For inputting strings, C offers several functions, including scanf(), gets(), and fgets(). While scanf() and gets() can be used for this purpose, they pose risks of buffer overflow. fgets(), on the other hand, is safer because it allows you to specify the maximum number of character...
scanf()andgets()have the exact same problem with memory overrun. You can easily read in more characters than yourchar*can hold. And of course,scanf()hasThe Steps, too. The solutions are the same. 'Nuff said. Coming next,scanf()/ Reading numbers. ...
Replacing a part of string with another string in C, this is my source code. When I input a string "I am in CSE 2nd year." and replace CSE 2nd(ie loc 9 to 15) by ECE 3rd, I get some garbage vales at the end of string. //splitting a string and replace latter part of string...

1、可以使用scanf，getch，getchar等，但是需要转换到string，cin一般是足够的，使用标准输入流2、判断string字符串长度不能用sizeof，直接使用size()函数，sizeof获得的是其对象的内存大小，可以向下面这样用string strT = "123";int nL = strT.size();if(nL == 3)printf("nL==3\r\n");3...

Likewise, there's _tprintf and _tscanf for printf and scanf. All the 't' versions use TCHARs instead of chars. So how can you apply all this to std::string? Easy. STL already has a wstring class that uses wide characters (defined in the file xstring). Both string and wstring are...
