定义string变量,想要读入空格,可以用getline函数,参数为(cin,变量)
#include <iostream> using namespace std; #include <string> int main() { string str1,str2; while (getline(cin,str1) && str1[0] != '#') { int count; getline(cin, str2); for (int i = 0; i < str1.size(); i++){ count = 0; for (int j = 0; j < str2.size(); j++) if (str1[i] == str2[j]) count++; cout << str1[i] << " "<< count << endl; //按格式输出 } } } // 64 位输出请用 printf("%lld")
