This is my code so far and in my else if statements its sayin "Expected Primary Expression Before "Else"
What do i do?
#include <iostream>
using namespace std;
int main () {
//declare variable
double n,a,b,c,d,total;
[Code] ....
I keep getting an error here and cant quite figure out why,
Code:
else if (mainMenu == 3){
cout << "Please make a selection" << endl
<< " 1) Withdraw from account" << endl
<< " 3) Back to main menu" << endl;
cin >> withdrawMenu;
if (withdrawMenu == 1){
[Code] ....
This is what i have example code in c++:
#include <iostream>
class Foo{
public:
void bar(){
std::cout << "Hello" << std::endl;
[Code] ....
After compiling it is giving error as :
foo.cpp: In function ‘int Foo_max(Foo*)’:
foo.cpp:26:37: error: expected primary-expression before ‘int’
foo.cpp:26:46: error: expected primary-expression before ‘int’
work out this error?

My group's chocolate vending machine code is clean, but has a problem.
#include <iostream>
#include <iomanip>
#include <cstdio>
#include <cmath>
using namespace std;
int main() {
// Variables from function "chocoSelect".
[Code] ....
The functions doesn't seem to link in proper. Also, for the "chocoSelect" function, if a user enters a selection number other than 1 to 5, the machine will stall and wait for 10 seconds to try again. How?
I wrote a program, that generates 20 random integers, and stores them in an array. Then I decided, to build more functions to it, i.e why not have it to display the lowest integer of an array. I created my function,
Code:
int minValue( int field[ ] )
and got my code in side, which (technically) works. In my main() function I'm calling
Code:
printf( "The smallest value of an array is: %d
", minValue( field[] ) );
and I'm getting an error trying to compile it.
Code:
randomArray.c:62:74: error: expected expression before ']' token
printf( "The smallest value of an array is: %d
", minValue( field[] ) );
I'm pretty new to C, and keep getting an error. Basically I'm trying to convert a ppm image to all red. Here is my code that I can't get to work:
Code:
change(pixel_t *PIXEL, &w, &h,pixel_t *buffer);
And here is the beginning of my convert function:
Code:
void change(pixel_t *pixel, int w, int h, pixel_t *buffer) {
int average, sum;
int i;
pixel_t *pointer;
Everything else works fine. I keep getting an error when I call the convert function. It says "expected expression before pixel_t" and "too few arguments to function "change". I know that everything else in the main is working.
It's been awhile since I've coded in C. I'm picking it back up to get some practice. I'm going through my old programs from a few years ago, and I ran into one where I'm calculating the entropy of a file. The problem I'm having is that everytime the program runs, no matter what file I choose for it to calculate the entropy on, it gives 3.00000 as a result. I've gone through it and can't seem to figure out why it's possible doing that.
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <string.h>
#define SIZE 256
int entropy_calc(long byte_count[], int length) {
float entropy;
float count;

I have a COM exe which runs fine on all machines that I have used except one. On a particular machine, the COM exe does not start even after trying to execute it manually (do a double click on the file from explorer).
There are no error messages as well. what could be happening ?
My need is that i need to design a program for a machine. The machine takes "x"qty of load, refines 30% of it and sends back the 70% to the initial position. after how many times, does the qty of the load refined will be equal to the initial load and how many times does it need tot be refined?
View 1 Replies View RelatedHave a program which given a C source code file, gives back RAW MACHINE CODE, which means it doesn't have to be a executable on his own.
Like:
Given a example function for C:
int stdcall Function(void)
{
return 0;
}
Gives back the Machine Code for the Example Function.
It doesn't need to be actual C code, it can also be like:
type int
return 0
Or also it can be a straight assembly-to-machine-code compiler.
Is there any Library? Or even a external tool I can look into?
I am making a finite state machine for a lab. I have here a 2 files with the code for the FSM. I know it isn't finished yet, I know what needs to be put in. The only things I would need help on are the errors that I get.

#ifndef _WARRIOR_
#define _WARRIOR_
#include "State.h"

Write a program that simulates an adding machine. When a zero is entered it should print the subtotal of all the numbers entered from the last zero that was entered and reset the subtotal. When two consecutive zeroes are entered it should print the total (not the subtotal) of all the numbers entered and terminate the program. Example:
1
2
3
0
subtotal 6
4
5
-2
0
subtotal 7
8
0
subtotal 8
0
total 21
Be careful this program needs a bit more thought than you might think at first. To get full credit you must make sure it also works for the 0 - 0 case. Example:
0
subtotal 0
0
total 0
The problem is, after I enter the integers and type 0, it shows the subtotal which is what I want; however, when I type more integers and type another 0 to see the subtotal again, it shows the total instead. The subtotal should reset whenever a single 0 is typed and the total should only show when two 0's are inputted simultaneously. Also, after the user enters two 0's simultaneously and views their total, I want the program to exit by saying "press any key to exit." Is there a special name for that to happen? Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main() {
int subtotal = 0, total = 0, number = 0;
bool input_zero = false;

I have part of it done but im not sure how to get my amount balance to get into my other functions from my file...
#include<iostream>
#include<fstream>
using namespace std;
void welcomeUser();
bool readFile();
void menu();
[Code] ....
and the amount saved that I have in the file is 1200
Is there a way I can extract Machine / Hardware ID and OS Version using VC++?

Everything my be referenced by pointers. When I build I am being told segmentation fault: 11. From what I have gathered that means there is a problem with my memory allocation correct? I'm including the custom header file and the main.c as well.

I've recently started creating a bingo caller application. I need in changing numbers to different text boxes. When a number is called it will be displayed in a text box and the last four numbers previous to that. However the oldest number needs to delete and for the remening numbers to move when a new number is called.

I have a global var (m) with an initial value 5.
I have a template class (A) that derives from a either a base class that has a member (_A1.m) or not (_A0), based upon it's template parameter. class (A) has a member function (fn) returns the value of (m) as it understands what (m) is.
However, this gives different results compared with a non-template class in a similar scenario. I'm expecting that if derived from _A1, that m should be taken from the base class scope and if derived from _A0, it should be taken from the global one.
Here is the code for your amusement:
int m = 5;
class _A0 {
public:
_A0(int) {
[Code] ....
This compiled using g++ 4.5.3 and 4.6.3 with the same results:
Global value of m is: 5
B0 class has no internal m member. Object resolves m internally with value 5
B1 class has internal m member. Object resolves m internally with value 3
A<_A0> class has no internal m member. Object resolves m internally with value 5
A<_A1> class has internal m member. Object resolves m internally with value 5
In this code:
#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Before the program ends, at return 0;
I would expect the CBox destructor to be called 3 times but it is being called 6 times? Why? Also in this code:
#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Why is the destructor called 3 times? When have you really destroyed a CBox? Doesnt emplace only create it and store it, then thats it?

I just wrote the following simple program:
Code:
#include <stdio.h>

The output increases x by 0.1 as expected until x=1.5. After that x becomes 1.600001 and not 1.6 as expected.
I'm trying to perform a simple input operation, and check to make sure that whatever the user input is a valid input (is within data type bounds, is correct data type...). But when I get to ignoring the input, I keep getting an error.
