Cuya - Performance Task 2

Reflection

For this activity, I tried to improve the alignment much more in order to have more freedom on how to display information in the console. In this case, the border(), centerX(), coutxy() and spacer() functions are an attempt to solving this problem, which made designing much easier than before. (I wouldn’t have to manually type spacing unlike before).

This was also the first time that I used loops based on input. In Employee Detail Input, the screen is embedded in a do-while loop. After the department code has been placed, the code checks it and if it recognizes the code, it assigns a value for the department that can then be used when displaying the payroll.

One major problem I encountered is when working with strings. When coming off from JavaScript where strings are much easier to manipulate, I had to do some more digging for it to to actually make it work. Strings in C++ are just arrays of characters and it is very different in how I used to handle strings like it was in JavaScript.

Explanation

The code uses the following header files:

• string.h
  • strlen() used in centerX() to find the numerical length of the given string, which is used to center the string itself.
  • strcpy() used in Employee Detail Input to store strings in a variable.
  • strcpy() and strcat() used to combine strings in Employee Payroll to be displayed in the console.

The code uses several user-defined functions.
(Function definitions are in the code before the main() function definition.)

• border(x1, y1, x2, y2, char)
  • It is a function that displays a rectangular border in console using a character of user’s choice using two points in space.
  • The rectangular border should have the vertices (x1, y1), (x1, y2), (x2, y1), (x2, y2) in the Turbo C++ console.
• centerX(string)
  • It is a function that returns an integer value that can be used to center the string input when used with gotoxy().
• coutxy(x, y, string)
  • A function that displays a string input on a specified location in the console.
  • Can only be used to display string literals.
• spacer(x)
  • Adds spacing until the cursor reaches a specified point in the horizontal direction, which can be used primarily to align values in console.
