    class negate
        public static void Main()
            int[] a = new int[10];

Program Explanation

This C# program, we are reading the value of 5 elements value using for loop and assign the value to ‘a[]’ array variable. If condition statement is used to check the value of ‘a[]’ variable is greater than 0. If the condition is true, then execute the statement. Assign the value of ‘a[]’ variable to the minus symbol of a[] variable. Hence using foreach loop print negate of positive elements of an array.
