Answer :
The provided C++ code reads data from a file named "stem.txt" and performs calculations based on the data. It includes functions for opening the file and calculating ratios. The main function calls these functions and processes the file. However, the code is incomplete as the "ratioCalc" function is missing.
The program is intended to read data from the file and perform calculations on the data to generate ratios. The purpose of the program and the specific calculations to be performed are not explicitly mentioned in the given code.
The given C++ code is designed to read data from a file named "stem.txt" and perform calculations based on that data. It includes two functions, namely "openFile" and "ratioCalc".
The "openFile" function takes an ifstream object and a string (fileName) as parameters. It attempts to open the file using the given fileName. If the file fails to open, the function returns false; otherwise, it returns true.
The main function first declares an ifstream object (inFile) and a string variable (fileName). It then attempts to open the file "stem.txt" by calling the openFile function with the inFile object and the fileName. If the file fails to open, an error message is displayed, and the program terminates. Otherwise, it proceeds to call the "ratioCalc" function with the inFile object.
Unfortunately, the "ratioCalc" function is missing in the provided code. Therefore, the specific calculations and operations to be performed on the data from the file are not clear. Without the implementation of the "ratioCalc" function, it is not possible to provide a complete explanation of the code's functionality or purpose.
In conclusion, the given code is incomplete as it lacks the implementation of the "ratioCalc" function. Without the missing function, it is not possible to determine the specific calculations or operations intended to be performed on the data from the "stem.txt" file.
