i want to delete an element of array structure to use it again to more understand look to the part of this code

struct patient

{
	int ID;
	 char name[100];
	 float age;
	 char sex[7];
	 char adress[100];
	 char hometelephone[12];
	 char mobiletelephone[11];
	 char workingtelephone[12];
	 char date[12];
	 char time[13];

} patients[100];
void delet()
{
int ida;
cout<<"Enter your Id"<<endl;
cin>>ida;
/* i want to delete this patient
patients[ida].name=0;
patients[ida].age=0;
patients[ida].id=0;
patients[ida].sex=0;
patients[ida].hometelephone=0;
patients[ida].workingtelephone=0;
patients[ida].mobiletelephone=0;
patients[ida].date=0;
patients[ida].time=0;
*/
}

Can you use vectors or stacks?

Either move all other patients down one position or make an array of pointers to patients and allocate them dynamically. Then you can delete the patient at a certain position and mark the position as free by setting the pointer to 0.
Since your array seems to play a double role of also acting as a id->patient map, the latter is probably the better solution.

Of course, you could just use a real map.
