Which statement will invoke this method? TenNums TenNums::operator+(const TenNums& b) { TenNums o; for (int i = 0; i < 10; i++) o.p[i] = p[i] + b.p [i]; return o;} Group of answer choices TenNums a; TenNums b = a; TenNums c = a + b; TenNums c = a.add(b);
C# Write a program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average. An example of how the results should be output is as follows: Test # 0: 89 From average: 6Test # 1: 78 From average: -5 using System;using static System.Console;class TestScoreList{static void Main(){// Write your main here}}
