Why doesn't the following line of code pause my program?

cin.ignore (numeric_limits : :max(), ' ');

If I don't use this line of code to pause my program I will receive a zero. It has happened before. It hurts.

I just can't seem to get it to work.

This is my program:

/* module9ProgrammingAssignment.cpp : This program dynamically allocates an array large enough to hold a

user-defined number of test scores, sorts them, and displays them with the average score by passing array

to separate functions.*/

void getScores(double* score, int size);

void displayScores(double* score, int size, double avg);

void sort(double* score, int size);

double average(double* score, int numScores);

int main()

{

//declaring and initializing variables

double *score = 0, avg = 0;

int size = 0;

//get user-defined number of test sores (size of array)

cout << "How many test grades will you input today? ";

cin >> size;

cout << endl;

score = new double[size]; //create array to hold scores

//call functions

getScores(score, size);

sort(score, size);

avg = average(score, size);

displayScores(score, size, avg);
