Dividing the program into multiple functions,improve the readability of functions.

Part 2 (Long question)

Question : Define variable and define any three rules for naming a variable ?

 A variable is actually given to memory location as the data physically stored inside the computer memory and the value of  variable can be changed in program.each variable has unique name called identifier and has data type.

Rules of Naming the variable

A variable can only contain alphabets digits and underscore sign.

A variable name must begin with a letter.

A reserve words can not be usee as variable name.

Question : Write a program using for loop in c language that print even numbers from 25 to 35.

    for (int i = 25; i <= 35; i++) {

        if (i % 2 == 0) {

            printf("%d\n", i);

        }

    }

    return 0;

}

Output : 26 28 30 32 34
