How to get a string by getline?

Question

Hi Everybody! I wanted to code a program but I was dumber than I expected😅 I just forgot how to get a char array without knowing the size of it. I just tried this code:

int main(){
char a[1000];
int counter =0;
cin>>a[counter]; counter++;
while(a[counter-1]!='/0')
{ cin>>a[counter]; counter++;}
}
but when I ran this program, it didn't stop getting inputs.
Then, I tried getline(cin,/*string*/ s), but there was an error😐 If you know the answer, please help me❤

Answer 5

@jamie I tried both '/0' and ''\0' . about getline I did the same but there was an error for getline and I don't know what's wrong with it.

You want your program to end reading input when you press enter? Then why are you comparing with a '\0' ?

Your current code (after replacement of '/0' by '\0') requires the console to read a \0 to stop reading. But you cannot input it directly, and you need to use 'Alt + ASCII Code' for that, if you wish to keep using a \0 to end the read operation.

Answer 7

@Kinshuk Vasisht you mean I must to put 'Alt+ASCIICode' instead of '\0' ?
