    How to let the user input values for an array...

    I learned to program in BASIC, and have just started useing C++. Having a little trouble with the syntax.

    I am writing a basic program that averages numbers. In the first part, the user inputs a whole number greater than 1, which is stored as the "number" variable. Then...

    int array(number);
    {
    cout<<"\nEnter a number: ";
    cin>> //What do I put here?

    I want the user to enter any number, and have it stored as the first slot (x) in the array, then have another line that increases the value of x by one, checks to see if it equals "number," and loop back around if it doesn't.

    Something like this, but I don't know the correct syntax:

    int array(number);
    x=1
    {
    cout<<"\nEnter a number: ";
    cin>> array(x)
    If (x==number)
    {
    goto the rest of the program
    Else
    {
    goto the start and let the user input another number.
    }

    I heard that using goto statements wasn't good programming, and that there were other ways of doing it. What are these ways?

    Thx!

    why would you need an array at all?

    here's my suggestion:
    Code:
    #include <iostream>
    
    int main() {
      int t=0,x=0,c=0;
      cout << "type a list of numbers, and end the list with a negative number" << endl;
      while (x >= 0) {
        t += x;
        cout << "Insert # " << ++c << endl;
        cin >> x;
      }
      cout << "Out of " << c-1 << " numbers, the average is " << (double)t / (double)(c-1) << endl;
    }

    hey, even if u use an array, then u can use this code:

    #include<iostream.h>
    void main()
    {
    int array[100];
    // 1008 is for the maximum no of the numbers that user can enter
    int n;
    cout<<"Enter how many numbers u want to enter: ";
    cin>>n;
    for(int i=0;i<n;i++)
    {
    cout<<"Enter the Number: ";
    cin>>array[i];
    }
    // the rest is the average which can be easily done.
    }
