Try this farce ;-)

Who was your teacher?
This is good but can't understand head or tail of it in one go.

No you don't. It is for advice. I will give you final version before other.

will come to see response 7 min later.

What the hell had happened that this is not copying?
@Farce can I pm you my poetry again?

you want me to debug your program?

sure, PM me.

-F

Now I am using C++. So that farce can help me.

Of course tell me why array is not copying.

Try this farce ;-)

I am using C++ . Farce if you can tell me what is wrong with array copying I will use java.

Of course tell me why array is not copying.

can you try with 4 instead of xxx.length.

farce, are linux C and borland C the same ? with respect to syntax and all

Again getting this
a e i m
b f j n
c g k o
d h l p
class Math
{
public static void main(String[] args)
{

char[] charArray={'a','b','c','d','e','f','g','h','i','j' ,'k','l','m','n','o','p'};
char[][] char2DArray=new char[4][4];
char[][] a=new char[4][4];


int c=0;
for(int d=0; d<char2DArray.length; d++){
for(int b=0; b<char2DArray[d].length; b++){


char2DArray[b][d] = (char)charArray[c];

c ++;
}}



for(int i = 0; i <= 3; i++) {
System.out.print("");
for(int j = 0; j <= 3; j++) {
System.out.print(" " + char2DArray[i][j]);
}
System.out.println("");
}
System.out.println();
}


}

Situation solve ,able to copy now trying to produce as given

should be, I am not sure though.

In which line?

wow, i tho this question was only for integers, will try it out tomo

#line 1 "/root/mat.cpp"
/root/mat.cpp:1: error: Can't open include file "iostream.h"
#include <iostream.h>


int main()

{

char charArray[]={'a','b','c','d','e','f','g','h','i','j','k','l', 'm','n','o','p'};
char char2DArray[4][4];
char a[4][4];


int counter =0;




for (int column = 0; column < 4; column++) {
for (int row = 0; row < 4; row++) {
char2DArray[column][row] = charArray [counter];
counter++;
}
}
}
1 error in preprocessor.
Now what is wrong with using iostream.h?

Don't reply. should have use g++ compiler as have not link mccp compiler.

Somebody please explain about this !

usually the java programs i tried required me to have the "class name" and "file name" to be the same.

but i am able to run luke's program which starts with "math.class" from a differently named file.

confused !

javac Math.java
java Math

This program was for copying array only.

watever, now i made the program to work from java too !!

Don't know but g++ & turbo c++ are vastly different.

excellent, now go to the reverse puzzle.

Next in line after the reverse - write a program that prints itself
(no googling ;-)

sure, i ll try it tomo, no use in google, it kills the joy of programming

After a comedy of errors have to refer the book & found out some difference between g++ & turco c++:-
#include <iostream> no.h

int main()

{

char charArray[]={'a','b','c','d','e','f','g','h','i','j','k','l', 'm','n','o','p'};
char char2DArray[4][4];
char a[4][4];


int counter =0;




for (int column = 0; column < 4; column++) {
for (int row = 0; row < 4; row++) {
char2DArray[column][row] = charArray [counter];
counter++;
}
}

for(int i = 0; i <= 3; i++) {
std::cout <<std::endl;; no endl or cout simply
for(int j = 0; j <= 3; j++) {
std::cout<<char2DArray[i][j];
std::cout<<" "; }

}




}

I think I shouldn't copy simple here.

Want to curse my old teacher.

Programming Challenges - Steven S. Skiena
Will issue this book from my card. We can all solve the problems given in it. I think it is available in my library.
This start from basic level challenges. Can't purchase it as it will create a hole in my pocket.

Don't give answer.

Please don't post answers till 11pm 6 August.

Have to go to sleep.G'night. Also will go somewhere.

finished this in c++, java strings are giving me a headache

wow! I am impressed. How did you do it? don't post it here according
to Luke's request, maybe PM me.

well it was simpler coz, Turbo C is very lenient, doin in java is the real challenge.

Sent you PM.
