Stack around np

[confusedengstudent]

Im creating a program to solve a number pyramid, it reads in these numbers, it then Stores them in an array then displays the array except the -1's, in the shape of a pyramid. Then it solves as much of the pyramid as it can, then displays the pyramid again. it does this till all the zeros are gone. but whenever it does its first pass it messes the display up and "corupts the stack around np" which is the name of the array. Please help!

Within the loop on line 72:
Lines 74/77/80: I guess that it should be if?
Both i + 1 and j + 1 will be out ouf bounds when i/j are 6

[confusedengstudent]

Lines 74, 77, and 80, are if statements. Sorry about that, fixing it does not however solve the problem

[coder777]

The problem is this:

Both i + 1 and j + 1 will be out ouf bounds when i/j are 6

Change line 70: 6 -> 5 and 72: 7 -> 6

don't forget to remove the ; at the end of lines 74/77/80

That didnt fix it, some where in this code:

//solver in the while loop
		for (i = 6; i >= 0; i--)
		{ 
		for (j = 0; j < 7; j++)
		{
			 (np[i][j] != -1 || np[i + 1][j + 1] == 0 || np[i][j + 1] != 0 || np[i][j] != 0);
			 np[i + 1][j + 1] = np[i][j + 1] + np[i][j];

			 (np[i][j] != -1 || np[i + 1][j + 1] != 0 || np[i][j + 1] == 0 || np[i][j] != 0);
			 np[i][j + 1] = np[i + 1][j + 1] - np[i][j];			 

			 (np[i][j] != -1 || np[i + 1][j + 1] != 0 || np[i][j + 1] == !0 || np[i][j] == 0);
			 np[i][j] = np[i + 1][j + 1] - np[i][j + 1]; 
		}
	   }

its causing all the negative ones to be changed to negatve 2's as which cause the display to be messed up, as for the stack corupting i have no idea
