Arrays are sequences of objects of the same type. We can declare an array of type char as follows:

int main()

{

    char arr[5];

}

This example declares an array of 5 characters. To declare an array of type int which holds five elements, we would use:

int main()

}

Initialization list in our example { 10, 20, 30, 40, 50 } is marked with braces and elements separated by commas. This initialization list initializes our array with the values in the list. The first ...
