Consider these functions from the set of students in a discrete mathematics class. state under what conditions is the function one-to-one if it assigns to a student the following things below. also state how likely this is in practice. thematics blaue seate under what
(a) mobile phone number.
(b) student identification number.
(c) final grade in the class.
(d) home town.
for example, the function in part (c) is one-to-one if each student has a unique student identification number. in other words, if no two students share the same student identification number. this is usually the case in practice since identification numbers are usually used to identify a unique student.

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. the program should output the average high, average low, and the highest and lowest temper- atures for the year. your program must consist of the following functions: a. function getdata: this function reads and stores data in the two- dimensional array. b. function averagehigh: this function calculates and returns the average high temperature for the year. c. function averagelow: this function calculates and returns the aver- age low temperature for the year. d. function indexhightemp: this function returns the index of the highest high temperature in the array. e. function indexlowtemp: this function retur
