Question

1) create a data file of the following structure (each represents the test scores of a class): the first two numbers are the number of students and the number of tests (integers), respectively. Then each row represents the test scores of a student. Each student's scores is in different row (it does not really matter if they are in different row or not, in fact.) Below is an example of an input file. You do not need to send me your input file. I will test your program on several different input files. 3 6 3.9 4.5 2.1 1.0 2.4 4.3 3.1 4.2 5.1 6.2 1.0 2.7 1.2 2.3 3.1 4.2 5.2 6.4 2) create a program that asks for an input file that has the structure described in 1). a) Read the data into a multidimensional (2-D) dynamic array of floats (by means of pointer and new). And: b) Compute and print the average (mean) test score for each student (you might label the student by 1, 2, 3, etc.) c) Then delete the pointer arrays by using delete function PROPERLY.

Explanation / Answer

#include #include//this is necessary for file in/out put #include using namespace std; //open a file with ofstream void createfile(){ ofstream outfile("testfile.dat"); //write data to file outfile
