You have to expect the following input : an arbitrary amount of lines, each line consists of 5 int32 numbers. The full input will be terminated by an EOF.
E.g.:
1 2 3 4 5 6 7 8 9 0 ...
You`re then supposed to convert the numbers to integers and do some calculations. I would know how to parse a single line of 5 numbers via scanf(). That`s easy, and that`s exactly what they did in class.
But how do i go about splitting the lines? What about the EOF? Even if could hack something together, by using errno or something, it would be way beyond what they are doing atm. The input is received via user input, ie stdin.
I've written a simple program, which asks the user to respond to a YES or NO question using the character Y/y for YES and the character N/n for NO. The foundation of this program is based around several IF statements implemented to aid in finding the ASCII value of the character entered before invoking the corresponding cout statement that informs the user which character they entered. My Question: How should a program be written to deal with ignoring case sensitivity in regards to the users' input?
Here is my amateurish attempt,
Code: #include <iostream> using namespace std; int main()
[Code] .....
The following are IF statements written for the program to determine whether the user answered YES or NO. The program then performs the cout statement that contains the corresponding character to the ASCII value found.
I'm writing a program that writes to a report in a text file. It uses a struct but with no array. How can I write this so that the report comes out as it should because as of now after i removed the brackets from record which is the variable of the struct my report isn't printing right.
I have the text parser done, but when I use it, the program crashes. Just because of how I test my code, I know the section where it occurs, but I'm not sure what the exact problem is ( no errors or warning, so it's just something I don't see ). Here is the full code
I probably made a mistake in the way I allocated memory or tested values, but I'm not sure where it is in my code. Currently it just prints out "Failed to parse data on line 1" then crashes. Here is the text file I give to this program.
I have a txt file of drinks, and I want to meak a list of buttons of it (the txt file is build like this: fanta : 2 ), how can I make buttons of all the drinks ( I get the first one in a button , but not the others).
Dictionary<string, double> drank = new Dictionary<string, double>(); string[] words = new string[8]; Button button; <Button> BtnList = new List<Button>();
i have an xml which is in showing in multilines and the tags are not in single line and are discontinued in next line .I need to this xml to be in correct format and want to display as xml .
i want to convert the Digits in words.I have already a code but in my code the value is coming like for ex:-540000(Five hundered and Fourty Thousand ).but i want Five Lakh and Fourty thousand.
i create two forms add a password in first form throgh user input and second form will open i want that password will automatically be added to second form. first form is ok working according to my expactations but problem that it does not enter pssword in second form i reference that textbox that is
stdfrm std=new std(); std.a=txtpwd;
it displays an error that cannot implicitly convert type system.windows.forms.textbox to string
I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.
i want to know how to copy data from already written text on console?
i am actually making a program that reads texts already printed over console so i want to capture that data again but i must not have a copy version of every thing behind the scenes i.e. in the background. I need to know how to capture data or amount of some data from console output? for example:
[console started]

Now i have no copy of any data printed on console/command prompt or whatever you say it. My question is how can i copy following strings from console?
1) It's imaginative console for the purpose of understanding.

I'm taking an operating systems class and I'm trying to write a script that would execute a program in Simple OS.I"m not sure if this is the right place for this because although the entire OS is written in C, "asm" are assembly language code. Anyway when I run the OS in virutal box and try to run a program, I get a "Fatal Execption" in a loop until the entire OS crashes. So then I try to debug my code BUT when I add printf statements and try to run the code again I don't get to the "fatal execption" and the entire OS just crashes. 1) why can't I add print lines? 2) what's going on with the fatal execption?

Here is a working C++ program and its output that reads the names of a certain number of functions whose names are written in a disk file that provides the control parameters in a near-real time fashion. Based on this information, the program calls those functions whose names were given in this text file as parameters. The method I have used is to build a map of functions that connects the names of the functions to the actual functions. Once this map is created, then it is very easy to iterate in such a way that only those selected functions are called.
So far this is working well, and it makes the logic of the code easier because ultimately there will be a large inventory of functions (probably hundreds of functions), and this way of pre-building a map of functions avoids writing hundreds of if statements in the code. Of course, pre-building this reusable map in the background is still equivalent to writing that many if statements, but at least it makes the code very compact and much more automatic, since it is done only once.
But I now have a related question: In this case (when the selected subset of functions to call is given as incoming data as in this example), does C++ make it possible to avoid using maps of functions, by directly applying the string variable that holds the name of the function in order to call the original function immediately For instance, if a string variable s = "MyFunction", then is there a more direct way of using this string as if it were the actual function whose name is spelled exactly in that way? This would make the code even more compact.
Here is the sample test code for the map of functions, and its output:
First of all here is the text file "FileForNamesOfFunctions.TXT" that contains the part of the "data", which is the set of functions select from from the inventory and only call these:
Code: function2 function3 function5 And here is the C++ code that uses this "data":
i cant display the data written to this file in a switch statement (case 2) what am i doing wrong..the file data is being written into the text file but i cant display it
I've found that with streamwriter(sw) the data isn't displayed with the written to document until you either leave scope or use sw.close I'd prefer to keep sw open as I will be writing to the file in and out, sometimes very frequently, but would also prefer the data to be viewed in real time. Is there an efficient way of going about this?
I am trying to write a client/server application that takes input to an array of structures from the user,stores the data in a shared memory segment and then writes the same to a file when I close the application. How do I get started? And how do I ensure that the server stores the data correctly? Also, the server needs to be a concurrent server that accepts connections from multiple clients.
I made this program to convert bits to bytes, because I'm so sick of seeing ISP's advertise speeds in megabits, which I consider an intentional attempt to decieve :P And I think I've finally understood how the return value of scanf works since the last time I posted here, so my program can check to see if an integer was entered before processing the input, but I'm stuck on how to make the whole program start over if an integer is not entered. I have a hunch it would involve a loop, but I can't figure out how to make the program start over at "How many mb do you need converted?" if an integer is not entered into scanf..Here is the code I have so far:
Code:
#include <stdio.h> int main () { int b, mb, kb, Byte, kB, mB, gB; char term; }
[code]....
and my program makes the assumption for now at least, that mb will be inputted because that's the unit of measurement that i usually see advertised, and i didn't bother making an if statement to print a conversion in terms of gigabytes because i've never heard of a connection that fast :P
(Program) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet.
b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data.
here is what have so far
#include<iostream> #include <iomanip> using namespace std; // a programs to convert meter to feet int main() { const int MAXMETER = 10;
[Code] ....
I don't know how to have a setup where you input the values, and then will be provided the output.
