Is Linking array content with a string possible?

[Wagari]

I am trying to write a code for a simple calendar/to-do list program which prompts the user to enter the desired month, and when the user does so, the calendar for the selected month comes up on screen. next, the user enters an appointment for any date of that month and then his appointment is stored in a string linked to that date. The date then turns into a different shade of color to show that it has a linked appointment. I am strictly limited to arrays and strings, not even allowed to use structures or functions. I got stuck at linking a date with a specific appointment, how do I do this? do I need to allocate dynamic memory for every appointment? Here is the code, any help would be greatly appreciated.

  #include<iostream.h>
#include<conio.h>
#include<string.h>
#include<process.h>
void main()
{
	clrscr();
	int month,day[31],date;
	char note[100],response;
	cout<<"Enter the month of 2015 you would like to access:\t";
	cin>>month;
	switch (month){

	   if(i==5||i==12||i==19||i==26)
