Chapter 8.2, Problem 8.4CP

Explanation of Solution

Foreach loop:

• In C#, foreach loop is used to iterate over the elements of the collection, where the collection includes an array or a list.
• In this loop, it is necessary to enclose the statements in curly braces.
• Loop counter variable is not declared or initialized, instead, a variable of same type as the base type of the array, followed by a colon, which is then followed by the array name.
• Inside the loop body, the loop variables can be used instead of using the indexed array element.
