I know that part. I did that. but it apparently does not work.

I have a code in which I want to swap an element in a matrix with another. User inputs the row, column no of the elements to be swapped. But the code doesn't seem to work. Can somebody help?
PS: The...

that works. thanks a lot!

nice idea. but how do I randomly shuffle a row? taking rowpos[]={0,1,2,3} how do I shuffle? using rand() won't work since I would have the same problem as before.

I know about the size of the array. I just put 10 so that the program doesnt eat up too much memory during testing. I'm pretty sure I decremented the value of n as well. something else is wrong.

for my project, I need to generate an n*n matrix (n is user input) with numbers from 1 to x (x<n) positioned randomly. I tried implementing it with this code but it doesnt seem to work. x = n*n -...

we have a project in our class to design a sliding numbers game similar to this one:

the only difference is that the number of blank spaces is...

Hey firenet
You had mentioned a way to delete a record from the file (using sequential access). I tried to do it with random access (i.e seekg and seekp). The program can't delete the last record....

I have a popup program that seems to have installed itself on my computer. Everytime my internet is idle, it displays search results from some searchmiracle.com. I don't know how it got onto my PC...

Since no one cared to answer my thread posted earlier, :mad: I'm posting the question again.
I have this project to do and I want to use coloured text and some simple shapes, etc. But the problem...

You don't HAVE to define NUM_TURNS as static. Defining it as static makes it common between all objects of that class. So if you have
GamePlayer a1;
GamePlayer a2;
then, a1.NUM_TURNS and...

No wait. You are trying to compare individual letters with strings when you use
words[i]. strcmp() can only accept string arguments.

Did you include string.h?

The remainder gives you the individual digit. After the remainder is taken, the no. is divided by 10. Since in int no decimal pts are allowed, the original no. has one digit less.
Then the remainder...

No comparison! I'm doing both subjects right now. And calculus drives me nuts! I mean its pretty awe-inspiring but it never gets into my head. C++ is a different matter. I thoroughly enjoyed every...

I have this project to do and I want to use coloured text and some simple shapes, etc. But the problem is that my compiler does not support graphics.h or dos.h. Even my tclite doesn't (I usually use...

You do have to use arrays in the method I know, but int arrays, not strings, which I think are easier to manipulate.

#include <iostream.h>
#include <conio.h>

int main()
{
int a[5]={0,0};...

Shalin's method is the ideal one. However, if you don't want to use strcmp() for some reason, there's always a manual, lenghtier way to do it:

#include <iostream.h>
#include <stdio.h>

int...

I don't get why C++ pros see red when they see void main(). Can someone explain why intmain() is good and void main() bad?

Well, you can try this code, but I don't know if it will work beyond n=9.

#include <iostream.h>
#include <conio.h>

/* This program creates a half pyramid of nos. Created on 12.6.2k3. */

Chainsaw's code is correct except for one thing, you add j to the sum, not i;

#include <iostream.h>
#include <conio.h>

void main()
{
int n;
cin>>n;
int i, j;

I didn't know I had to close all variables connected to the file to be deleted. It worked after I did that. Thanks a ton Dave. :)

I'm trying to use sequential binary file editing in C++. I use a temporary file. I have to make the changes in the file by storing the modified data in the temp file. Then I delete the original file...
