There wasn't much reasoning on which of these my question was lacking on, so I'll try to improve all of those qualities.My question was more so I could have a better understanding of what goes on when you simply create a string "like this" without storing the address of that string ...
string z = "Hello"; LPTSTR x = new TCHAR[z.size() + 1]; strcpy(x, z.c_str()); //Now x is a copy, but remember to delete the allocated memory once is not needed. BUT if UNICODE is #defined, then LPCTSTR becomes LPWSTR and then the above doesn't even compile. You'll hav...
We copy the string, which the str pointer points to, to the buffer array of type char [10] using strcpy(). If the length of the string that str points is longer than the length of buffer, which is 10, then we have a stack buffer overflow problem. 3. Using gcc gcc is the ...

That would defeat the purpose of using a char* as the status flag. Making a copy of the string is a comparatively expensive operation. Assigning a pointer value is both atomic and inexpensive - like making an integer assignment. Also, I think char* = std:string.c_str() poses the same ...
strcpy and strcat copy from a source buffer to a destination buffer. The only check is the check for a null terminator in the source buffer/string. There is no way it can check if there's enough space in the destination. Your callstrcat(mass[i], mass1[i])attempts to append to the ...
Quote>Suppose if we have a string larger than MAX_LENGTH, then this method will fail to copy. Quote>If we have predefined string length, then we can use this method. Since you can get the length of the string using str.GetLength() ...
Using the same example as above, if you rewind back to Step 2, you'll see a bunch of ? representing uninitialized values on the stack when main() first starts running:C (C17 + GNU extensions) 1 #include <stdio.h> 2 #include <string.h> 3 4 int x = 12345; 5 6 int main(...
1 Copy hecht answer DTS Engineer Apple Jun ’20 exec a child process I’m presuming that “child process” means you plan to fork and exec (or, preferably, using a higher-level API, like posix_spawn, NSTask, Process, and so on). Would that work … ? Yes, with one caveat...
The toString() function is passed a pointer to an instance of a class and returns a string (char * means "string"). The clone() function is passed a pointer to an instance of a class and returns a copy (clone) of the instance. The delete() function is passed a pointer to an ...
