return keyword in C#
The return statement is used to return value. When a program calls a function, the program control is transferred to the called function.
The following is an example to learn about the usage of return statement in C#. Here, we are finding the average and returning the result using the return statement.
double getAverage(int[] arr, int size) { int i; double avg; int sum = 0; for (i = 0; i < size; ++i) { sum += arr[i]; } avg = (double)sum / size; return avg; }
Here is the complete example −
Example
using System; namespace ArrayApplication { class MyArray { double getAverage(int[] arr, int size) { int i; double avg; int sum = 0; for (i = 0; i < size; ++i) { sum += arr[i]; } avg = (double)sum / size; return avg; } static void Main(string[] args) { MyArray app = new MyArray(); /* an int array with 5 elements */ int [] balance = new int[]{1000, 2, 3, 17, 50}; double avg; /* pass pointer to the array as an argument */ avg = app.getAverage(balance, 5 ) ; /* output the returned value */ Console.WriteLine( "Average value is: {0} ", avg ); Console.ReadKey(); } } }
