For reading you use scanf() with format specifier "%f","%g","%e" or printf();
the variable tyoe is float and functions are in math.h

You need functions->read tutorials

What does fork() do? :?:

I want to have a class LIST -- a dinamic list of rational numbers (defined previously in my RATIONAL class). I want another class STACK to inherit LIST's root and end pointers for my list.(STACK also...

To Valmian: Comunicating functions are like:
class none
{
int x;
public:
int& getx()
{
return x;
}
};

How about:

#include <iostream.h>
#include <ctype.h>
#include <conio.h>
void main()
{
cout<<"please enter first name, middle name and last name"<<endl;
cout<<"(max 20 chars each)"<<endl;...

Well it's obvious you're using some sort of template or something I on't understand. To read text from a file use fgets(char *s,int nrchr,FILE *inpfile);
Since you're using fstream go for:
...

To Dave: Thanks a lot. I've figured out why it sometimes would work and other times it would crash! When a pointer is declared in main(), it has a residual adress to a memory block. Therefore, it can...

I've used them in a Snake game. I don't remember exactly but something like #77... :?: Check the ASCII code. You'll certainl find them there :)

Hmm how about declaring 2 macros:

#define max(a,b) a>b?a:b
#define min(a,b) a<b?a:b
int max,int min;
...
max=max(x[0],x[1]);
min=min(x[0],x[1]);
for (i=2;i<n;i++)
{

Are you sure? :?:
You will print "number of columns" times "$$". In nufanvandal's first post, I understood that a column is made up of a "$$" and a line is made up of a "$$", "number of...

TO Asif_NSU:I must admit that in Dev C++ this doesn't work at all. BUT in the DOS version it WORKS very well. I'm using Borlamd C++ 3.1. This thing is highly useful for ME. I will be in the 8th form...

ok i've written some code for you. it reads the number of rows and columns and prints the drawing.


#include <stdio.h>
#include <conio.h>
void main()
{
clrscr();
int m,n,i,j;...

Do you think it actually matters?!

If you have:


int a=new int[8];
a[0]=23;
delete a;
cout<<a[0];

Thx. I looked it up in a book.

BTW: Instead of using a vector: int a[100] you could use:

int *a;
a=(int*)malloc(100*sizeof(int)); OR
a=(int*)calloc(100,sizeof(int));


It's kind of...

ahh ok I see. Thanks Dave :)

Well, that's what his problem said. Anyway i'm not a US or UK citizen so i'm not great at english :sad: What is a vending machine exactly?! :o

I know they won't work in Visual C but I'm a Borland C++ (for DOS) user. :!:

How exactly do you want to get length?!!
The only way I know of is using <string.h> There is a strlen(char *s) function which return the strings length :D

Thanks Fire Net :D Do you suppose it's too late for it to be of any use?

ok... it's ready but it doesn't cover the part where the option is invalid ;)


#include <iostream.h>
#include <conio.h>
int dol,cen;
unsigned int cb=0,ch;
void convert(int cb)
{
...

I'm writing your program though it might be too late! ;)

There is a time structure you know-- see gettime() : :lol:

I have a very important question (for me)

How do i use <alloc.h>/<malloc.h>/<stdlib.h> for memory allocation?

i'm talking about: malloc(),calloc(),halloc(),realloc(),alloca(),heapwalk(),free()...

You're right Fire Net.

The colour list is ok. you know that's why i use printf/scanf

In <conio.h> you may find: cprintf(...);cscanf(...) with the same paramters as ...scanf() and...

Just asking Blood Night: What does output say?

what does 1n mean 1*n or 1n as a number; what do you mean???
( for all interested my e-mail is yuri@fx.ro-could you send answer here? )

It should be answer (b)
Here's an example:

#include <iostream.h>
main()
{
char s[100];
cin.getline(s,100);
cout<<s;
}

woops i'm from romania. "Numarul de termeni:" means how many elements you will input and "Suma obtinuta" means the sum you have obtained. My mistake! :o

well if you include main() in a header that would be more like a program than like a header but anyway you can ;)

Please give me all the details about your assignment-- exactly what must it do. I'd be more than happy to write a source file :p

Give me your e-mail and i'll send you the program! (it might be...

The answer is quite simple:
Just use "<"or">" operators in an "if" instruction like in a normal sorting method for numbers. Be careful though:
if you have:
...

Red_evolve... i've written a version for Q1 myself and it's pretty similar to yours (mine's a program---in my opinion you understood pretty good)

#include <stdio.h>
#include <conio.h>
long...

It is very very simple:


write some functions||define some macros||define structures/classes etc...
DO NOT include a main() function
save it with the name you want
e.g...

Well i'm a teen-ager myself (13). I recomend learning the PASCAL language then go to C. Pascal is far more basic; it doesn't have as many functions as C
BUT it is easier to use :mrgreen:

Ok--try this (i'm not sure it's perfect...13 yr olds can make mistakes)

#include <stdio.h>
#include <conio.h>
#include <alloc.h>
struct nod
{
int info;
nod *adr;
};
