To use strcpy or not


To use strcpy or not

Does that help The assignment works without allocating any extra memory.
If you use strcpy(), you have to assign enough memory to x[0] before you do the copy (strlen(q[0]) + 1 bytes minimum), and you have to ensure it is released at the appropriate time.

Implementing a new strcpy function redefines the library function strcpy?

I wish did fix the issue. It is said that we can write multiple declarations but only one definition. Now if I implement my own strcpy function with the same prototype : , C11(ISO/IEC 9899:201x) §7.1.3 Reserved Identifiers
Multiple consecutive strcpy(), display contains bits of every next strcpy()

Does that help These 2 lines show what's going wrong:
Following line declares an array of char cP1_Move2_Name initialized with "POUND". The size of this array is exactly 6 bytes, that is the 5 characters from "POUND" plus one for the NUL terminator (strings are terminated by a NUL character, read the chapter dealing with string in your C textbook for more details):
code :
char cP1_Move2_Name[] = "POUND";
strcpy(cP1_Move2_Name,"EARTHQUAKE");
#define MAXSTRINGLENGTH 100
...
char cP1_Pokemon_Name[MAXSTRINGLENGTH] = "POKEMON";
char cP1_Move1_Name[MAXSTRINGLENGTH] = "TACKLE";
char cP1_Move2_Name[MAXSTRINGLENGTH] = "POUND";
...
etc.
Why can't I do strcpy?

To fix the issue you can do , You are doing it wrong:
code :
#include<stdio.h>
#include<string.h>
#include<stdlib.h>

int main() {
   const char* hello = "Hello, World!";
   char *str = malloc(strlen(hello)+1);

   strcpy(str,hello);
   printf("%s\n", str);
   free(str);
   return 0;
}

wish of those help Arrays in C are non-assignable and non-copy-initializable. That's just how arrays are in C. Historically, in value context (on the RHS of assignment) arrays decay to pointers, which is what formally prevents assignment and copy-initialization. This applies to all arrays, not only to char arrays.
C language inherits this arrays behavior from its predecessors - B and BCPL languages. In those languages arrays were represented by physical pointers. (And obviously re-assignment of pointers is not what you'd want to happen when you assign one array to another.) In C language arrays are not pointers, yet they do "simulate" the historical behavior of B and BCPL arrays by decaying to pointers in most cases. This historical legacy is what keeps C arrays non-copyable to this day.
Alternative to strcpy? or fix to strcpy in program?
