i have a question is there any way that i can add up all the value in a multiplication table i create or parscal triangle i created? if yes i need to find out how to add up all values in a multiplication table. i can't figure out the logic behind how, its frustrating.

the code will be like this:

#include <iostream>
using namespace std;

int main()
int i, j, total;
for (int i=0; i<10; i++)
for(int j=0; j<10; j++)
cout << i*j;
total = i + j;
cout << total;
cout << endl;
return 0;

i know the above code doesn't work but i dont get it. why????????

First of all, please learn to format your code.

Are you trying to add all the i*j values together? If so, all you did is add the very last i and j values based on the loops. That's going to be 9+9 = 18. You need to add i*j to the running total. Something like total = total + (i * j) or thereabouts.

That code won't help you with Pascal's Triangle.

The computer is too stupid to help you do something. First figure out how to do it yourself, preferably with pencil and paper. Once you can do that, telling the computer how to do it is relatively easy.

you can do this in your mind

1*N + 2*N + 3*N + .... + (N-1)*N + N*N == 
          (1+2+3+...+(N-1)+N) * N == 
          ( ( N * (N+1) ) / 2 ) * N
