C++ Patient Sorting Algorithm: Prioritizing Elderly Patients

The given code is written in C++ and it sorts a list of patients based on their age and identification number.

Explanation of the code:\

• The code defines a structure named "patient" which has three members: "id" (string), "age" (integer), and "ord" (integer).\
• It declares an array of patient structures named "p" to store the patient information. \
• It defines a comparison function named "cmp" which compares two patient structures based on their age and ord values. \
• The main function reads the number of patients (n) from the user. \
• It then reads the id and age of each patient and assigns them to the corresponding elements in the "p" array. \
• The "sort" function is called to sort the "p" array based on the "cmp" comparison function. \
• Finally, the sorted list of patient ids is printed.
  
  Overall, the code sorts the list of patients in descending order of age, with the patients above 60 years old appearing first. If two patients have the same age, they are sorted based on their ord value (identification number).
