(3, a, b, c); return 0; } 2、字串定位程序: # include stdafx.h # include iostream # include string using namespace std; int findsubstr (which char * mainstr, which char * substr) { / / which char * p; / / which char * q; / / p = mainstr; / / q = substr; int ...
此方法接受一个string类型参数,但是却没有检测此数值是否 有足够的空间来拷贝数据。所以这里我们一般用 fgets() 方法将来的更好。 Answer: The hidden problem with the code above is the use of the function gets(). This function accepts a string from stdin without checking the capacity of buffer in w...
14.difference between #include "string.h" and #include <cstring> the first one is in a C-type way, contents of both are same, but functions in the first one are not in namespace std!! 15.when do comparison in for() statement, why != is preferred than < ?
