DEV C++ 5.8.3 strtok problem

[Ahmet]

Hi,

I have mini program in C. Dev C++ compile but .exe file does not work in DOS terminal. I test with Borland compiler 5.5 version with no problem. Please check my program.

OS: WIN 8.1

Thank you

Ahmet

/***** my program *****/

include <stdio.h>

include <stdlib.h>

include <string.h>

/ run this program using the console pauser or add your own getch, system("pause") or input loop /

int main(int argc, char *argv[]) {

char *p1 = "missi,ssi pi";

char *p2 = "abracad abra";

char *p4,*p3 = "A dingbat is animal";

printf("%s",strtok(p1,"ism"));

printf("%s\n",strtok(p2,"abr"));

p4 = strchr(p3, 'b');

printf("%c %s",*p3,p4);

return 0;

}

I found the reason , char p1,p2,*p3 are constant declarations (C99) but after compiling no warning !

In practise, GCC is behaving as expected because:
1.) You are actually manipulating constants.
2.) GCC doc on warning messages switches teach us :
(refer to https://gcc.gnu.org/onlinedocs/gcc-3.0/gcc_3.html )

-Wwrite-strings
Give string constants the type const char[length] so that copying the address of one into a non-const char * pointer will get a warning. These warnings will help you find at compile time code that can try to write into a string constant, but only if you have been very careful about using const in declarations and prototypes. Otherwise, it will just be a nuisance; this is why we did not make `-Wall' request these warnings.

A possible (trivial?) solution could be:
char p1[32] = "missi,ssi pi"; // length is now your new problem...
