10,b=20	Output
<	less than	a<b	10<20	1
<=	less than (or) equal to	a<=b	10<=20	1
>	greater than	a>b	10>20	0
>=	greater than (or) equal to	a>=b	10>=20	0
==	equal to	a==b	10==20	0
!=	not equal to	a!=b	10!=20	1

Relational expression output is either true (1) (or) false (0).

Algorithm

Follow the algorithm given below −

START
Step 1: Declare integer variables.
Step 2: Read all variables at runtime.
Step 3: Perform relational operations.
   i. a<b
   ii. a<=b
   iii. a>b
   iv. a>=b
   v. a==b
   vi. a!=b
Step 4: Print all computed values.

Example

Following is the C program to compute relational operators −

Live Demo

#include<stdio.h>
main (){
   int a,b;
   printf("enter a,b values:\n");
   scanf("%d%d",&a,&b);
   printf("%d\n",a<b);
   printf("%d\n",a<=b);
   printf("%d\n",a>b);
   printf("%d\n",b>=a);
   printf("%d\n",a==b);
   printf("%d\n",a!=b);
}

Output

You will see the following output −

enter a,b values:
120 340
1
1
0
1
0
1
