Using Relational Operators in C: A Beginner's Guide

A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0. Relational Operators are a bunch of binary operators that are used to check for relations between two operands including equality, greater than, less than, etc. They return a boolean result after the comparison and are extensively used in looping statements as well as conditional if-else statements and so on.

Operator	uses
>	greater than operator
<	less than operator
<=	less than or equal to operator
>=	greater than or equal to operator
==	equality operator

The code is a C program that demonstrates the use of relational operators in C. Here is an explanation of each line of the code:

int a=10,b=5; declares two variables a and b of type int and assigns them the values 10 and 5 respectively.
printf("Greater Than : %d",a>b); uses the relational operator '>' to check if the value of a is greater than b, if yes then it returns 1 otherwise 0. This is printed in the console.
printf("\nLess Than : %d",a < b); uses the relational operator '<' to check if the value of a is less than b, if yes then it returns 1 otherwise 0. This is printed in the console.
printf("\nGreater Than or Equal : %d",a>=b); uses the relational operator '>=' to check if the value of a is greater than or equal to b, if yes then it returns 1 otherwise 0. This is printed in the console.
printf("\nLesser Than or Equal : %d",a<=b); uses the relational operator '<=' to check if the value of a is less than or equal to b, if yes then it returns 1 otherwise 0. This is printed in the console.
printf("\nEqual : %d",a==b); uses the relational operator '==' to check if the value of a is equal to b, if yes then it returns 1 otherwise 0. This is printed in the console.
return 0; The return 0; statement is used to indicate that the main function has completed successfully. The value 0 is returned as the exit status of the program, which indicates a successful execution.

When you run this code, it will perform relational operations on variables and print the results in the console.

    printf("Greater Than            : %d",a>b);

    printf("\nGreater Than or Equal : %d",a>=b);
    printf("\nLesser  Than or Equal : %d",a<=b);
    printf("\nEqual                 : %d",a==b);
 
    return 0;
