C++ :: Program To Display Percentage Of Calories Come From Fat
Mar 18, 2013Write a program that asks the user to enter the number of calories and fat grams in a food item. The program should display the percentage of the calories that come from fat. One gram of fat has 9 calories, so:
(Calories from fat) = (fat grams) * 9
The percentage of calories from fat can be calculated as:
(Calories from fat) / (total calories)
Extend as follow
1. The user first enters from a menu whether it is breakfast (B or b), lunch (L or l) or dinner (D or d). Use character and process by a switch.
2. The threshold for low calorie is different, for breakfast 10%, lunch 20%, dinner 30% (this value has to be assigned to some threshold variable in the above switch).
3. Include validation of menu choice.
4. In case any validation fails, display detailed error and exit the program by calling return 1 or return EXIT_FAILURE
5. Display the % from fat with one decimal digit.
Example 1:
What you have to eat:
B - breakfast
L - lunch
D - dinner
What you have: C
Error: C is not a valid menu choice
Example 2:
What you have to eat:
B - breakfast
L - lunch
D - dinner
What you have: L
How many calories: 600
How many grams of fat: 10
Your food has 15.0% calories from fat
It is a low calories food
Process the menu in a switch, setting the threshold as either 10, 20, or 30%. The rest of the program will be the same regardless what was the menu choice.
Incremental development: first do the textbook problem without input validation, then extend with validation, then extend for the additional parts.
C# :: Constant Read CPU Percentage And Display It To Textbox?

Jan 16, 2014I am writing a piece of code that requires me to display the last 1000 lines from a multiple text files (log files). FYI, I am running on Linux and using g++.
I have a log file from which - if it contains more than 1000 lines, I need to display the last 1000 lines. However, the log file could get rotated. So, in case where the current log file contains less than 1000 lines, I have to go to older log file and display the remaining. For e.g., if log got rotated and new log file contains 20 lines, I have to display the 980 lines from old log file + 20 from current log files.
What is the best way to do this? Even an outline algorithm will work.

C/C++ :: Create Program To Calculate A Percentage For Commission And Bonus?
Feb 11, 2014I am using codeblocks for school and I am trying to create a program to calculate a percentage for commission and a bonus. I have tried using a decimal for percentage, int and floats with casting. Every time it I try it displays 0 or just the bonus. I even took and did a test page. My head is about to pop.
Write an algorithm that can be used to calculate the commission earned in a real estate transaction. The chart below describes the formulas used to calculate the commission.
Sales Price Commission
Less than $100,000 5% of Sales Price
$100,000 to $300,000 $5,000 + 10% of Sales Price over $100,000
More than $300,000 $25,000 + 15% of Sales Price over $300,000
// Commission and Bonuses.

C++ :: Dice (with Varying Number Of Sides) Program To Calculate Percentage Of Results
Oct 28, 2013I am trying to code and compile a program that requests a uses to first inpu the number of sides they wish for a dice to have and secondly input the number of dice throws they would like to calculate the value for. The program will print an error message and default the number of sides the dice has to 5 if the number entered is below 4. Finally it will print out a percentage figure for each value that results from all the the dice rolls.

C++ :: Vector Comparison Out Of Range?
Jul 31, 2013I'm making a simple game and I'm having trouble creating boundaries for the players movements. The map is a 2D vector. When I compare the vector with the players current position sometimes I get an error during run. When the error isn't occurring the behavior of the boundaries is bizarre. The error tells me that the vector is out of range.
Here is the where the map is created. It's within its own class constructor.

C++ :: Sorting A Map By Custom Comparison?
Jan 8, 2012so i have a std::map like this:
map<DWORD,DWORD> mymap;
now i want to sort it by the second DWORD value, and thus i have to implement my own comparison function and use sort() from <alogirthm>:
Code:
bool y(const map<DWORD,DWORD>::iterator& a, const map<DWORD,DWORD>::iterator& b)
{
if(a->second < b->second)
return 1;
else
return 0;
}
...
sort(mymap.begin(), mymap.end(),y);

but this throws thousands of errors at me, including C2784.
C++ :: Comparison Of Two Strings (case Insensitive)
Apr 27, 2013bool simpleQuestion::checkAnswer(string guess) const {
for (int i=0;i<qAnswer.length();i++)
if (qAnswer==guess)
return true;
else
return false;
}
This is my code and what im trying to accomplish here is making the comparison of the two strings (qAnswer & guess) case insensitive. I know i need to loop through each character of each string and for each character i can use toupper and every char in each string will become uppercase and therefore case insensitive. However, im not sure how to go about this; if any technique used to loop through each character of the string and how to use to upper.
