【C++】统计一段话中字母、数字、空格、标点、其他和总共，程序

//输入一段话，以‘@’结尾，我们将统计字母、空格、数字、标点、其他、总数
#include <iostream>
#include <cctype>
int main()

	using namespace std;
	cout << "输入一段话，以‘@’结尾，我们将统计字母、空格、数字、标点、其他、总数" << endl;

	char ch;
	int space = 0;

	int chars = 0;
	int punct = 0;
	int others = 0;
	int all = 0;

	cin.get(ch);
	while (ch !='@')

		if (isalpha(ch))
			chars++;

			space++;
		else if (isdigit(ch))
			digits++;
