無法獲取輸入字符串數據

Question

我想從用戶那裏得到輸入字符串，以避免空間我用gets_s它輸出這樣的錯誤：

char str[] = "", symb; 
    int count = 0; 
    cout << "Please enter String: "; 
    gets_s(str); 
    cout << "Which character you want to find: "; 
    symb = getchar(); 

    for (int i = 0; i < strlen(str); i++) 
    { 
     if (str[i]==symb) 
     { 
      count++; 
     } 
    } 

    cout << "Character: " << symb << " found " << count << " times."; 

Answer 1

在C++中常見的字符串輸入成語涉及std::string和std::getline：

string text; 
cout << "Please enter String: "; 
getline(cin, text); 

的string包括搜索的方法，如find。
