How to end program in a do-while (C++)

Here is my code. I am trying to get the entire program to end if it goes into the second if statement inside the do-while loop. But every time I run it, it crashes. I am not sure what I am doing wrong.

#include <iostream>
using namespace std;

int main() {
    int myData[10];
    for(int i=0;i<10;i++){
        myData[i] = 1;
        cout<<myData[i];
    }
    
    do{
        int i;
        cout<<endl<<"Input index: ";
        cin>> i;
        
        int v;
        cout<<endl<<"Input value: ";
        cin>>v;
        
        if(i>=0||i<10){
            myData[i]=v;
            for(int i=0;i<10;i++){
                cout<<myData[i]<<" ";
            }
        }
        
        if (i<0||i>=10){
            cout<<"Index out of range. Exit.";
            return 0;
        }
        
    }while(1);
} 

if(i>=0||i<10){ 

Think about which numbers are either greater than zero or less than ten. I'm sure you realise that is true of all numbers. What you meant to write is

if(i>=0&&i<10){

This explains your crash, you are accessing the myData array with an index that is outside the array bounds.

It's very common for beginners to get && and || confused especially where there is negation involved as well.

Other people have told you the problem:

    if(i>=0||i<10){

I'm going to explain why you hit this. You hit it because you didn't use any whitespace.

    if (i >= 0 && i < 10) {

Please, please, please, for all that is good in the world, use whitespace liberally. You absolutely will have fewer bugs, because my version is far easier to read. Furthermore if you work with older developers (like me) we can actually read your code far more easily.
