C++ :: How To Get Code To Read Multiple Input Values
Feb 10, 2013
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1520 1730
[1520<1730]
Enter two times in military format (e.g., 1730 1520): 1730 1730
[1730==1730]
Enter two times in military format (e.g., 1730 1520): 1760 1520
1760: [INVALID TIME 1]
Enter two times in military format (e.g., 1730 1520): twelve 2
[INVALID NUMERIC INPUT]
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.
write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
I have a C++ code reading large data from an input txt file, doing some calculation on the data, and writing the result of calculation in another txt file.
I have about 300 input files, and the calculation time for each input file is pretty long (~4 days on a single CPU), so I would like to run the same code on multiple CPUs for different inputs.
Which is the most appropriate strategy in this case, multithreading, mpi or something else?
I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() { double a = 1.5; double b = 2.5; double c = 3.5; string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.
I would like to return multiple values from one function to access in different functions. For example:
int function1(//what goes here?) { int a ; a = 1 + 2 ; int b ; b = 3 + 4 ;
return (what goes here if i want to return the value of a and/or b to use in another function?) ;
void function2() { //now i want to use the value of a here to use in an equation, how do i do that? //now i want to use the value of b here to use in an equation, how do i do that? }
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 used to use map to access elements. map has a good feature that it sort the element automatically. Now I need a map which can access element through multiple key values. So I choosed boost::multi_index_container. I defined a container as follows.
struct elem { int a,b; elem(int aa,int bb):a(aa),b(bb) {} };
typedef multi_index_container <
[Code] ....
What I am wondering is whether boost::multi_index_container can sort elements automatically. Specifically, are all elements extracted through iterator from begin to end shown below having b values between 2 and 100?
test t; test::iterator begin = t.lower_bound(make_tuple(1,2)); test::iterator end = t.upper_bound(make_tuple(1,100));
I basically need to take line1, line2, and line3 and return them to the reverseString function. Also, I am not allowed to do anything like make my own classes. I have to stick to the basics and no higher level programming techniques since we have not learned them yet.
get my code to display a table with values from a file. my current code fills up all the sections of the table with the same data. here is what I need: from a file .txt I upload numbers that should show a table like this :
Lake Beach Average E-Coli Level Recommendation Ontario Kew Beach 47.12 OPEN Huron Goderich 51.13 CLOSED Simcoe Sibbald Point 0 INSUFFICIENT
my problem is in the last two columns. The ave. E-coli has one value for all which should look like the above table but my code doesn't. Also my recommendation shows the beach # instead of open close or insufficient.the data is:
Each Element named Bookmark has 4 attributes, Name, Folder, Time, and Chapter.
I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?
So the premise of my code is to read in a 2d array from a .txt. The array is a game board but the first two lines are what determine the size of the board. After i read it in i want it to find wherever te character "U" is, and then display the array but only showing U and whats around it. Problem is i cant get the array to print the right size and the code for displaying the U is not working either.
ifstream inputFile; int boardSizeRow; int boardSizeCol; inputFile.open("C:UsersMichaelDesktopfileboard2.txt"); inputFile >> boardSizeRow; inputFile >> boardSizeCol; inputFile.get();

How difficult would it be to program a hash-map system where each "key" can have multiple values under indexes?
For example: "Word" -> 45(index 0) , 67(index 1) , 12(index 2). What could I start with to program this or where could I find a pre-made system that does this?
I am trying to use struct to store variables from a text file and use them in the main program. I have first tried running the program without using struct and declaring the variables within the main program and it runs fine. But after using struct, it gives no compilation error and a segmentation fault as output. Also, if the size of file/variable size is unknown can I declare variables as char string[]??
The code is as below:
Code:
#include<stdio.h> struct test { char string1[10000];
I am trying to read user input for recipe ingredients which must include a ingredient name, and may include a quantity and a unit. Example: Stone ground flour 2 cups or Sugar 1 Tbsp or Milk. The problem I am having is that the string gets cut off after a space when multiple words are used for the ingredient name.
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've got some code in C++ that does some basic analysis on price data and I run it from the cmd prompt. One of the functions I had built to read in the data is as follows:
How would one merge this type of code into a Qt GUI? Ideally, I'd like to use something like QFileDialog to open up a folder with my data files, select a file, and then read the file that the user selects. Would the main.cpp look something like this?
int main (int argc, char *argv []) { QApplication prog (argc, argv); QPushButton *load_button = new QPushbutton ("Load File"); QObject:: connect (load_button, SIGNAL (clicked()), &prog, SLOT ( (ReadPricesfromFile function?); load_button-> show (); return prog.exec ();}
I am trying to read data from more than one file at once. The files are different types e.g. one is a text file one is an xml file like so, StudentInformation.txt, CollegeInformation.xml. The files are all stored in one place, in this case on the D drive of a local computer. I am trying to locate any files in the D drive with a file extension of .txt or of .xml (there may be more than two of these files in the future, so I'm trying to allow for that). Then I want to open all of these files, extract the information and output all the information in one display window. I want all the information from these two or more files to be displayed together in the display window.
Here is the code so far. It is throwing up errors.
I tried to make the program read from a file text the first name or last name but o cant seem to get it. i tried alot of different ways. how can i get the array of structure code to read form a file?
#include <iostream> #include <fstream> #include <string> #include <cstdlib> using namespace std; const int NUM_STUDENTS = 17; const int NUM_QUIZZES = 10; const int NUM_EXAMS = 5;
