Hi.
How can I assign an structure with values in its fields name=doom
memory=1212, time=12, files=2; but dinamically???
so i use malloc sixe of


the list does not begin in NULL instead "doom"
i have a menu that insert a new Node, when you press F1
printinscreen when you press F2,
SO WHEN I PRESS F2 I WANT THAT THE PROGRAM SHOWS

DOOM
1212
12
2

HOW CAN I DO IT???????????????????????????????


I KNOW THAT the structure has the fields:

struct proceso{
char name[20];
char memory[10];
char time[10];
char files[10];
};

and I HAVE TO USE

strcpy( ????->name = Doom3;
strcpy( ?¡???->memory=1212;
strcpy( ?????->time=14;
strcpy( ????->files=2;

BUT HOW?


PLEASE HELP ME, WHEN I PRESS F2 I WANT TO SHOW
DOOM AND OTHER FILEDS, SO THE LIST FIRST ELEMENT OF THE LIST IS DOOM, NOT NULL


I have done this:

#include <conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define F1 59
#define F2 60
#define ESC 27

struct proceso{
         char name[20];
         char memory[10];
         char time[10];
         char files[10];
           };

struct Node{
       struct proceso info;
       struct Nodo *next;
       };

why did you not post function insert() ? Is that the function you have the question about?

if you want to copy one structure into another you can use memcpy() function to copy everything in one bang.

it is possible you could use a default constructor to set the fields of your object:

struct proceso
{
    char name[20];
    char memory[10];
    char time[10];
    char files[10];

    //constructor
    [b]proceso();[/b]
};
//Function Definition
proceso::proceso()
{
    strcpy(name = Doom3);
    strcpy(memory = 1212);
    strcpy(time = 14);
    strcpy(files = 2);
}

The constructor will set the according attributes for each new creation of an instance of the 'proceso' object.

that constructor is totally wrong. you need to compile code before posting to make sure it will work.
