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...

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...

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>
