}
Try;#include <iostream.h>
#include <string.h>
main()
{
char *test;
test = NULL; //here you are assigning the pointer to NULL
*test = 'x'; //Now you are trying to fill a NULL pointer...not good
cout << *test << endl;
}
#include <iostream.h>
#include <string.h>
int main(void)
{
char *test = new char;
//test = NULL;
*test = 'x';
cout << *test << endl;
delete test;
}
how bout this one though :
#include <iostream.h>
#include <string.h>
main()
{
char *str;
str = new char[10];
strcpy(str, "hello");
delete [] str;
cout << str << endl;
char *str2 = new char[10];
strcpy(str2, "dolly");
cout << str << " " << str2 << endl;
}
Ummm... what are you trying to do here?
Take out the 'delete' line (what's it there for?) and try it again.

Any reference to str after this point is broken
Whether you use int main() or int main(void), you'll need to return, usually return 0;
As far as I know, you can't use main() or main (void), You can use void main()
> You can use void main()
No you can't (not unless your compiler is also broken)
I just ran this code on MSVC 6.0 and it ran fine. I know it's not recommended, but it works.
Code:#include <iostream> using std::cout; void main() { cout << "Hello world"; return; }
Just because some piece of code compiles and runs doesn't mean that its legal c/c++. Read a copy of the c and c++ standards. main() always returns an int.
The value of this int is seen usually as an error code by the operating system. Returning a value of 0 means that your app finished its work all well and good.Any non-zero value can indicate to the operating system that an error occurred during the running of your app.
Free the weed!! Class B to class C is not good enough!!
