char pointer not work right

[Blaqb0x]

Hi,

suppose I have a struct w/ a char pointer if i try to set the value of this character to a filled char variable I get weird characters.

char Name[ ] = "Nobody";

MyStruct->charPointer = Name;

cout << "my name is " << MyStruct->charPointer <<endl;

gives weird characters instead of the string(not a memory location like 0xcdaddc but symbols)

anyone know why?

MyStruct->charPointer = "Nobody"; <- works fine.

Just a guess here (I dont' know my ass from my elbow in C), but could it be due to the fact that you're trying to point to a memory range with a single pointer? Perhaps see if pointing the pointer to the first array element brings you more success, or perhaps replacing the array of chars with a linked list.

arrays of chars are for strings.

lets see your declaration for your struct. is it a char * or a char [255]? it should be a char * because it needs to point to something, not have a buffer to be filled.

Also make sure your C++ strings are NULL-terminated

yeah i've had that problem before... why does my string foo show up as "foos@59iso9*%)(@(vjos9"?

[trieder]

Strings show up with garbage after them because they keep printing until they hit the termination character. So whatever garbled stuff you see after the string.... ONE character after that is the string termination character... Generally its \0

The following code will do pretty much what you want... however, if you want a default name of nobody, my suggestion is create a constructor in your struct (might as well make it a class if you do this) and allocate maybe 10 bytes of memory to the pointer, then set the name to the default...

#include<iostream.h>

typedef struct
{
char *name;
}PERSON;


int main(void)
{
PERSON bob;
bob.name = new char[10];
bob.name = "nobody";
cout << bob.name;

return 0;
}
