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 −
#include<stdio.h>
main (){
int a,b;
printf("enter a,b values:
");
scanf("%d%d",&a,&b);
printf("%d
",a<b);
printf("%d
",a<=b);
printf("%d
",a>b);
printf("%d
",b>=a);
printf("%d
",a==b);
printf("%d
",a!=b);
}Output
You will see the following output −
enter a,b values: 120 340 1 1 0 1 0 1
