Run-Time Check Failure #2 - Stack around the variable 'ThetaMatrix' was corrupted.

[jack140494]

I have written this code to multiply rotation matrices together. However, I keep getting a "Run-Time Check Failure #2 - Stack around the variable 'ThetaMatrix' was corrupted." upon running. This has happened for almost all the matrix variables. I'm not sure what I do to fix this? (Sorry, I know the code is probably very poor).

#include <iostream>
#include <cmath>
#include <math.h>

{
double pi;
pi = 3.14;
product1[0][0] = cos(angle1*pi/180);
product1[0][1] = -sin(angle1*pi/180);
product1[0][2] = 0;
product1[1][1] = sin(angle1*pi/180);
product1[1][2] = cos(angle1*pi/180);
product1[1][3] = 0;
product1[2][1] = 0;
product1[2][2] = 0;
product1[2][3] = 1;
}

void BetaEntry (const double& angle1, double product1[3][3])

Your code performs several out-of-bounds array accesses. Just search for [3] to see them. Remember, an array with 3 elements uses indexes 0-2, not 1-3.
