Writing your first program in C++

Follow the steps givcn in the link below:

https://tutorials.visualstudio.com/cpp-console/create.html

Then, modify the code as shown below:


# include <iostream>
using namespace std;

int main()
{
	cout << "This is my first C plus plus program";
	return 0;
}

Explanation of code

Line 1 of the code instructs preprocessor to includes input/output stream header file in the program.

Line 2 instructs to look at a the namespace std which has iostream file

Line 4 start of main function. This is the entry point into the c++ program. Note that in line 5 the function body starts with a { and it ends in line 8 with a }. Within the main functions's body block all statements ends with a semicolon ";" .

In Line 6 cout, pronounced "see out", sends the message to the standard output or computer screen.

CUMIPMT and CUMPRINC function

CUMIPMT Cumulative interest payment function allows you to calculate the interest paid for a loan or from an investment from period A to period B. When getting a loan, CUMIPMT function can be used to calculate the total amount of interest paid in the first five months or from period 12 to period 20. A period can be a month, a week or two week. Loan Amount : 350,000.00 APR: 4.5% Down payment: 0.00 Years: 25 Payment per year: 12 From the above data, we can calculate the following: No of Period: 25 × 12 = 300 Periodic Rate: 4.5/12 = 0.375% Here is how you will substitute these values into the function. = CUMIPMT (periodic rate, No of period, vehicle price, start period, end period, ) = CUMIPMT (0.375, 300, 350000, 1, 5, 0) In an excel worksheet, we use cell address instead of actual values as shown below: Here is the formula view of the worksheet: CUMPRINC Another related function is CUMPRINC. CUMPRINC function is used to calculate cumul

Excel PMT Function

PMT function is very useful for calculating monthly payment required to payback a loan or mortgage at a fixed rate. This function require a minimum of three inputs, periodic rate, number of periods, present value or the loan amount. Here is a simple example. Home Loan: 350,000.00 Interest rate: 4.5% Number of years to repay the loan: 25 Note: To calculate monthly payment, we need to find the monthly rate and number of months as shown above. Then it is simply a matter of substituting the values into the payment function, as shown in the formula view below.

BCG's Brand Advocacy Index

The Boston Consulting Group's (BCG) Brand Advocacy Index (BAI) is a metric developed to help companies measure the degree of customer advocacy for their brands. BAI focuses on the likelihood of customers to recommend a brand to others, which is a powerful indicator of brand strength and customer loyalty. Unlike other customer satisfaction or loyalty metrics, BAI emphasizes the importance of customer referrals and word-of-mouth marketing. BAI is calculated based on a survey where customers are asked about their willingness to recommend a brand to their friends, family, or colleagues. The responses are then used to compute a score, which ranges from -100 to 100. A higher BAI score indicates that a brand has more advocates who are likely to recommend the brand to others, while a lower score suggests that the brand has fewer advocates or even a higher number of detractors. BCG's research has shown that companies with higher BAI scores tend to experience higher growth rates and bett
