The Column Calculator Project is a C# console application that can read a CSV or TXT file with two columns of numbers and perform an operation of add, subtract, multiply, divide, exponent or round on each pair of numbers in the columns. The results are printed to the console.
- Microsoft Visual Studio or an equivalent IDE
- .NET Framework
The program source code consists of one class: Program.
This class is responsible for handling the user input, file reading, and calculation operations. The methods of this class are described below:
The Main method is the entry point of this console application and starts the program execution. This method includes a while loop that allows the program to continue executing until the user enters a key other than 'c'. Within the loop, the user is prompted to enter the file path and desired operator. The CalculateColumns method is called and passed these inputs.
The CalculateColumns method reads the CSV or TXT file and performs the desired calculation on each pair of numbers in the columns. The method then returns a list of calculated results. The value of filePathWithOperatorInput, which is passed from Main, is split into filePath and operatorInput. The validity of the file path and operator input are verified using the IsValidExtension and IsValidOperator methods, respectively. The pairs of values within the columns are saved to a pairs list, and the specified operation is performed on each using the appropriate method. The contents of the results list are printed to the console.
The Addition method adds the two numbers in each column.
The Subtraction method subtracts the second number in each column from the first.
The Multiplication method multiplies the two numbers in each column.
The Division method divides the first number in each column by the second.
The Round method rounds the sum of the two numbers in each column to the nearest integer.
The Exponent method calculates the first number in each column to the power of the second.
The IsValidExtension method is responsible for verifying the validity of the file extension. If the file extension is valid, the method returns true, otherwise false.
The IsValidOperator method verifies the validity of the operator input. If the operator input is valid, the method returns true, otherwise false.
