having some problems...

I have the following code:

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define SIZE (sizeof(strings)/4)
int main(void)
{
    int i;
    char *strings[] = {
        "Line1 here",
        "Line2 there",
        "Line3 whatever",
        "Line4 blahhh",
    };
   
    for (i=0; i<SIZE; ++i)
        strings[i] = strrev(strings[i]);
   
    for (i=0; i<SIZE; ++i)
        printf("%s\n",strings[i]);
   
    system("PAUSE");
    return 0;
}

---

I'm having problems with it, when I run it it freezes, but it compiles well, I think I'm not using pointers well.

Thanks in advance.

>> char *strings[]
This is an array of pointers to strings. You are initialising it to pointer to a few string literals. String literals cannot safely be modified.

Try this:

Code:

---

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define SIZE (sizeof(mystrings)/sizeof(mystrings[0]))

int main(void)
{
    int i;
    char mystrings[][100] = {
        "Line1 here",
        "Line2 there",
        "Line3 whatever",
        "Line4 blahhh",
    };
   
    for (i=0; i<SIZE; ++i)
        strrev(mystrings[i]);
   
    for (i=0; i<SIZE; ++i)
        printf("%s\n",mystrings[i]);
   
    system("PAUSE");
    return 0;
}

Thanks Hammer.
