Unit 5: Arrays and String

5.1.2. Declaring (defining) an Array

An array, in C++, has the following syntax:

            data_type array_name[Array size];

Note: 

• The data_type is the variable data type whether it is float, int, long int, char, etc.
• The variable_name is whatever you want to call it. The size is the number of elements in the array.

Example:

                int marks[10];
                float exp_result[100]; etc.
