Give me an example of deep copy and shallow copy of the structure. (C-Language)

The structure is made by the following function:

struct Double_Array {

double **array;

int rowsize;

int colsize;

};

struct Double_Array *double_array(int row, int col) {

struct Double_Array *ptr = malloc(sizeof(struct Double_Array));

ptr->array = malloc(sizeof(double *) * row);

for (int i = 0; i < row; i++) {

ptr->array[i] = malloc(sizeof(double) * col);

}

ptr->rowsize = row;

ptr->colsize = col;

return ptr;

}

void randomize_array(struct Double_Array *ptr, double row, double col) {

for (int i = 0; i < row; i++) {

for (int j = 0; j < col; j++) {

ptr->array[i][j] = rand_double(0.0, 10.0);

}

}

}

int main(){

int row = 6;

int column = 9;

struct Double_Array *a1;

a1 = double_array(row, column);

randomize_array(a1, row, column);

}
