C++ :: How To Read Input Of Arbitrary Amount Of Numbers Instead Of Specific Amount
Feb 25, 2015
I'm trying to make a program that allows the user to input an arbitrary amount of numbers and finding the largest of all the inputs but I keep having problems with the output.
javascript:tx('
#include <iostream>
using namespace std;
//******************************************
//CLASS COMPARATOR
//******************************************
class comparator {
public:
comparator();
[Code] .....
And regardless of what numbers I enter, I always get the output of 10. Also I got the EOF idea from my textbook so if there is a better way of doing this I'd like to hear it. I don't know any clear ways that looks nice to end the while loop when the user doesn't have any more numbers to enter.
I wrote a code to read a specific amount of data from file until terminating set is reached. however the code does what its supposed to correctly until it reaches the 5th loop it justs stops responding. I've checked the reading file and all elements are correct in the file.
Code: int main(void){ FILE *file1; FILE *file2; FILE *file3;
A Bookseller makes special discount for multiple orders of a book as follows:
AMOUNT and DISCOUNT as follows.
5-9 5% 10-14 10% 15-19 15% 20+ 20%
Write a C main function to read the amount of order from the standard input and compute and print the total price of the given order after the discount. Assume that unit price of a book is 10.00$
My problem is that.When i start with this
Code: #include<stdio.h> #include <stdlib.h> int main(void) { int number; float TotalPrice; printf("enter a number:");

I get 0 if i enter a number between 0 and 4(0 and 4 included). I don't know where I am doing a mistake. I also want to know if i can handle this buy just if statements. or how can i do it by while and for loops ?
Ok, so I am writing this program with 10 different functions, and one of those functions needs to count how many times 0 appears in a text file. I've done this before, but I am so stumped right now. Should I get the numbers from the 2d array I have, or should I just use the text file here? Here is what I have right now:
int toursMissed(int scores[][COLS]){ int counter; for(counter=0;counter<=96;counter++){ if(scores==0){ counter++; return counter; } }
Im trying to read and store several students information so that i can have an options menu where i can enter a student number and the program prints all the information stored about that student. The way i have it set up now, doesn't work for this because all info is reinitialized to stud1. Is there another way to store this info other than defining stud1, stud2,.....,stud200?
I'm currently working on a program to take the user's input as DDDD.CC and then converting it to the least amount of coins using quarters, dimes, nickels, and pennies. I was told to not use any doubles or floats as they would produce errors. And supposed to the use the library function atoi() after I take the input user's amount as a string to convert it into an integer.
So far the string input has worked and it produced the right number of quarters but it leaves off the cents. For example, I put in 352.23 and it gives the right amount of quarters but leaves off the 23 cents.here's my code:
#include <iostream> // Allows the program to perform input and output #include <stdlib.h> // Atoi #include <string> using namespace std ; // Enables a program to use all the names in any Standard C++ header int main() // Start of program execution { string line ;
Write a program that will input the amount of chairs sold for each style. It will print the total dollar sales of each style as well as the total sales of all chairs in fixed point notation with two decimal places.
The program runs fine I am just have problems with the output. I have tried a few different methods for the fixed point notation, but I am getting results like 324.5 rather than 324.50?
#include <iostream> using namespace std; int main() { //Declares variables for chairs float americanColonial; float modern; float frenchClassical;
Create a program that will let the user input an amount in the form (367). The Program should determine the no. of coins for each dominations : 50,25,10,5,1. (using Turbo C)
I bet there's a simple function that can return the amount of RAM available on the computer, or perhaps the total RAM on the chip.
Basically I want a way of making sure my program never tries to allocate memory when it can't... I know that Windows should stop this happening anyway but I want to make sure the program can take care of certain things if it happens.
I'm trying to make a very simple reaction game where a random number flickers on the screen for a fraction of a second and the user has to then enter the number before another comes on the screen after a random amount of time. However I dont know how i would make it so that the user cannot enter anything after a certain amount of time has passed, below is my code?
Also FYI, clock_start is at 5100 because by the time the program actually gets to scanning in the first number the time is at an absolute minimum of 5050 milliseconds however obviously this is an impossible number to reach due to processing, my machine clocks in at 5080.
Code:
#include <stdio.h> #include <stdlib.h> #include <time.h> #include <windows.h> int main(void){
I’m writing an application for raw image processing but I cannot allocate the necessary block of memory, the following simple code gives me an allocation error.
double (*test)[4]; int block = 32747520; test = new double[block][4];
off course with smaller block size (i.e. int block = 327475;) it works fine. Is there an allocation limit? How it is possible to deal with big blocks of memory?
the program has to accept a keypress. It should wait for some fixed amount of time. If a key is pressed within this time, the program should call a function. If a key is not pressed in this time limit the program should continue its normal execution. The problem with getch() is that it essentially requires you to press a key and it does not allow other instructions to execute until the key is pressed.
Say I want to exhaust all the possible combinations of 10 variables to find all the solutions to an equation with 10 variables.
I could write out 10 'for' loops, but it would take a lot of space in the code and of course would take a lot of time. Another reason why I want to know this is because it could possible allow me to change the amount of for loops just by changing a number.
I.e., how can I contract the following code into a simple, short form?
for (a[0]=0;a[0]<=9;a[0]++) for (a[1]=0;a[1]<=9;a[1]++) for (a[2]=0;a[2]<=9;a[2]++) for (a[3]=0;a[3]<=9;a[3]++) for (a[4]=0;a[4]<=9;a[4]++) for (a[5]=0;a[5]<=9;a[5]++) for (a[6]=0;a[6]<=9;a[6]++) for (a[7]=0;a[7]<=9;a[7]++) for (a[8]=0;a[8]<=9;a[8]++) for (a[9]=0;a[9]<=9;a[9]++) if (...) cout << ... << endl;
send(s, content.c_str(), content.length(), 0); I'm executing the "dir" command to get a listing of Folders/files of one Folder. Then I read the Output of the file and send it over winsock to the Server.
Now, the Problem is, I don't know how I can handle the recv properly, cause I have to set the buffer size without knowing, how much data is actually transfered. Sometimes maybe no files are in c:filequeue, sometimes a 100k.
So I tried to make recv as a Loop:
Server:
Code: ...
while (rc != SOCKET_ERROR) { printf(" #"); gets(buf); //please no discussion about gets, I will Change this later ;) if (strcmp(buf, "ls") == 0){ send(connectedSocket, "LIST", 4, 0);
[Code] .....
now it works, but as the recv blocks, it will never leave the Loop, even when the Transfer is finished.What should I do?
I believe I could make unblocking sockets, but that's a bit complicated. Isn't there an easier solution, with malloc'ing the buffer or a Signal when to leave the recv Loop?
Write a program in C that will allow a user to enter an amount of money, then display the least number of coins and the value of each coin required to make up that amount. The twist to this program is the introduction of a new coin - the jonnie (value = $1.26). Therefore, the coins available for your calculations are: Twonies, Loonies, Jonnies, Quarters, Dimes, Nickels and Pennies. You can assume the amount of money user enters will be less than $100.00.
User enters $4.53. Your output should be:
The least number of coins required to make up $4.53 is 4. The coins needed are:
Say I want to leave a program running and it stops when I press F9 for instance, I'm looking for something like (and note this is just a generalization).
I need to create a program that continuously records data until the user enters '0'
The data that I read in is the student's last name, the year of the student (1-4), the major, the gpa, and the advisors name. I then need to print out how many students are in each year (1-4), the number of students each advisor has, the average gpa for each major, and so on. This is what I have, but I am stuck and think that I might be headed the wrong direction because the only thing working is the loop (not my gpa test calc).
//This program displays information pertaining to students #include <iostream> #include <string> using namespace std; int main () { int studYear; double average, studGpa; string studName, studMajor, studAdvisor, complete;
