    problem with my code

    i'm having a few problems with the code i've written. Th code presents a user with a menu, the user to enter a patient must select 'a' to allocate a patient and enter details. I'm currently working with the good ward only so the user must press 'g' when asked for ward condition. The details are saved in the appropriate array structure. The problem with my code is that when i select the view ward status option and then good ward 'g' to view the details entered, the data doesnt display from the array...can anyone help me on this please? thanks in advance

    void Patient::Allocate_Bed (void){
    int i,j,k;
    --------------------
    int main (void){

    Ward Hospital[13];
    Patient Details[13];
    char Option;
    int i, j;


    You never intialize i, j, k in Allocate_Bed(), nor i, j in main(), and since you never assign them a value, they contain junk values. (You should always initialize variables with 0 until you assign them a value.) So, in these lines:
    Code:
    case 's': Hospital[j].Bed_Status();
    	 		  break;
    		case 'a': Details[i].Allocate_Bed();
    	  		  break;
    		case 'd': Details[i].Discharge();
    	  		  break;
    Hospital[j] has an index that is some random junk value, and it certainly does not correspond to Details[i] whose index is another random junk value, and both will most likely be out of bounds; the indexes for Hospital and Details must be between 0 and 12. The compiler allows you to use indexes that are out of bounds, so you won't get a compiler error, but at runtime bad things happen, and the program will fail.
    Code:
    switch(Key){
    	case 'g':Good_Condition();
    		 break;
    There is no global function Good_Condition(). It's a class function and must be called on a class object, e.g.

    a_Ward.Good_Condition();
