Code Snippet Test

by theorangedog on Nov.04, 2007, under Skills

I installed the Code Snippet (codesnippet) plugin, so that any copied and pasted code looks nice.

A sample of a simple bond value calculator that I wrote a few months back is below:

  1. // this is a test to create a program that calculates bond prices
  2.  
  3. #include <iostream>
  4. #include <cmath>
  5.  
  6. using namespace std;
  7. double calc(double coupon, double numyears, double numpmts, double parval, double rdisc);
  8.  
  9. int main()
  10. {
  11.         double coupon, numyears, numpmts, parval, rdisc;
  12.         cout << “Enter the coupon payment: “;
  13.         cin >> coupon;
  14.         cout << “nEnter the number of years to maturity: “;
  15.         cin >> numyears;
  16.         cout << “nEnter the number of payments per year: “;
  17.         cin >> numpmts;
  18.         cout << “nEnter the par value: “;
  19.         cin >> parval;
  20.         cout << “nEnter your discount rate: “;
  21.         cin >> rdisc;
  22.         cout << “n”;
  23.  
  24.         calc(coupon, numyears, numpmts, parval, rdisc);
  25.  
  26.         cout << “nnOnly a sucker would pay more than that.nn”;
  27.         return 0;
  28. }
  29.  
  30. double calc( double coupon, double numyears, double numpmts, double parval, double rdisc)
  31. {
  32.         double rdiscbynumpmts, numperiods, value, pvfactor;
  33.  
  34.         rdiscbynumpmts = rdisc / numpmts;
  35.         numperiods = numyears * numpmts;
  36.         pvfactor = pow((1 + rdiscbynumpmts), numperiods);
  37.        
  38.         value = (coupon * ((1 - (1 / pvfactor))/rdiscbynumpmts)) + (parval * (1 / pvfactor));
  39.         cout << “The value of this bond is: “ << value;
  40.         return 0;
  41. }

And for the record, I realize that this may not be the most efficient code… its just an example.

    One downside of most syntax highlighters that do line numbering is that if you try to copy the code, you get the line numbers too.

    I think that was the primary reason I never used one on my site.

    Thanks for the tip, Alex. This one allows me to select whether or not the line numbers appear, and since I see the point in terms of copying, I’ll leave the numbers off in the future.

    No problem with the code because it was written in C++.
