Write а cоmplete C++ prоgrаm (frоm #include stаtements to return 0;) that performs the following: Initializes a vector with 20 random integers in the range 1 to 100. Outputs the values of the vector on one line, each separated by a space. Computes and outputs the sum of the values at even indices: 0, 2, 4, 6, etc. Computes and outputs the sum of every other odd index value: 1, 5, 9, 13, etc. Computes and outputs the average of the values in the vector using a function: double average(vector& v); Sample Output: 71 11 54 51 63 89 100 4 60 65 2 63 65 77 84 82 87 96 71 1465733860.45 You must write and test your solution in your C++ IDE.
