Code:
/* Demonstrates using the gets() return value. */
#include <stdio.h>
/* Declare a character array to hold input, and a pointer. */
char input[257], *ptr;
[Code]....
I just got this from the book that I am using and it is for testing for input of a blank line and readers are being warned in using this format (line 18):
Code: while ( (*ptr = gets(input)) != NULL)
What is the correct syntax if a gcc compiler is to be used?

I'm trying to compile a library for use with PoLabs Pokeys 56U USB device (PoKeys56U) on Linux Mint 17 64-bit.
I'm using the information from here - New cross-platform library for all PoKeys devices - MyPokeys
When I run
sudo make -f Makefile.noqmake install
I get the following errors;In file included from PoKeysLibCore.c:22:0:

When I try to compile a program from a C book I am following I am getting these errors, I have looked for ways to resolve it but I wasn't able to.

Every time I try to compile this, I get the error message, "error: no matching function for call to" on lines 18, 45, and 46. Basically every time I try to call on the function sales and printStock. I don't know what the message means or why I get it.
#include <iostream> #include <fstream> #define N 10 using namespace std;
I'm trying to make a simple C++ program in which the user must try to guess a number, if they guess too high it says "too high" and if they guess too low it says "too low".
I also decided to add a feature which allows them to select how many tries they would like to guess the number. I tried to make "tries" type an enum so if the user could not pick an invalid number but for some reason i cannot use it in an if statement.
here is the code and i am getting the first error on line 27:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int guess;
I have a question related to switch statement, which the switch in class employee2 gives me error at output. Program compiled well. I am using Code::Block Compiler V10.5. I have created object of class employee2 in main() function to get data from user, store it and display it. At the output, Compiler doesn't show actual output what i am expecting. The fun thing is my compiler printed emocion like (), where (hourly/monthly/weekly) was supposed to print.
Code: #include <iostream> using namespace std; enum period {hourly,weekly,monthly}; class employee2 { private : char ch; period x; double compensation;
I have written a program that stores employees in a database object. You can Add, hire, fire, promote, demote, and display employees. The program uses an interface, a database class, and an employee class with member functions.
The strange behavior is in my switch statement in interface.cpp. I have a '#' that represents a command line. Add and Display functions are ok, but if I hire, fire, promote or demote. It will display '##' for the next input. I ran the debugger and after hire/fire/promote/demote is called, the first if-statement goes to 'else' and I'm trying to figure out why.
if (comboBox1.Enabled == true && textBox5.Text != "") { OleDbConnection con = new OleDbConnection(); con.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" + @"Data Source= c:usersmert" + @"documentsvisual studio 2010ProjectsPayrollCSWindowsFormsApplication7P ayrollDB.accdb";

this is my code. I am getting this error on "cmdole2" query.

Look at case 2, which the user supposed to key in a new input, the problem is the value will never got into main function, I don't know what should I modify with the function.
I can't seem to figure out whats causing this error: statement cannot resolve address of overloaded function . Error is before line 14 in bubblesortrand function. Thnx in advance.
void bubblesort(int num[], int a_size) { int i, j, temp; for(i = (a_size - 1); i >= 0; i--)
I am creating a pizza program for ordering a pizza and I have removed all the errors except for two. I have tried everything I can think of to fix this problem so it will compile, but to no avail. The only errors left are:
1>------ Rebuild All started: Project: Pizza Order App Midterm, Configuration: Debug Win32 ------ 1> stdafx.cpp 1> Pizza Order Midterm.cpp 1> Pizza Order App Midterm.cpp 1>c:usersindia-n-jerrydocumentsvisual studio 2010projectspizza order app midtermpizza order app midtermpizza order app midterm.cpp(57): warning C4390: ';' : empty controlled statement found; is this the intent?

The entire code is listed below seperated into 1 header and 2 cpp files.
// OrderPizzaApp.cpp : Defines the entry point for the console application.//
I have an if statement that should either match a text variable that the user has entered and a another text variable that has been got from an array but they won't match even if they are the same,Im at a lost with it.
I'm taking an intro to c++ class and during an exercise I ran into multiple errors that are out of my knowledge to fix. The rest of the class is using Visual and that is all the instructor knows so i'm in my own figuring out Xcode. Basically I wrote the same program twice but one has a different struct and I get all sorts of errors with it. understand what the errors are and why they occurred.
The working program is this:
#include <iostream> #include <fstream> #include <iomanip> #include <cmath> using namespace std; struct point { public: double x1,y1; double x2,y2;
[code]....
This program does not compile and I get the following errors:
stl_iterator_base_types.h
1) Symantic Issue No type named 'value_type' in 'myPoint' 2) Symantic Issue No type named 'iterator_category in 'myPoint' 3) Symantic Issue No type named 'difference_type' in 'myPoint' 4) Symantic Issue No type named 'pointer' in 'myPoint' 5) Symantic Issue No type named 'reference' in 'myPoint'
I'm compiling some open source code (originally written for Linux / gcc) which uses the following line to determine if a particular section is being compiled for an x86 processor:-
have several linux header files included and when I compile my program I get the below errors..Am I NOT supposed to use some of these headers? Source is below as well.Looking through the headers mentioned in these errors, it's looking like stuff really is defined in multiple places...

I want to use two separate files in 1 program, but cannot get it to work. I don't know if it's my files or the compiling thats wrong. I have never used 2 files in my programs so far. Only used #include <stdio.h>.
Here are my files: extern_static.c Code: extern int i; int main(void) {
I have a FTP server, client program and thus I can easily transfer files, however what I want is to modify the program such that server receives a c/c++ file, compiles the output, and sends a text file back to the client containing the output. The program should also take note that errors are also transferred.
