Interesting Task

[Vlatko]

Write the code which will print out this


1
232
34543
4567654
567898765
67890109876
7890123210987
890123454321098
90123456765432109
0123456789876543210

And nicely formatted as well:

#include <iostream>

using namespace std;

int MyTrunc(int iNum) {
	int temp = iNum;
	while(temp >= 10) temp -= 10;
	return temp;
}

void DrawPyramid(int iMaxOuter) {
	for(int i = 1; i <= iMaxOuter; i++) {
		for(int j = i; j < iMaxOuter; j++) {
			cout << " ";
		}

		if(i == 1) {
			cout << "1";
		} else {
			for(j = 0; j < i; j++) {
				cout << MyTrunc(i+j);
			}
			for(j = i-2; j >= 0; j--) {
				cout << MyTrunc(i+j);
			}
		}
		cout << endl;
	}
}

void main() {
	DrawPyramid(10);
}

Cool parksie!

[parksie]

I already had that code stashed away because I got a question for that emailed to me through AllExperts

[Vlatko]

I was looking at some old C book from my uncle and saw some pyramid stuff. This seemed very interesting and so i posted it..

Write the code which will print out this

cout << "1" << endl;
cout << "232" << endl; 
cout << "34543" << endl; 
cout << "4567654" << endl; 
cout << "567898765" << endl; 
cout << "67890109876" << endl; 
cout << "7890123210987" << endl; 
cout << "890123454321098" << endl; 
cout << "90123456765432109" << endl; 
cout << "0123456789876543210" << endl;

You didn't specify how

[parksie]

You're such a cheeky git, Megatron

Nice attitude tho

[Vlatko]

cout << "1" << endl;
cout << "232" << endl;
cout << "34543" << endl;
cout << "4567654" << endl;
cout << "567898765" << endl;
cout << "67890109876" << endl;
cout << "7890123210987" << endl;
cout << "890123454321098" << endl;
cout << "90123456765432109" << endl;
cout << "0123456789876543210" << endl;

I knew somebody will post that

How does your function work, Parksie? )just dont get it

[parksie]

I don't know...I wrote it quite a while ago -- try stepping through it with the debugger.

ok
