Counting in c++

iamkhanglhp (2)
I'm making a program in which it will read an input from a text file and then count the numbers of spaces , characters , words . Here is what i think it would work : First i will transfer the contents from the input.txt into a string , after that i will create 3 strings which contain each of these : spaces , characters , words . Then comparing each of the contents of the intput.txt_string to the other 3 strings .

#include<iostream>

using namespace std;

int main() {
	read_input("input.txt", gameboard,n);
	write_gameboard(cout, gameboard);
	char chucai[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
	char daucach[] = { '_' };
	char kytu[] = "`~1234567890-=!@#$%^&*()+[]\{}|;':,./<>?*";
	char dau[] = { '"' };
	k = 0;
	h = 0;
	a = 0;
	for (int i = 1; i <= n; i++)
	{
		strncmp(chucai, gameboard[i],1);
		strncmp(daucach, gameboard[i],1);
		strncmp(kytu, gameboard[i],1);
		strncmp(dau, gameboard[i],1);
		int x = strncmp(chucai, gameboard[i],1);
		int y = strncmp(daucach, gameboard[i],1);
		int z = strncmp(kytu, gameboard[i],1);
		int o = strncmp(dau, gameboard[i],1);
		if (x == 0) k++&&a++;
		if (y == 0) h++;
		if (z == 0) a++;
		if (o == 0) a++;
	}
	cout << "Numbers of spaces : " << a << endl << "Numbers of characters :" << h << endl << "Numbers of words :" << k << endl;
	system("pause");
	return 0;
}
int read_input(char* filename, char** & gameboard,  int& n) {


	ifstream fin(filename);

	
	fin >> n;

	
	gameboard = new char*[n];
	for (int i = 0; i < n; i++) {
		gameboard[i] = new char[n];
					fin >> gameboard[i];
	}
	fin.close();

	return 0;
}
int write_gameboard(ostream &out, char** & gameboard) {
	for (int row = n - 1; row >= 0; row--) {
			out << gameboard[row] << " ";
		out << endl;
	}
	return 0;
}

and of course it doesnt seem to work.... can anybody tell me where im wrong :( im so frustrated with this for days now . Thank you.
