C :: Calculate Cost For Production Of Open Top Cylinders - User Defined Functions
Feb 20, 2013
I have this program I wrote to calculate cost for the production of open top cylinders and how to translate it into user defined functions. Here are the user defined functions I need to use instruct() get_area() comp_area() and print_area_cost() so the program will be in 4 parts.
Code:
#include <stdio.h>
int main()
{double radius,height,cost,single,all;
float surface_area;
int count;
double pi=3.14159265;
printf("Enter the radius of the base in cm^2:

So I received an error of "type name is not allowed" and I don't know how to fix this.... Here is the code:
retrieveData(string Name, double wage, double hours, int exemptions, char Status);
dataCalculations(double wage, double hours, int exemptions, char Status, double grossPay, double ficaTax, double incomeTax, double netPay, double taxWithheld);
sendData(string Name, int ID, double hours, double wage, double ficaTax, double incomeTax, double grossPay, double netPay);

How can we build unit-tests for functions of libraries, those with user-defined types used as their arguments ?
For example
CRecord func(Myclass * class, BSTR * name, CComptr<xxx> & something);

So im trying to create a program that will calculate a shipping cost. I'm stuck on trying to calculate the actual milage and cost. Example being 1400 miles for a 2lb package would be $2 for every 500miles. so it would cost $6. But Im having trouble getting the program to round up the 1400 to 1500 so it charges the correct amount.
I know there would have to be a way to do this without programming all the conditions.
Also the course has not reached loops yet.
Code:
// This program will calculate the shipping charges.// The shipping rates are based on per 500 miles shipped.
// They are not pro-rated, i.e., 600 miles is the same rate as 900 miles or 1000 miles.

#include <stdlib.h>

I am currently working on an assignment.
#include <iostream>
using namespace std;
int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);
[Code] ....
I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.

The point of this is to calculate the total of the monthly costs of these 6 expenses and then to show the annual cost. However, there's just a couple of things that's giving me problems and it's the calcMonCost in my code. The error says that it is more than one instance of overload function and also that an unresolved external symbol. Everything else is fine. What does this mean?
Code:
#include <iostream>
#include <iomanip>
using namespace std;
void calcMonCost (double, double, double, double, double, double &);
void calcAnnCost (double, double, double, double, double, double &);
void getData(double &lnPymnt, double &insure, double &gas, double &oil, double &tires, double &maint);

The instructions call for the user to define the size of the array and all I have ever done is use a predefined size for the array and then let the user fill it. Here is what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void Display (void);
void random (int *, int);
void Ascending (int *, int);
void Descending (int *, int);

#include<iostream>
using namespace std;
#include<set>
class person{
int age;
[Code] ....
When I executed the above code it displays
Age is 37
Age is 25
Here I have defined operator< so that set can identify the order of person objects. I am clueless how set could identify that
person p[3]={person(25),person(37),person(25)};
I have provided one duplicated object with age 25
I havent overloaded == operator also,then how it could identify?

I am writing some code to bubble sort a list of randoms numbers, 10 at the moment. I want to be able to user input the amount of elements that would be sorted. I think i'd have to use vector instead of arrays, but unsure how to do this. Or, how to be able to change the size of the array.

Write a program to ask a user to input a symbol from the keyboard and to output that symbol in a n X n/2 sized V where n = the width of the V. You must use a loop to process the data
I am stuck at trying to figure out how to do the actual output formatting. This is where I am sitting currently.
string character = "";
int vheight = 0;
Console.WriteLine("Enter the character you wish to use for your V: ");
[Code]....
so Im really just a bit stumped on how to get the actual V shape to be formatted..

STRING s1 = “FOOBAR”
Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?

Write a program using user-defined function which is passed a string and that function should cycle the string.(Do not use any string related functions). E.g.
If the string is : Chetna then it should print as Chetna, hetnaC, etnaCh, tnaChe,naChet, aChetn
Ans.
#include <iostream>
using namespace std;
char swamp(char a[], int x) {
for(int k=0; k<=x; k++) {
char l= a[x]; a[x]= a[0]; char p=a[x-1]; a[x-1]=l;
for(int i=1; i<x-2; i++) {

Suggest a function that sorts the inputs vertically according to the order given by the user? I made this one
void order(string order, char index[][15]){
int counter=0,line=0,i=0,j=0;
for(i=0;i<=15-1;i++)
{for(j=0;j<=15-1;j++) {
if(index[j][i]==order[counter])

We had to write a "selling program for computers, laptops and tablets", which I did but for the extra credit, we have to have those three points in the application and I have tried but how to do the "extra credit" part, which I really need.
1.) A loop to prompt the user if they would like to place another order
2.) At least one user-defined function
3.) An enumerated data type, array or struct (structure)
I did one of these three, it's a "DO WHILE" loop asking users if they want to make another order, it's right at the beginning of the code.
Code:
#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>
using namespace std;
double desktop();//function prototype
double laptop();
double tablet();

im tasked with creating a linear search script using functions on a 10 element array. the elements are to be supplied by the user as is the search target.
I understand how to create the array and gather that information from the user as well as howto set a variable for "target", this is what im calling it. Those two parts are simple enough.
I am not fully understanding the calling of an array in a function as a pointer. i semi understand the use of a pointer and howto call a normal pointer in a function. i also understand that an array is nothing more then a "special" pointer with a set of consecutive address blocks for the size of the array.
My first user defined function is simple enough
Code:
ReadArray(int A[], int size){
int i;
printf("Please enter %d integer numbers separated by spaces:
", size);
for (i = 0; i < size; i++)
scanf("%d", &A[i]);
}
Sso nothing out of the ordinary there. that should be a standard for loop and use of scanf, sadly prof has not covered ssanf or any of the other options so i am stuck using scanf for now. maybe someday down the line in a other program or after this course ill get the chance to learn about better options for gathering data from the user.
I am confused as to my next function:
Code:
void SearchArray(int A[], int target, int size);
I've not written any code here yet as im not sure if i should call the A[], or *A for the first type of the function?
If i call *A do i then use something like this for my search:
Code:
for (*A = 0; *A < size; *A++)
if (*A < target) or use A[] insteadA?
Code:
for (i = 0; i < size; i++)
if (A[i] = target)
