C/C++ :: How To Store Big Values Either Int Or Floating Like PC Calculator
May 29, 2012
I just wanted to know how to store big numbers (like more than 20 digit values) in a variable?
For those type of big values, whether float variable is good or int variable is good?
And finally, all these challenges i am facing in the process of coding for an application which contains calculator and it should give the accurate results as our windows pc calculator.
Write a function named "sum" that takes as its arguments the following:
(1) an array of floating point values. (2) an integer that tells how many floating point values are in the array.
The function should return as its value the sum of the floating point values. For example, if the array that's passed to the function looks like this: 0 1 2 3 4 5.8|2.6|9.0|3.4|7.1
The function should return the value as 27.9 as its value...I know I need to declare and intialize the array in the main function. I don't how to write the sum function.
How to declare the values of the the dimes and quarters in my program. The purpose of it is to add up the total number in cents while at the same time making sure the program is universal to be used with different numbers.
Here is my code.
/*Take the number of dimes and quarters and get the total ammount of cents*/
#include <iostream> using namespace std; int main ( ) { int dimes,quarters,result,amount_1,amount_2 int result;
I am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage Strength = 2 grants +1 to hit and +2 damage Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.
I'm trying to read values from a file to store them in an array in C++ and then output the values in a table format for everyday of the month: morning, noon, evening and night. My text file looks something like this:
I serialize a XML file, and i have this values here:
public class ServiceConfig { public List<DatabaseDescriptor> Databases { get; set; } } public class DatabaseDescriptor { [XmlElement("Name")]
[Code] ....
I have a form1 which is a datagrid view and get's updated like this:
dataGridView1.DataSource = xmlData.Databases;
Now i have a button: get tables, and it opens up form 2, there it's supposed to appear all the tables of the selected Database, when i click on the row i get the database name so i get all the list of Tables from
DatabaseDescriptor where DatabaseDescriptor.Name == name (I get this when i select the row)
But then on the 2nd form, i also have 2 textbox so i add a new table, i add the tablename and id. the new value should appear in the datagridview of the tables, and when i close it and reopen it, it should be there. Maybe i should concatenate first the values or something, how do i do?
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.
5502 5202.3 1523 2536.1 1254 1256.2 17846 8956.2 and so on
left one is time and right one is pressure, I need to show the time value as it is but i need to use the pressure value to calculate air speed. I don't know how to use the strings to pick up the list properly. I did the calculation formula for the air speed but i can't pick the pressure value up from the text file. here's what i did:
#include <iostream> #include <fstream> #include <string> using namespace std;
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth. How I can accomplish this?
I want to store values permanently in a variable. The same variable should be able to be edited and saved by user, and whatever it is I need the value of the variable from the last time I modified it, like a database. database because i need this to set my connection string of the database.
My assignment is writing Madd Libs game. I still do not understand how to store inputted strings or values to arrays. I need explanation of collecting inputted data to arrays.
