#include <iostream> using namespace std; int main() { string str; getline(cin, str); char c; cin >> c; int cnt = 0; for (int i = 0; i < str.length(); i++) { if (str[i] == c) { cnt++; } if (str[i] > 64 && c > 64) { if (str[i] - c == 32) { cnt++; } if (c - str[i] == 32) { cnt++; } } } cout << cnt; } // 64 位输出请用 printf("%lld")
