更改字符指针数组中的内容

Question

这看起来应该很容易，但我在这上面花了太多时间。希望有人能提供帮助。

char *string_labels[5] = { "one", "two", "three", "four", "five" };

void myFunction(void)
{

    //can print them just like expected
    for(i=0; i < 5; i++)
    {
        printf("%s\n", string_labels[i]);
    }

    //how can i change the contents of one of the elements??
    sprintf(string_labels[0], "xxx"); <-crashes

}

它崩溃是因为它在只读内存中。尝试

char string_labels[][6] = { "one", "two", "three", "four", "five" };
sprintf(string_labels[0], "xxx");
