Question

I am new to C++. I am trying to read through the array of numbers and count the amount of numbers in the array that are equal to the user entered number. I am not sure what to do next to get it to make number = number1 and count it. I hope this makes sense. Thanks.

#include <iostream>
using namespace std;

int main()
{
    int number[20] = {80, 52, 25, 71, 56, 90, 87, 10, 32, 80, 2, 67, 73, 50, 52, 73, 72, 20, 86, 99};

    int numberCount = 0;
    int number1 = 0;

    cout << "Enter a number between 0 and 100: ";
    cin >> number1;

    while(number1>100 || number1<0) 
    {
        cout << "Invalid number,enter again" << endl;
        cin >> number1;
    }

    for(i = 0; i < 20; i = i + 1)
    {

    }

    system("pause");
    return 0;    
}

There’s a function in the standard library for this, in the <algorithm> header:

int numberCount = std::count(number, number + 20, number1);
