I think my linker needs an additional #include to be able to deal with int& anterior and int& posterior. I'm not sure as I'm new to C++. My version of Dev-C++ is Orwell V5.8.3.
I am having problems compiling this program. line 29 causes the error "left operand must be l-value".
// chap5proj.cpp : Defines the entry point for the console application. // # include <stdafx.h> # include <iostream> using namespace std; int main() { double mph, time, disPerHour, milesTrav;
I am getting this error when compiling my program with quincy:
Error: I value required as left operand of assignment
The program is meant to calculate how much parking costs based on the amount of hours in a park and what type of vehicle it is. the error is coming from my function definitions which i have just started to add in.
Code: float calcCarCost (char vehicletype, int time, float car) { if ((time > MINTIME) && (time <= 3)) calcCarCost =( CAR * time ); }
The error is on line 72 which is: calcCarCost =( Car * time);
I should probably point out CAR is already defined as a constant with a numerical value given and time is previously asked to be input in when the program runs.
The issue arises with case 3 where it tells produces an error when I attempt to compile and says "lvalue required for left operand of assignment error". How to fix this so that I can properly run the program.
"fatal error LNK1169: one or more multiply defined symbols found"
Here's my code:
#include "stdafx.h" #include <iostream> using namespace std; int main () { cout << "Avoiding Technology" << endl; bool status = true; int location; int a,b;
I am debugging a library. I can step into the code however the watch window doesn't show the values of any variables. It will display a message in the value field:
Code: m_pParentCXX0017: Error: symbol "m_pParent" not found
Interestingly it does show values for local variables in that function but not member functions. Most of my data members are member function though that I want to debug. I am using VS2010.
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:

I have counted my braces and it look to be correct but I am seeing double.. I am getting the "end of file found before the left brace.. do I have one in an incorrect place?
#include <iostream> #include <string> #include <fstream> #include<cmath> using namespace std;
I'm having issues with writing to a file. more precisely, i'm trying to determine if a set of numbers are in the file. if they are already in it, don't write to the file. if not, write to the file. My problem is my program is writing all numbers, even duplicates. The sort is working.
#include <iostream> #include <fstream> #include <algorithm> using namespace std; //Counter Stats int STR;
Currently i have a system that will store user input into a txt file, and have a function that will compute the daily sales of the month(Check by system date month) and display the sales of the day and the grand total of that month.
Take for example, the system date now check that the current month is Apr. Below are my current output:
20Apr2015 $11.5 20Apr2015 $15.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 20Apr2015 $4.5 Grand Total $45
But my desired result should be as below
20Apr2015 $31.5 22Apr2015 $4.5 25Apr2015 $4.5 28Apr2015 $4.5 Grand Total $45
i've been trying to figure out to search for a word in a text file and then display everything in the same row as the word found int ie this is whats in the file
john doe 3/21/1920 tech support review team 45,000
so user wants to find tech..and everything associated with it.
so program search for tech, when it does it then display the whole row.
john doe 3/21/1920 tech support review team 45,000
I can figure out how to search for a word, but no clue how to get it to then print out the row. This is all I can figure out to do.
ifstream FileSearch; FileSearch.open("employee"); if(FileSearch.is_open()) {string letters;// search word would be store here string row; ??stores entire row as string while(1)
From my understand the cast (reg8 *) applies to the result of the bitwise OR. But what is the left most asterisk doing?Is it just dereferencing the casted pointer?
I am creating and implementing a left and a right rotation to balance a bst into an avl tree. I have made and tried 5 different codes that are commented in the functions left_rotate() and right_rotate() but none have run correctly. Sometimes the program works, sometimes there is a segmentation fault and sometimes not all inserted numbers are shown.
avl.c
Code: #include<stdio.h>#include<stdlib.h> #include<time.h> #include "avl.h" #define N 10 void swap(int *a, int *b){
I have a board where a character is. I need to ask the user whether they want to move it up, down, left right. They are allowed to enter 3 move per turn. like up, up, left. How do I do this?
#include <iostream> #include <cstdlib> #include <ctime> using namespace std;
Having trouble getting my square to move to the left my code and instructions of what i am suppose to do is below. No sure how to move my square or if I am even going in the right direction as to writing code to do so. Note that it is only part of my code ( part 2 of project)
Part 2:
Write a graphical application that draws a square and then moves it.
Get the x and y coordinates for the top left corner of the square from the user using the get_int() member function of cwin. Get the length of a side of the square from the user using get_int() as well. Now draw the square to cwin according to the user input.Ask the user how many units to the left they want to move it using get_int() again. Then move the square, clear the screen, and draw it again.
// Part 2 // /* command output to declare the x,y value and 1 side length of a square through user interaction( Has user input intergers) */ int x_value = cwin.get_int("What is the x_value of the top left of the square?"); int y_value = cwin.get_int("What is the y_value of the top left of the square?"); int side_length = cwin.get_int("Input the length for one side of the square:"); /* Data type for the 4 corners of the square */ Point e; Point f;
This works, if just loops through till it doesn't find a space or tab than counts the index at that point then uses substr to get rid of any spaces/tabs, it's a small function and uses a goto. how to do it?
Code: string trimLeft(string lineOfCodeToTrim){ string l = lineOfCodeToTrim; int k =0; for(UINT i = 0;i<l.length();i++){
I have a piece of code in C with header files included. I run it on Mac OS X Maverick with XCode 4.6.2 installed. GCC is also installed. Note that Command Line Tools in XCode are already installed.
When I compile it, the error I receive says something like this:
add.c:1:19: error: stdio.h: No such file or directory add.c:2:20: error: stdlib.h: No such file or directory add.c:3:20: error: unistd.h: No such file or directory
However when I run it on Ubuntu, it compiles without a problem.What to do?
I am working on a couple C++ projectsfor my class. On one of my projects I get this error "identifier not found" for maximumValue. here is the code that I have done. I have got almost all the code from my text book..

#include "stdafx.h" #include <iostream> using namespace std; int main() { // demonstrate maximum int value int int1, int2, int3;
