Answer:
c.Null Terminator.
Explanation:
in memory C++ automatically places the null terminator also called null pointer at the end of the string.For example:-
#include<iostream>
using namespace std;
int main()
{
char s[200];
s="every thing is great";
int i=0;
while(s[i]!='\0')
{
cout<<s[i];
i++;
}
return 0;
}
We have taken a string and stored "every thing is great" in it after the next position of the character t in the string there will be a null character.Which C++ automatically places at the end.That's why we are running a loop till the character in the string is not '\0' null character
