Program Explanation

In this C# program, we are reading the limit of the ‘array’ size. Using for loop enter the coefficient element values of an array. If condition statement, is used to check that the value of ‘i’ variable is equal to 1. If the condition is true then execute the statement and increment the value of the ‘count’ variable. Print the counted number of 1’s in the entered number.
