pointer to array of structures 1

[AQWQ]

Dear all,

I need to know the how do i allocate memory to structure array dynamically.I tried this but couldn't help me..

struct A{
int i;
};

void main()
{

struct A *a1;
int i;
for(i=0;i<10;i++){
a1=(struct A*)malloc(sizeof(struct A*));
}
}

when i tried to compile this it threw some error..wud appreciate if someone could help me!!

Thanx in advance, Santhosh Ravindran

Try this:

struct A{
int i;
};

void main()
{

struct A *a1;
int array_size=10;
a1 = malloc(array_size*sizeof(struct A))
}

try using calloc.

 

[michaelkrauklis]

struct A{
  int i;
};

void main(){
  struct A *a1;
  int array_size=10;
  a1=(A*)calloc(array_size,sizeof(int));
}

//that should do it, although the int might not be what you
//are looking for.  sizeof(A) should work but I remember
//that can be a bit quirky.
//here is the function documentation for calloc
void *calloc( 
   size_t num,
   size_t size 
);

//whenever dynamicaly allocating an array calloc is the way
//to go

//GOOD LUCK!
