Question

How do I run the while loop until the end of line or null character reached.

Here is my code

#include<iostream>
using namespace std;
main()
{
    char input[20];
    cout<<"Enter a line: ";
    cin>>input;

    while(input!='\0')
    {
        cout<<"This is a text";

    }
    system("pause");
}

Answer 1

try something like:

i = 0;
while ((input[i] != '\0') && i < 20)
{
  cout<<"This is a text";
  i++;
}
