Array help
hi, still getting the hand of it but i have a program i created thats outputting the memory location or something but not the data stored there. this should be the link to the program if you want to take a look at it. https://code.sololearn.com/cuxyN03y9n2t/?ref=app //maas--changing that still throws garbage and the [x] worked to store them just fine till i made the array a variable length by moving it. after that it started throwing garbage.

for (int i = 0; i<s; i++){
cout << "Enter a number for "<<i+1<<": ";
cin >> x;
cout<<""<<x<<endl;
numbers[x];
//The main problem is here!
}
you are not assigning array element to any value so it throws garbage values when accessed.
So just replace
numbers[x] with
numbers[i] = x
EDIT :
for (int i = s; i>0 ; i--){
cout<<"value "<<i<<" = ";
cout<<numbers[x];
//problem also lies here
cout<<""<<endl;
}
replace numbers[x] with numbers[i]
now it must work fine!

This is the edited code wich must work fine:
#include <iostream>
using namespace std;
//to start type a number to determine how many slots to fill and hit enter.
//type any whole number and enter.
//repeat to fill all slots.
//example: 5
// : 1
// : 2
// : 3
// : 4
// : 5
//on the bottom the values stored in the array are not being printed.
//this has been bugging me for a while.
//can anyone leave a comment to help me change it.
//i want to output the data stored in the array and not the memory location, i guess?
int main(){
int s, x;
cout<<"how many players? ";
cin>>s;
cout<<s<<endl;
//i moved the array from the top to here so a value will be assigned to 's' so the array will have a variable length.
int numbers[s];
for (int i = 0; i<s; i++){
cout << "Enter a number for "<<i+1<<": ";
cin >> x;
cout<<""<<x<<endl;
numbers[i]=x;
}
//but when i did that numbers[x] stopped outputting the value and started...this?
for (int i = s; i>0 ; i--){
cout<<"value "<<i<<" = ";
cout<<numbers[i];
cout<<""<<endl;
}
//i had all of this set up in a class and array type but i moved it over here to simplify it before 'class'ing it up once more.
return 0;
}

Ok, one last thing, an array (lets call it arr) of length n will have elements from arr[0] to arr[n-1], so this:
for (int i = s; i>0 ; i--){
cout<<"value "<<i<<" = ";
cout<<numbers[i];
cout<<""<<endl;
}
has to be change to either:
[...]
cout<<numbers[i-1];
[...]
or:
for (int i = s - 1; i >= 0; i--)
[...]
or:
for (int i = 0; i < s; i++)
[...]
