C++高手帮我看看下面的程序怎么会报错啊！

[hmzgz81]

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

#define ELBA "Able was I ere I saw Elba"

int main ()
{

char *pszElba = ELBA;
char ch;

int x = 0;


int max = strlen (pszElba);
printf ("%s\n", pszElba);
while (x < max / 2)
{
ch = pszElba[x];
pszElba[x] = pszElba[max - x - 1];　／／在这里报错了
pszElba[max - x - 1] = ch;
++x;
}
printf ("%s\n", pszElba);
return (0);
}

char pszElba[MAX_PATH] = ELBA;

这是个常量字符串，只读。

可是我把他改成这样也不行啊!
#include <stdio.h>
#include <string.h>

//#define ELBA "Able was I ere I saw Elba"

int main ()
{

char *pszElba = "Able was I ere I saw Elba";
char ch;

int x = 0;


int max = strlen (pszElba);
printf ("%s\n", pszElba);
while (x < max / 2)
{
ch = pszElba[x];
pszElba[x] = pszElba[max - x - 1];　／／在这里报错了
pszElba[max - x - 1] = ch;
++x;
}
printf ("%s\n", pszElba);
return (0);
}

[逸学堂]

char *pszElba = ELBA;
修改为
char pszElba[] = ELBA;

[sokewoniu]

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

//#define ELBA "Able was I ere I saw Elba"

int main ()
{

char pszElba[] = "Able was I ere I saw Elba";
char ch;

int x = 0;


int max = strlen (pszElba);
printf ("%s\n", pszElba);
while (x < max / 2)
{
ch = pszElba[x];
pszElba[x] = pszElba[max - x - 1];　／／在这里报错了
pszElba[max - x - 1] = ch;
++x;
}
printf ("%s\n", pszElba);
return (0);
}

char pszElba[] = ELBA;
