What will be the output of the following C++ code?

#include <cmath> 
#include <iostream> 
using namespace std; 
void Cipher(string str) 
{ 
    int r, c; 
    for (int i = 0; str[i]; i++) 
    { 
 
	r = ceil((str[i] - 'a') / 5) + 1; 
 
 
	c = ((str[i] - 'a') % 5) + 1; 
 
 
	if (str[i] == 'k') 
        { 
	    r = r - 1; 
	    c = 5 - c + 1; 
	} 
 
 
	else if (str[i] >= 'j') 
        { 
	    if (c == 1) 
            { 
		c = 6; 
		r = r - 1; 
	    } 
	    c = c - 1; 
	} 
	cout << r << c; 
    } 
    cout << endl; 
} 
 
int main() 
{ 
    string str = "nsit"; 
    Cipher(str); 
}
