I have a constraint to read the input strings character by character. So I'm checking for \n after each string. But the program is not terminating.
Here's the problem I'm facing in a very short code:
#include <iostream>
using namespace std;
int main()
{
char c;
while(cin >> c)
{
char x;
cin >> x;
while(x != '\n')
{
// print the characters
cin >> x;
}
}
return 0;
}
In the above code, c will have the first character of the string while x will have the rest of characters one by one.

One way of reading character by character, is via std::basic_istream::get.
If you define
char c;
then
std::cin.get(c);
will read the next character into c.
In a loop, you could use it as
while(std::cin.get(c))
