Thread: malloc 2D array

hi all

I am using the following code, which is printing a value of 0.0 instead of 212.0. What am I doing wrong?

Code:

double **u;
int N = 52;
int i;


u = malloc (N * sizeof(double *));;
for (i = 0; i < N; i++)
    u[i] = malloc(N * sizeof(double));

u[10][10] = 212.0; 

printf("U[10][10] = %4.3f", u[10][10]);
