Unit 5: Arrays and String

5.1.3. Initialization of Array

• To initialize an array, the initializing values are enclosed within the curly braces in the declaration and placed following an equal sign after the array name. Here is an example:

            int myArray[5] = {1, 2, 3, 4, 5, 6};

• If the number of values supplied are less than the actual number of item in the list then extra spaces in the array will be filled in with zeroes.
• If the number of values supplied is greater than the actual size of the array then the compiler will give an error message.
• If the size of the array is not supplied, the compiler will count the number of items in the initialization list and fix that as the array size. For example:

                    int myArray[] = {5, 6, 8, 6, 9, 6};
