MISCUE!! How do I do this????

[Zumina]

I need to write a program hat prints the following multiplication table using while loops; and no if statements:

1 2 3 4 5 6 7 8 9
1 1
2 2 4
3 3 6 9
4 4 8 12 16
5 5 10 15 20 25
6 6 12 18 24 30 36
7 7 14 21 28 35 42 49
8 8 16 24 32 40 48 54 62
9 9 18 27 36 45 54 63 72 81

I'm stumped! My while loops produce garble; as they only carry out the first two numbers.....please please enlighten me!

In C++ ? VB ?

I Might be able to help.

int row=1;
int column=1;
while (row<10)
{
column=1;
while(column<=row)
{
cout << row*column << " ";
column++;
}
cout << endl;
row++;
}

that's in c++. pretty sure it works. try it. oh doesn't print out your 1-9 at the side and bottom though. just noticed that. if you can't figure that out you don't belong in computer science.

#include < iostream.h >

#define MAXTABLE 9

int main()
{

cout << " ";
for (int i = 1; i <= MAXTABLE; i++)
cout << i << ' ';
cout << endl;

for (int j = 1; j <= MAXTABLE; j++)
{
cout << j << ' ';
for (int i = 1; i <= j; i++)
cout << i * j << ' ';
cout << endl;
}

return 0;
}

I just noticed you wanted while loops. Same thing really, just create a for-loop using while.

Thanks Guys!!!! *bows head in the presence of computer gurus*

[Zumina]

wait a minute....no For loops allowed!!
this is funky:

code:


#include <iostream.h>

int main(void)
{

int row=1;
int column=1;
int test = 1;

cout<<" 1 2 3 4 5 6 7 8 9" << endl; //yah, I'll add some iomanip late
while (row<10)
{

column=1;
while(column<=row)

{
cout << row*column << " ";
column++;
}

cout << test <<" "<< row <<" "<< column << endl;
row++;
test++;
}

return 0;

}

output:
1 2 3 4 5 6 7 8 9
1 1 1 2
2 4 2 2 3
3 6 9 3 3 4
4 8 12 16 4 4 5
5 10 15 20 25 5 5 6
6 12 18 24 30 36 6 6 7
7 14 21 28 35 42 49 7 7 8
8 16 24 32 40 48 56 64 8 8 9
9 18 27 36 45 54 63 72 81 9 9 10

grrrrr!

up!

[gimp]

to change the for loop to a while loop, just do something like this:
j=MAXTABLE;
while(j>=1){
blah
blah
blah
j--;}

[Zumina]

what is this maxtable business?

[MantisMag]

what's with that test? that cout statement is all screwy. MAXTABLE is just a constant. although i was told that doing it that way was bad style. shouldn't use define cause that's c not c++. i'm gonna help you out here and fix your code. i don't know what the hell you were thinking with that test thing.

#include <iostream.h>

void main()
{
int row=1;
int column=1;

cout<<" 1 2 3 4 5 6 7 8 9" << endl; //yah, I'll add some iomanip late
while (row<10)
{

column=1;
cout << row << " ";
while(column<=row)

{
cout << row*column << " ";
column++;
}
cout << endl;
row++;
}
}

i even compiled it and ran it and got this output:
1 2 3 4 5 6 7 8 9
1 1
2 2 4
3 3 6 9
4 4 8 12 16
5 5 10 15 20 25
6 6 12 18 24 30 36
7 7 14 21 28 35 42 49
8 8 16 24 32 40 48 56 64
9 9 18 27 36 45 54 63 72 81
Press any key to continue

ok? got it? any questions now? like i said i have no idea what you were thinking with that whole test thing. that cout screwed everything up.

[Zumina]

doh! Why, why are the answers so painfully obvious? Gimp, thank you SOOO much! I apreciate it. Sorry for looking like a C++ fool, but I'm just starting and I've never really understood while loops and such; until now. Thanks man!
