The program demonstrates the use of various relational operators in C programming. Relational operators are used to compare two values and return a Boolean value (either 0 or 1) based on the result of the comparison. The program uses printf() function to print the return value of each relational operator.

The output of the program will be: Condition : Return Values 10!=10 : 0 10==10 : 1 10>=10 : 1 10<=10 : 1 10!=9 : 1

Here, the relational operator ! = returns 0 if the values being compared are equal and 1 if they are not equal. The relational operator == returns 1 if the values being compared are equal and 0 if they are not equal. The relational operator >= returns 1 if the first value is greater than or equal to the second value, and 0 otherwise. The relational operator <= returns 1 if the first value is less than or equal to the second value, and 0 otherwise.
