Help assigning memory to structure arrays
I need some help assigning memory to hold an array of structures with variable member arrays. Here is a part of the code
Code:
typedef struct
{
double *t_stp;
int *grid_id;
double *lv_x;
double *lv_y;
double *lv_z;
}AA;
int idx;
static AA *load;
if (idx == 0) {
load = new AA[idx+1];
}else{
delete [] load;
load = new AA[idx+1];
}
loadcase[idx].grid_id = new int[nc];
loadcase[idx].lv_x = new double[nc];
loadcase[idx].lv_y = new double[nc];
loadcase[idx].lv_z = new double[nc];
idx and nc are passed in. Depending on the value of idx nc can hold different values. I am sure the way I am assigning memory to structure load is incorrect. But not sure how to increment it based on the value of idx.
Please help!
