Informatics - Run the Cash Flow Calculator Program (week 10)

Hi all! Here I am again making another post for you. As I promised last week on my previous post, I will show you how to run the Cash Flow Calculator program on windows. Are you excited? Let's run the program together! I will show you how to run it step by step. 

First step: The first step is open the folder you made for this program on your file explorer. Here, I put my folder on the documents. 

Here, I named my file as Cashflow Calculator. 

Second step: Right click then choose the "open in terminal" option. 
After you click the "open in terminal" option you will straight go to the Command Prompt. 

Third step: Type "g++ -c ./*.cpp" to compile the programs. If it succeeds you will go straight to the next step, then type "ls" to list the files in the folder. But if your program can't be compiled there will be "error" word on the command prompt, and it means that there's something wrong with your program. 
As you can see there, we don't have the .exe format file yet. The .exe file format stands for "executable," and its primary function is to launch or execute programs on Windows operating systems. 

Fourth step: Type "g++ -o CashFlowCalc ./*o" to link object files into a single executable file using the g++ compiler.  It links those files together to create a program you can run, mine is called CashFlowCalc.

After that, type ls again to list your files and there you go, we have the .exe format file. 

Fifth step: Type ".\CashFlowCalc.exe" to run the program to calculate the cashflow. 

Sixth step: Insert the value to calculate. 
Explanation:
- Input the discount rate (3%) for the cash flow calculations. Here I put 3% as the discount rate. 
- Input the time periods and the cashflow amounts.
      1  100: In year 1, there is a cash flow of 100.
      2  200: In year 2, there is a cash flow of 200.
      3  250: In year 3, there is a cash flow of 250.
      4  300: In year 4, there is a cash flow of 300.
- (-1) signaling that you have finished entering cash flow data.

Program outputs:
- Value25 : Possibly the discounted value of the cash flow in year 1.
- Same as Value25, Value12.5, Value 3.90625, and Value1.17188 are discounted cash flow values for subsequent years.
- The program sums up all the discounted cash flows to compute the present value, which is 42.5781.

Alright! That's all for the Cash Flow Calculator program. I hope it can help you to understand how to run the cashflow program. My next blog will be about me making a main cpp program to calculate all of the calculator that I have. So, stay tuned for my next blog! Thank you!.

Informatics - Making a Main C++ Program to Run all the Calculator Program (week 11)

Gambar
Hi everyone! So, in this blog I want to share to you about how I make a main C++ program to run all the financial calculator program. Financial calculator program is program that used to calculate financial problem based on users need. The goal of this program is user can calculate their financial problem by choosing one of the programs available.  There will be interest rate, compound interest rate, cash flow, and moving average calculator inside of this financial calculator. Notes: - Interest rate is the percentage charged by a lender to a borrower for the use of money, or the percentage earned by an investor on their money over time. It is expressed as an annual percentage of the principal amount. - Compound interest rate is the rate at which interest is calculated not only on the initial principal amount but also on any accumulated interest from previous periods. This results in the interest "compounding" over time, which can grow the total amount much faster than simple ...

Informatics - Triangles (week 18)

 Hi everyone! In this week I just want to show you some codes of how to make a standing up and also upside-down triangle. There will be some types of triangles here so stay tuned! 1. Right Triangle #include <iostream> int main (){     for (int i = 1; i <= 5; i++){         for (int j = 1; j <= i; j++){             std :: cout << "*";         }         std :: cout << std :: endl;     }     return 0; } This program prints a right-angled triangle pattern using asterisks (*). It uses a nested for loop, where the outer loop controls the number of rows (from 1 to 5), and the inner loop controls how many * are printed in each row. In each iteration of the outer loop, the inner loop runs from 1 up to the current row number (i), printing that many stars. After the inner loop finishes, a newline (endl) is printed to move to the next row. As a result, ...

Informatics - Making Minimarket Discount Program in C++ version 1 (Week 12)

 Happy new year all! 💥 I know it's pretty late but anyways I'm writing my first blog on this year. In this blog I'm going to share my assignment of making a minimarket discount program in C++. There will be two version of this program and here, I'm going to show you the first version. The purpose of this program is to check the total purchase amount against the specified thresholds to determine the applicable discount rate. It will also calculate the final price by subtracting the discount for the total purchase. As a reference to make this program, I was given a similar program.  // program GradeConverter.cpp #include <iostream> #include <iomanip> using namespace std; int main (){ int score; string grade; cout << "Please input numerical score (1-100):"; cin >> score; if(score <= 100){ grade = "A+"; } else if (score >= 80 ){ grade = "A"; } else if (score >= 70 ){ grade = "B"; } else if (scor...
