C/C++ :: Warning / Assignment From Incompatible Pointer Type
Apr 17, 2014I'm working on a program and everything works except for the follow function:
void swapHex(int x, int byte1, int byte2) {
unsigned char *b1, *b2, tmpc;
printf("%d in hex is %x
", x, x);
printf("swapping byte %d with byte %d

I get the following errors when compiling:

C :: Function To Read A Text File - Incompatible Pointer Type
Nov 3, 2014So for a project, my professor sent out two pages of code containing functions to read a text file (since we do not know how to write this on our own yet). I've got the code working on Orwell IDE and it gives me 2 warnings saying
"Passing argument 1 of 'readFromFile' from incompatible pointer type"
"Passing argument 2 of 'option2Print' makes integer from pointer without a cast"
The Orwell IDE seems to just bypass these warnings and compiles the code correctly. However, when I transferred my files over to my desktop using BloodShed (what the professor uses), instead of getting a warning I get an error and the code won't compile.
I assume it will not compile on his computer either since he uses the BloodShed IDE.
I don't know how to put the code directly into the text neatly, so a attached a .zip file with my code. The "storms.txt" file is also included. (the file that will be read).
C++ :: Passing A Function Pointer As Template Argument To A Class
Aug 15, 2012I have in the past written code for templated functions where one function argument can be either a function pointer or a Functor. Works pretty straightforward.
Now I am in a situation where I am actually trying to pass a function pointer as template argument to a class. Unfortunately this does not work, I can pass the Functor class but not the function pointer. Below code illustrates the issue:
Code:
#include <string>
#include <iostream>
#include <sstream>
#include <cstdlib>
// For demonstration
const char * external_library_call() {
return "FFFF";
[Code] .....
The idea is to have the definition of the Record class simple and readable and have a maintainable way to add auto-conversion functions to the class. So the lines I commented out are the desirable way how I want my code to look. Unfortunately I could not come up with any way that was close to readable for solving this.
C :: Correct Way To Call A Function Within Main That Has File Pointer Parameters?

C :: File Opened In Main And Passing Pointer To A Function
Sep 14, 2013I am getting a few compile errors for what might be a simple thing to do. I am opening a file in main, passing that pointer to a function and checking the contents of that file with a regex before I pass it on to build a BST. I am getting the following compile errors, what is wrong. Here are the errors:
Code:

C :: Modifying Linked List - Passing Pointer As Argument
Feb 27, 2015I am having trouble modifying a linked list. I am writing a function to delete the last node from the linked list, but it gave me incompatible types error.Here is my struct:
Code:
typedef struct PCB{
int id;
struct PCB *next;
struct PCB *prev;
}PCB_rec, *PCB_p;
Here is my function to delete the last node (given the pointer is pointing at the last node of the list):
Code:
void del_last_node(PCB_p *process_list){
PCB_p temp = process_list;
if (temp->prev != NULL){
temp = temp->prev;
[Code] ....
And here is how I called the function:
Code: del_last_node(&process_list);
It gives me the following errors:
initialization from incompatible pointer type at line:
PCB_p temp = process_list
assignment from incompatible pointer type at line:
process_list = temp

C++ :: Function Call Missing Argument
Mar 7, 2014We just started going into classes for my C++ class. Everything looks right but the error is saying i'm missing an argument in my getspending call.
Heres the code:
for (int i; i < 0; i++) {
cout << members[i].getfirst << " "<< members[i].getlast << endl;
cout << "member ID: " << members[i].getmem << endl;
cout << "They have purchased " << members[i].getbooks << " books" << endl;
cout << "$" << members[i].getspending << endl;
}
Here's my get spending function:
double memberType::getspending() {
return spent;
}
What argument am I missing?
Visual C++ :: Error C3867 Function Call Missing Argument List For Calling Thread Function

My code excerpt is:

One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.

C++ :: RPG Game - Function Call Does Not Accept Argument
Apr 20, 2013I was trying to look up solution for this for quite a while already but found nothing. I am writing a simple console based turn based RPG game for my class project. I was trying to have a member function attack() in class of the player character, which affects the component called health of the class Enemy. both this classes are inherited from the base class Unit. I tried to pass the object of type enemy as an argument to the function attack, but the function call gives me Error: too many arguments in function call. Here's the code for classes:
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>

C/C++ :: Change Function Argument To Negative During Call?
Feb 28, 2015We are programming a function calculator and my instructor hinted that the add() function is almost exactly like the subtract() function and we would only have to write one function if we "called it in a special way." This got me thinking, can I turn a function's argument to negative during the call to make it subtract?
Example:
void addSub(int &num1, int &num2)
into this
void addSub(int &num1, int -(&num2))
Would this work when passing by reference?
C++ :: Passing Argument Into Function
May 21, 2013How to pass an int that I got from user input into a function to use it. I am trying to print out the words to a string of numbers.
I got the input from user.
I got an absolute value of the input.
I then separate the string into individual digits and name them.
I can print these out.
Then I started my if statement by checking if the original input was zero, and if it is, printing zero and exiting.
Then I an trying to pass the digits into a switch function and this is where I go off the rails.
Code:
#include <iostream>
#include <string>
#include <cstdio>

C/C++ :: Passing Function As Argument
Mar 11, 2015I have two questions :
1)

Why ptr_func1() does not work here?
IntelliSense: expression preceding parentheses of apparent call must have (pointer-to-) function type
2) How can i pass func1 to func2 as parameter?
I tried void func1(void* function), but I think I'm wrong here.

C++ :: Allocate Memory In A Function And Call From Main
Aug 30, 2013So my assignment is to create a program that calls for a function in main that dynamically allocates an array[3] and then have pointers with multiple levels of indirection and pass them by reference so they are not lost after the function. Here is my code:
#include <iostream>
#include <array>
#include <iomanip>
#include <string>
[Code]....
Next part is to ask user for two non-negative numbers and then get the length of those numbers and create an array. for the size of each number they input. Then to separate those numbers and add the cross-sums.
