Sample Program
Problem statement: Calculate the average age of a class of ten students. Prompt the user to enter the age of each student. Solution: Lets first sort out the problem. In the problem we will take the ages of ten students from the user. To store these ages we will use ten variables, one for each student’s age. We will take the ages of students in whole numbers (in years only, like 10, 12, 15 etc), so we will use the variables of data type int. The variables declaration statement in our program will be as follow: int age1, age2, age3, age4, age5, age6, age7, age8, age9, age10; We have declared all the ten variables in a single line by using comma separator (,). This is a short method to declare a number of variables of the same data type.
