Thread: very weird error with a variable

heres a snippet of some of my code, but im getting a problem with the arrays that i've created..

whats going on is that i have a 2d array, and a 1d array
and say my 1d array has
2.
2.
3.
2.
2.
3.
2.
5.
0.
5.

what it should do is get each number and square it and put it in the 2d array. but it is not doing that. it does something weird like..

4
4
9
4
4
9
4 //works up to here and then the next 3 just stuff up
16
16
81

Code:

   int N = 5;
  int x, i=0;
    int number, row, column, new_col;

       array = (int **)malloc(N*sizeof(int));
       new_array = (int **)malloc(N*sizeof(int));
        bleh = (int*)malloc(N*sizeof(int));
 for(x=0; x<N; x++){   
                array[x]=(int*)malloc(N*sizeof(int));
                new_array[x]=(int*)malloc(N*sizeof(int));
        }

     for(row = 0; row<5;row++)
        {

                if(column>1)
                        new_col++;

                column = new_col;

                for(;column<=5;column++) //second for loop
                {
                        number = bleh[i];
                        array[row][column] = number * number;
                      new_array[row][column] = number * number;
                        i++;

                        printf("array is: %d\n", array[row][column]);
                        printf("new_array is: %d\n", new_array[row][column]);
                }

        }

any ideas?
im thinking that array and bleh are somehow linked mysteriously..

and the thing is when i insert a new variable like new_array it works.. its very strange..

yep bleh is set up somehwere else, the weird thing that is happening is that when i complete this bit of code

Code:

for(;column<=5;column++) //second for loop
                {
                        number = bleh[i];
                        array[row][column] = number * number;
                      new_array[row][column] = number * number;
                        i++;

                        printf("array is: %d\n", array[row][column]);
                        printf("new_array is: %d\n", new_array[row][column]);
                }

it changes the variables in the 1d bleh variable, when here i dont have anything that has bleh = ...

if i put in printf statements like so..

Code:

printf("gg1= %d %d %d %d\n", gg[6],gg[7],gg[8],gg[9]);

//above for loop goes here


printf("gg2 = %d %d %d %d\n", gg[6],gg[7],gg[8],gg[9]);

print out is

gg1 = 2 5 0 5
array is: 4
array is: 4
array is: 9
array is: 4
gg2 = 2 4 4 9
gg1 = 2 4 4 9

and so you can see that gg has changed??! it should stay as 2 5 0 5

really messy code..sorry

Code:

int main(int argc, char *argv[])
{
   FILE *input;
   int N, K, x, pos=4, b, s, r=0, q=0;
   int unequal=0, f=6, g, y=0, m, t;
   int **array=NULL, *bleh, **new_array=NULL;
   int *array;
   char *axe, *wax;
   int J=0, max = 0;
   int max_rows = 0, max_cols = 0, column=0, row=0, new_col;


  input = fopen(argv[1], "r+");
  fscanf(input, "%d %d", &N, &K);       
        axe = (char*)malloc(K*sizeof(char));    
       wax = (char*)malloc(K*sizeof(char));   
        new_array = malloc(N*sizeof(int*));
        bleh = malloc(N*sizeof(int));
 for(x=0; x<N; x++){   
             array[x]=(int*)malloc(N*sizeof(int));
                new_array[x]=malloc(N*sizeof(int));
        }

do
        {
                fseek(input, pos, SEEK_SET);   
                fgets(wax, K+1, input);           
                for(x=0; x<N-1; x++)
                {
                        fseek(input, pos+1+f, SEEK_SET);  
                        fgets(axe, K+1, input);
                        f+=K+1;
                        unequal=0;
                        for(g=0; g<K; g++)
                        {   
                                if(wax[g]!=axe[g])
                                        unequal++;      
                        }
                        bleh[q] = unequal;
                        q++;
                }
                pos+=K+1;    
                f=6; N--; y++;
        } while(y<=N+1)

        q=0;   t=1;
        max_rows = b; column = r; max_cols = s;
        row = m;   new_col = t;

//and then the for loops i already pasted go here
