In this program, we will create a user-defined function. Here we will pass an array as an argument and calculate the sum of all array elements and return the result.

Program/Source Code

The source code to pass an array to the user-defined function is given below. The given program is compiled and executed successfully.

# Ruby program to pass an array to the 
# user define function

def MyFun(arr)
   sum=0;
   i=0;
   while i<arr.length
     sum = sum + arr[i];
     i=i + 1;
   end
   return sum;
end

arr = Array(1..5);   

print "Sum of array elements is: ",MyFun(arr);

Output
