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
