C :: Create Program That Takes In Information And Formats It Into 3 Columns - Float Variable Not Working
Dec 12, 2013
Here your supposed to create a program that takes in information and formats it into three columns.
I can't seem to use the float variable unitprice with decimal places here for, if I try to use %.1f and type in an input, the program seems to skip over the second scanf function, not allowing me to put input into the third scanf function as the program runs before I can.
I can use %f on its own and it works but this creates too many zeroes(and you're supposed to set the currency limit to $99999.99).
Code:
#include <stdio.h>
int main(void) {
int itemno, month, year, day;
float unitprice;
[Code]....
So the output should look like three columns. It's just the float that is the issue here....
I'm just getting back into the swing of things after a long time of not programming. I'm trying to create a program which takes in command line arguments and prints the last one. My code is as follows:
#include <iostream> #include <vector> #include <string> using namespace std; int main() { string x; vector<string> arguments;
[Code]...
And the error message I receive, a simple but frustrating one, is as follows:
Enter arguments, enter STOP to stop: Segmentation fault...
I have a school project in which need to create a function that takes a File Object as a Reference Parameter. Supposedly, it should allow me to read the first piece of data from others separated by a space from a file. The later be able to continue reading from the next piece of data.
I know how to set things up to read from the data file, such as using
I am using Dev C++ compiler on Windows 7 and was programming a piece of code that is supposed to do the following -
Create a structure to store information about products for sale in a store. It should store information about the product name, the price, and the product number and then create an array of products called Inventory. Add five products to your inventory.
But for some reason, which is unknown to me, I always seem to get a compiler error. And this is what i have so far -
I need to be able to make matches from the data i input, and also classifying between male and female. matches for person with specific traits (not one in the program) i really tried for the first part and now the rest is mentally disturbing me. and also to generate a report of partners found.
#include<string.h> #include <iostream> using namespace std; char username[20]; char storedusername[20]; char password[20]; char storedpassword[20]; int loginresult; char name[20];
I am writing a program that models the ups & downs of a particular stock. Everything is pretty much done, except that I need to create another event to notify that saves the following information to a file when the stock's threshold is reached: date & time, stock name, initial value & current value. I have something like this so far:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO;
[Code]...
I feel like i need something along the lines of
s.stockEvent += new Delegate( ???? ) in my myFile class so it know when the threshold is reached, to write the information of the current stock to the file.
I need to create a main function with a one dimension dynamic array with float data type. The total number of array elements must be controlled by a user input from the keyboard. Test data is three different lengths 3,6,9 of the array. The lengths have to be set up at run time from users input. I understand how to create dynamic array but not where the user inputs the length of the array. How would I implement this?
I have to make a program that takes several numbers into an array into a function, and send them back into the main function multiplied by 1.13. This is what I have so far:
#include <iostream> using namespace std; void connell(int&n[20]) main() { int num[20];
[Code] ...
I do not know how to get numbers from an array from a main program to a function.
Write a C/C++ program that reads a boolean expression in sum-of-products form and generates the sum-of-minterms form (canonical form). Use single letter to represent variables. The following symbols will be used to represent operators: NOT: ~, AND: *, OR: +. Other operators won't be used.
Examples of execution: number of variables: 2 SOP expression: ~A+B output: ~A*~B + ~A*B + A*B
you have been tasked to write a program that takes two complex number and return their sum.However the + operator will not worl with complex numbers and you figure you need to verload the + and the assignment opeartor=.Ypu have come across the program [URL]
implement it and the client code to see it rune for the following complex numbers:
c1=3.0-4i,c2=8+4i
i have 3 files,driver.cpp,Complexnumber.cpp and complexNumber.h
complex.cpp is as follows
#include <iostream> using namespace std; class ComplexNumber { private: double real; double image;
Just using Find in my source code to look for variables or whatever, works once or twice then just stops - Doesn't find anything even if it's there. If I restart VS it works again, but not for long.
Im using apmatrix and im inputting values into a 4 by 4 matrix and im getting all these errors that have nothing to do with my cpp file so im guessing its apmatrixies fault. Also I put in the cpp and header file of both apmatrix and apvector into my project folder. Heres my code:
error C1189: #error : The C++ Standard Library forbids macroizing keywords. Enable warning C4005 to find the forbidden macro.c:program filesmicrosoft visual studio 11.0vcincludexkeycheck.h2421TheMatrix

I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.
I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time { short year; short month; short day; short hour; short min; };
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.
A program which takes input from user and write it to a file then it reads data from that file then it should search for specific data such as email adresses or url etc.
I have a N queens (actually 8 queens to be specific) program that accepts the numbers in order by row. I need to get it so it accepts the numbers in order by column. At first glance I thought it was just one space different, but it turned out not to be and how to get the one space difference in there. My current code (which I'm aware isn't doing the column accepting right) is:
Code:
#include <iostream> using namespace std; int main() { int board[8]; cout << "Enter the columns containing queens, in order by column: "; for(int i = 0; i < 8; ++i) { cin >> board[i];
[Code]...
What the output should be:
Code:
Enter the rows containing queens, in order by column:
The program need to find mean of elements in columns which are divided by 3. And to print which colmn has the greater mean
Example
For matrix: 7 9 5 17 15 30 29 34 60
Program print: 0 12 45. The greater mean: 3 column.
I wrote this code and it prints 0 12 45 idk how to find which column has greater mean?
Code:
#include <stdio.h> #define max 50 int main() {int n,m,i,j,k,d,br=0,suma; int a[max][max]; int b[max][max]; printf("Kolku redici i kolku koloni da imat matricite: "); scanf("%d %d ", &n,&m);
I'm not sure why Im getting a wrong Sum. of the Columns.
Write a method that returns the sum of all the elements in a specific column in a matrix using the following header:
double sumColumn(const double m[] [SIZE], int rowSize, int columnIndex)
Write a test program that reads a 3-by-4 matrix and displays the sum of each column. here is a sample run:
Enter a 3-by-4 matrix row by row: 1.5 2 3 4 5.5 6 7 8 9.5 1 3 1 Sum of the elements at column 0 is 16.5 Sum of the elements at column 1 is 9.0 Sum of the elements at column 2 is 13.0 Sum of the elements at column 3 is 13.0
#include <iostream> using namespace std; const int SIZE = 4; int rowSize=3;
Write a C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.
This is a sample output. Notice how the program prints a counter (1, 2, 3, ) for user keep track of how many numbers were entered so far. Include this feature in your program.
I have tried different ways to get the result from while loops, do while, and if-else statements. We have not done any max/min problem in class and the book was kind of vague. We have not learned arrays yet in class and I can't figure a way to compare the integers the user inputs as it is an infinite(from what I am reading) amount aloud. The problem I am seeing is the loop works and stops with the sentinel value but the INT_MIN is using the sentinel value. I also have not addressed the input of negative numbers yet with the first program I wrote, maybe one of my problems.
Code: /*File:HW2Q3.c, A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/ /*header files*/ #include<stdio.h> #include<limits.h> /*****start program*****/ int main() {
[Code] ....
I have also tried this way as well, min value still comes back as -1 the sentinel value, and the else statement is being ignored. I am sure it is something silly but I am lost and confused at this point.
Code: /*File:HW2Q3.c, A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/ /*header files*/ #include<stdio.h> #include<limits.h>
