For inputting strings, C offers several functions, includingscanf(),gets(), andfgets(). Whilescanf()andgets()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 characters to read,...
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. ...

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...

下面,对分别对C风格的字符串输入和C++风格的字符串输入进行探讨。 Scanf读入字符串 在使用fscanf(fptr, "%s", word);方式读入字符串时,格式串"%s"上可以加长度限定,但不是必须的。 格式串上没有长度限定时 通常,我们不会在格式串上加长度限定。但是这种写法是不安全的,比如有下面的一段程序: ...
