Question

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 temperatures for the year. Your program must consist of the following functions: 1. Function getData: This function reads and stores data in the two- dimensional array. 2. Function averageHigh: This function calculates and returns the average high temperature for the year. 3. Function averageLow: This function calculates and returns the aver- age low temperature for the year. 4. Function indexHighTemp: This function returns the index of the highest high temperature in the array. 5. Function indexLowTemp: This function returns the index of the low- est low temperature in the array. These functions must all have the appropriate parameters.
