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..
// Three numbers.cpp : Defines the entry point for the console application.//
#include "stdafx.h"
#include <iostream>
using namespace std;
int main() {
// demonstrate maximum int value
int int1, int2, int3;
I have an issue with a switch case in my program. I execute it and it does fine all the way up to where it says, "Answer (1, 2, or 3): ". When I enter 1, 2, or 3, it gives me' "Not an input choice!" from the default of the switch case.
NOTE: I use Code::Blocks on Windows XP.
Here is the code:
Code:
#include <stdio.h> #include <string.h> int main() {
I have an assignment for uni which requires the program to ask the user to input a number in for a variable to use in later equations. The assignment specifies that if the number that is input into the program is not an interger that it needs to be rounded UP to the nearest interger. e.g. 2.5 = 3, 5.00001 = 6 etc. i have identified this variable using "int" which i know makes it an interger however it also always rounds the number DOWN to the nearest interger. I was just wondering what the best way to approach this problem was. The only idea i have is to put + 0.99999 at the end of this variable when it is worked out so that if it is not a whole number it will be raised above the next interger and then rounded down however this will not work if there is too many decimal places.
Program is not finished as I can't get passed read_data
Error: "error C2065: 'fin' : undeclared identifier error C2228: left of '.open' must have class/struct/union type is ''unknown-type''
#include "stdafx.h" #include <iostream> // for streams #include <iomanip> // for setw() #include <fstream> // for files #include <cstdlib> // for exit using namespace std; void read_data(int A[], int size)
I need to keep a data structure, which has an id, an object pointer and a position. this id is used to randomize things, the object and the position is attached to this id. So which way is better?
Code: struct data { int id; ObjectBase* obj; Vector3 position; }; vector<data> vecData;
I'm writing a program to read in a Master.txt file and then update it through a Transaction.txt file that contains various transaction types [Adds (A), Deletes (D), and Edits (E1-E4)]. The records in both files are in ascending order based on Item#. Ultimately, the original Master.txt and updated Master file (Master2.txt) will be merged to reflect all valid transactions, and an errorLog.txt file will be created to indicate all invalid transactions. I feel I have all of the code written correctly, but I am still getting errors on my operands and identifiers.
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.
unsigned short num; while (true) { std::cin >> num; if (std::cin.fail()) { num = 1;
Would there be anyway for the compiler, or the language, to provide a unique ID during compilation?
I've been using UUID generators, but I've always found the approach of copy pasting from a program to code to be kind of... limiting. If I want a random number, can't the compiler guarantee this for me?
It already does the same thing for anonymous namespaces, so...
I have some code does not compile. I think it's missing an included library, but not sure.
In the int main() block of code, the following three items give errors:
1. Mtrx (the one following "new") - Error: expected a type specifier 2. result - Error: expected a ";" 3. &result - identifier "result" is undefined
Below is the code with the head to show you what has been included:
HTML Code: #include <iostream> #include <iomanip> using namespace std; #include <limits.h> // create the structure of the matrix struct Mtrx { int numRows; int numCols; float array[101][101];
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 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 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'm trying to create a template binary search tree and I'm getting all these vague errors that I have no clue how to solve. I've narrowed it down to my findMax and findMin functions but i can't figure it out any further than that.
template<class T> class BinarySearchTree{ private: struct BinaryNode{ T data; BinaryNode *left; BinaryNode *right;
[Code] .....
and here is are the errors I'm getting from this header file.
1>------ Build started: Project: Programming Assignment 2, Configuration: Debug Win32 ------ 1> main.cpp : error C2143: syntax error : missing ';' before '*' : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int : error C2065: 'T' : undeclared identifier
Each of my header includes is protected by directives. I think I don't have to include Boolean in my work space because it is already included in the external dependencies section. and the Boolean.h is in the include path.
I'm having some trouble printing the duplicates found in an array. Specifically, when the value is at more than 2 positions. So if the value 3 is at position 1, 10, and 11 it'll print three messages instead of two:
value 3 at position 1 is also at position 10 value 3 at position 1 is also at position 11 value 3 at position 10 is also at position 11
instead of
value 3 at position 1 is also at position 10 value 3 at position 1 is also at position 11
This is real simple problem, but I can't seem to figure it out. I've been trying to implement another array to 'remember' the encountered position, but I haven't had any luck.
Code: for(i = 0; i < num_count; i++){for (j = i + 1; j < num_count; j++) {if (num[i] == num[j]){printf(" value %d at position %d is also at position %d", num[i], i, j);}}}
For some reason my code is not couting right. My function is supposed to decipher some code that if it has multiple same chars then it drops one. Example aabbyfkk --------> abyfk. But it couts abyffkk . For some reason it is not getting rid of the extra f and k chars.
string decrypt (string encrypted) { string deleted, tmp; int i, pos, n, j=0, z; tmp=encrypted;
I created a very basic program which contains a vector (my vector) that holds 0, 1 and 1. This program compares each element in the vector. If the element after the one currently being compared is equal to it, it outputs "repeat found!" Now this all works perfectly, but my next step was to erase the repeated one. Everything was working up until the delete step. I get a weird error that says "vector iterator not dereferencable" .
// vector::begin/end #include <iostream> #include <vector> using namespace std; int main () { vector<int> myvector;
How to return a message saying that the value searched for is not found. We had to pull the data in from a .dat, i won't let me attach it as a .dat so I attached it as .txt. I know my it's sloppy. I usually clean up what I can once it is working properly.
#include <iostream> #include <iomanip> #include <fstream> #include <string> using namespace std; int ccnt; int size = 10;
