Structure array problem

I made my own structure called person it consists of

Code:

struct person
{

	char personName[30];
	
	int amLevel;
	
	int noonLevel;
	
	int pmLevel;

};

Now I made an array of this structure called
person patient[25]
This I know limits the number of names I can put into the array to 25, but one name has everything that is in the structure. So when I call the program that has this structure and there is enough data to fill out 15 structures how can I only print out certain names with that name's info? or if there are many occurances of one name? Any help is appreciated. Thanks

So what I'm basically doing is this:

Code:

c:\>program  //This calls all the info and displays

c:\>programJohn_Doe  //This calls all occurances of that name 

c:\>programJohn_Doeam   //This calls all John Does and the am level

Well, you'd want to use spaces between those arguments, but if you know how to do this:

Then it's simple. Fill in your array, then have a loop that checks argv[1] against the values in patient[25].personName[x]. If it finds a match it outputs it. Also if argc > 2, then it can check the next argument against the appropriate variable, etc.

Now that helped a lot. Didn't think to use the argc and argv except in my switch statement. Appreciate the help. Thanks a lot.
