Is there a problem with how I am calling the member functions?

April 19, 2022

Write a program with a class called Dice in a file called "Dice.h" that has as a member object a vector that simulates the rolling of a single die a hundred times. as well as a member variable called Size which contains the size of the vector.

In the file Dice.cpp, the Dice class should have the following public member functions defined:

a default constructor which sets all of the values of the vector member object to 0.
roll100() which rolls the die 100 times and records that roll in the vector member object.
calculateRolls() which calculates the number of 1 rolls, the number of 2 rolls, the number of 3 rolls, the number of 4 rolls, the number of 5 rolls, and the number of 6 rolls. The function then displays the number of the respective rolls to the user.
printDice() which displays the contents of the vector to the screen with 10 elements of the vector per line for 10 lines.
