Thread: strcpy crashes program when used with a char pointer.

the title says it all.
here's an example code i tested too:

Code:

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

char * str;

int main( void )
{

    strcpy(str, "Hello World!");

    return 0;
}

str is just a pointer. It has no space to hold the string. What you want is a char array with at least enough space to hold the characters (including the null terminating character), and it may as well be declared inside main.

Code:

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

int main(void) {
    char str[100];
    strcpy(str, "Hello World!");
    printf("%s\n", str);
    return 0;
}
