将字符串转化为ASCII码并转换为二进制

#include 
using namespace std;

int main() {
	string s;
	long long a[100009], b[100009], d, n, e, f, t, p;
	int k;
	cin >> s;
	system("cls");
	cout << "原文:";
	for (int i = 0; i < s.size(); i++)
		cout  << s[i] << " ";
	cout << endl;
	for (int i = 0; i < s.size(); i++) {
		k = int(s[i]);
		cout << "'" << s[i] << "'" << "转化为ASCII码:"  << k << endl;
		e = k;
		t = 1;
		f = 0;
		do {
			k /= 2;
			n++;
		} while (k);
		b[1] = e;
		for (int i = 1; i <= n; i++) {
			a[i] = b[i] % 2;
			b[i + 1] = b[i] / 2;
			t = t * 10;
			f = f + a[i] * t / 10;
