7.5 Programming: Create and till array pased on input the Here's a realistic scenario where dynamically-allocated arrays are helpful. Suppose a file contains temperature readings, one per line. The first line of the file denotes the total number of readings. For example, here's an input file named "data1.txt" that contains 5 temperature readings: 5 41 38 21 39 43 Write a function named inputData that given a filename, dynamically allocates an array based on the first line of the file, and then inputs the temperature readings into the array. The function then returns a pointer to the dynamically-allocated array, along with the size of the array via a reference parameter named N. Here's the function declaration: int* inputData (string filename, int& N) {...} Notice the return type is int*, since the function returns a pointer to the array; the size of the array is "returned" via N. If the input file cannot be successfully opened, set N = 0 and return nullptr (do not output an error message, but instead return the value nullptr which signals that no array was allocated). The main program is written for you, and cannot be modified. The inputData function must be defined in "util.cpp" you select this file from the drop-down list above the editing window. You can test in "Develop mode" by clicking "Run my program", clicking anywhere in the terminal window, and then entering filenames such as "data1.txt" and "data2.txt. The main program will input the filename and then call your function. When you are ready to submit, switch to "Submit mode" and click "Submit for Grading". You have unlimited submissions; the system records your highest score across all submissions.
