C++, user input check for '\0' stops at spaces?

Question

If the user inputs a sentence containing spaces the while loop stops at one of these spaces. Why is this happening? are '\0' and a space the same or did i do something else wrong? ``` int main ( ) { char user_input[200]; cin>>user_input; int i=0; while(user_input[i]!='\0') { i++; } cout<

Accepted Answer

`\0` is the null terminating character with ASCII code `0`. Space is another character with ASCII 32 i suppose. In fact you are doing this.

```
cin >> user_input;
```

It takes input till you press space or enter. So no space is present in your `user_input` string. Use this instead of `cin`.

```
cin.getline (user_input, 200, '\0') ;
```
