C++ :: User Defined Functions - Type Name Is Not Allowed
Dec 5, 2014
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);

I am getting a compilation error from the code below. It is when i am naming a variable with my user defined type.

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:

#include<cstdio>
#include<list>
[Code]....
In the last line "graph.edge{x,y,w}" it says typename is not allowed? I have used nested class edge and pushing vertices and their weight in elist vector which is of type edge.

My assignment is : Please use C type strings ( array representation of strings). Write a program that will ask the user to enter a string. It will then regard that string as a worked-on string and allow the user to perform the following editing functions on it:
s – search
i – insert
a – append
d – delete
a – append
d – delete
r – replace
e – exit
s – search
This option will allow the user to search for a specified string in the worked-on string. If the string is
found, it will display the starting index (position) of the searched string in the worked-on string.
here is what i have so far.
#include <iostream>
#include <cstring>
using namespace std;
int main() {
char a_string[80];

I am trying to get a program to take two files and place them into a third file. I have searched all over this website looking for a solution and i can seem to find one.
My issue is that i keep getting an error 'incomplete type is not allowed' as well as 'no operator matches these ">>" these operands.'
#include<iostream>
#include<string>
#include <sstream>
using namespace std;

So, I ran into the above error. I can't post the actual code, but here is the setup... I have four classes: A, B, C, and D.
A.hpp
Code:
class A {
public:
virtual void foo( D& bar );
[Code] .....
In A.cpp I implement foo and use bar in a similar manner as shown in class C. The difference here is that in A.cpp I also include the header for the D class. I am a bit confused why I can pass bar to B::foo() and that works fine, but if I try to access bar in C::foo, I have issues. Currently I am just including D.hpp in C.cpp.

I have an enum like:
Code:
typedef enum mac_type_e{
STATIC_MAC,
BLACKLIST_MAC
} mac_type_t; and I want to use this type in a structure that's declared like:
Code:
typedef struct lan_mac_s {
UINT16 lanmacid;
enum mac_type_t lan_mac_type_pp;// user mac type per port, 20 mac_type_t array, 0 = static, 1 = blacklisted now,
The compiler tells me:
Code:
incomplete type is not allowed
enum mac_type_t lan_mac_type_pp;// user mac type per port, 20 mac_type_t array, 0 = static, 1 = blacklisted
But if I remove the preceeding "enum" keyword, it compiles fine.

When declare and assign an instance of a user-defined struct in a function. And the struct (theStruct) is not declared in the same header file as the function (theFunction). Like this:
files:
"A.h": declares the struct in a class (theClass)
"A.cpp": implements the struct
"B.h": declares the function
"B.cpp": implements the function, error here
I think making the instance (inst) a reference might solve this. But the instance is assigned to a return value from a function (returnFunc). Like:
void theFunction() {
...
theClass::theStruct inst = returnFunc(...);
//returnFunc() returns an instance of theStruct
//the error is at 'inst'
...
}
What do you think?

So I need to make a main function have no if/for/etc. statements so I need to move it to another function and call it in main. The problem is that it's a command line argument function so I'm confused on how it works. Here's an example:
Code:
#include <stdio.h>
int main(int argc, char* argv[])
{
printf("The program name %s", argv[0]);
if (argc == 2) {
printf("Argument supplied is %s", argv[1]); }
else if (argc > 2) {
printf("Too many arguments");}
else {
printf("One argument");}
}
How can i make this into two functions with main only declaring variables and calling other functions?

I have a basic vector/point class where I've overloaded a bunch of arithmetical operators:
Code:
#pragma once
class point {
public:
point() {
}
point(float p_x, float p_y, float p_z) : x(p_x), y(p_y), z(p_z)
[Code] ...
I can use it fine like
Code:
point p(50,50,50);
point q(50,50,50);
point t = p * q + q;
However when I put this point type into a struct and try to access the members after passing it through by const reference:
Code:
struct sextic {
point a,b,c,d,e,f,g;
};
inline static sextic sexticDifference(const sextic &p_sextic1, c
[Code] ....
This gives me an "operator not defined" error for compilation.

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.
#include <iostream>
using namespace std;
#define SIZE 10
float numbers[SIZE];

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++) {
