C++: “Multi-character character constant” warning when reading from a file into char array
#include <fstream>
#include <iostream>
using namespace std;
int main()
ifstream input;
input.open("kr.txt");
int n;
input >> n;
for(int i = 0; i < n; i++)
char line[16];
input.ignore(256, '/n');
input.get(eil, 16);
return 0;
I get the warning at the "input.ignore()".
My file looks like this. 15 spaces separate the beginning of the line to the first number.

What's'/n'? It isn't the newline symbol.

/n is constant consisting of two chars, '/' and 'n'and you are not quoting it as a string, using ", but as a char, using ', hence warning.
Maybe you wanted to use backslash instead of slash, i.e. 'n'?

Yep, as ForceBru replied to the question, my problem is that I can't tell the difference between "/n" and "n"
