Here is my first program, I had to use a lot of if/ else statements. For some reason the last "else" (bolded) is giving me an error and not letting me run the program.
And yes, the if else's are indented properly, because there are no errors for the first 3 unit types, only for the last one ( 'F' ), and i have them all exactly in the same format.
This code from [URL] as it is gives compile error I can't understand.
#include <iostream> using namespace std; class Rectangle { int width, height;
[Code] ....
Gives error
(g++ first.cpp) first.cpp: In function ‘int main()’: first.cpp:14:38: error: no matching function for call to ‘Rectangle::Rectangle(<brace-enclosed initialiser list>)’
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;
In this project a user needs to enter a numeric month and a year. The output is a single calendar month with the name of the month followed by a grid of the days. My issue is that my day alignment is off. for example: if you enter the month of December (12) and this year 2014 it says the month started on a Wednesady when in fact it started on a Monday. I am not sure if its my leap year calculaion or what.
I am looking to write a program that, given a particular word, looks at a plain text document and gives a list of words that appear within x words of the given word along with a count of how many times it appears.
Do I need to use regex to do the pattern matching here? Is there a particular data structure that I should use that is particularly suited to a task like this? I don't want to reinvent the wheel, it seems like there should be libraries that would already do this sort of thing but searches have turned up nothing.
I need to call one function on my C++ program. I made one root calculator for functions, but, this doesn't work.
// FUNCION QUE CALCULA LA DIFERENCIA ENTRE 2 VECTORES real mn_error_vectores(Array1D< real > &u, Array1D< real > &v) { int i; if(u.dim()!=v.dim()){ printf("mn_error_vectores() : arrays of different dimensions
I'm having this pain in the ass error (No matching function for call to Data::Data() ) on this block of code:
Etapa::Etapa(string nm, float dist, string loc, Data dt) { nome = nm; distancia = dist; local = loc; data = dt; }
[Code].....
I guess this is happening because I'm trying to give Etapa an argument of Data type and I can't do it or put it in a variable since it has 3 parameteres (mes, dia, ano).
Here are the errors: no matches converting function `concat' to type `class Dlist (*)(class List<int>, class List<int>)' error candidates are: template<class T> Dlist concat(Dlist, Dlist)
no matching function for call to `concat(Dlist&, Dlist&)'
I can't understand what the compiler is trying to tell me.
I am trying to create a `std::map` from `std:: string` to a pointer to member function type. I'm initializing the `map` with an initializer list (braced). When I compile, I get a message from the compiler: No matching constructor for initialization.
This is my code for the quadratic equation. It keeps telling me that my else is illegal since no matching if statement and my else statement is missing a statement
#include <iostream> #include <cmath> #include <string> #include <iomanip> using namespace std; int main() { string Name;
I have developed the following code for a PIC18 micro-controller. The object of the program is to compare a input value (presumably from a magnetic swipe card), represented here as scan_id, to a list of valid access ID's represented by the array valid_id. If there is a match the program will drive an output pin high to light a green LED for 20 seconds. If there is not a match the program will drive an output pin high to light a red led for 20 seconds.
The issue that I am having is that when the program is executed, the "else" case for the red LED is always selected regardless of the value for scan_id. If I change the "if" statement from == to = then the case for the green LED is always selected regardless of the value for scan_id.
#include <p18f452.h> #include <stdlib.h> #include <stdio.h> #include <delays.h> void main () { TRISA=0xFF; /* Configure PORTA<7:0> pins as inputs */ TRISB=0x00; /*Configure PORTD<7:0> pins as outputs */
We are generating emails for freshman students, however, the system probably due to server overload fails to generate some emails. So I'm working on this c code( probably was a wrong choice) to search for regexp matching the generated emails and deleting from the list of students and propective emails.
I"m currently at the stage of making sure the code can find all the matching regexp from the student list file before deleting! But the code fails to read all matching regexp?
Code: //Filename: SearchReplace.c //Usage: This searches for lines in a file containing a particular work and deletes the lines. //Licence: GNU P.L. #include <stdio.h> #include <stdlib.h> #include <string.h> #include <ctype.h>
[code] .....
What I'm missing. It recognizes some regexp and fails to recognise some. Been staring for hours!
In the above program, I define an operator<< function in global namespace which has exactly the same signature as the one define in <string> header : [URL] . In the main function, I call operator<< on cout and a string, after which I guess it would cause ambiguity. The result is out of my anticipation, it compiles and prints [hi]. So I guess my function is a better match because it does not require argument-dependent lookup (ADL). Moreover, even if I add using namespace std; at the beginning of the main function, the program still compiles and prints [hi].
In short, I have two question:
#1 : Why is my function a better match (therefore no ambiguity) in the two cases respectively (with and without using namespace std;)?
#2 : Does using namespace affect ADL? Is ADL still performed after applying using namespace, or is it not performed because the function is thrown into global namespace?
I have got 4 radio buttons on my form and & i am trying to match the text for these radiobuttons with a record in one of the database tables. Essentially I would like when the submit button is clicked to match if the selected or clicked radiobutton Text with a database record. And if this matches a messagebox to be displayed saying "match" and if not matched the messagebox should show "no match found"
in this case the "Emp_1" is the matching record , when I run my project when other options or radio buttons are clicked it executes the messageBox showing that it matches even if its not a matching record. What I am trying to say is that it does not execute the else {MessageBox.Show("no match found");} when records don't match.
For whatever reason, I get an error meassage about lines 53-57 saying there is no matching function to call to. Yet the header and the prototype are correct (I think anyways).
#include <iostream> #include <string> #include <fstream> #define N 10 using namespace std; class cust{
My load function isnt working. I've tested it and returned it as an int and it worked but when i tried to compile when i changed it to a template i started getting the errors and I'm not sure how to fix it:
all_sort.cpp:41:15: error: no matching function for call to 'load' int *value = load("./integers.txt", size); ^~~~ ./bubble_sort.h:44:4: note: candidate template ignored: couldn't infer template argument 'T' T *load(const char* x, int &size) {
[Code] ....
I'm trying to use my load function to load integers from a file into and array and then return it back.
#include "bubble_sort.h" #include <iostream> #include <cstdlib> #include <string> using namespace std; int main(){ int n, pick = 1, size = 0;
I'm having an issue coming up with an if() statement to check if a word match the one in the value of a pointer's address. So far the best I've come up with only matches the first letter of the words, you'll find it in the code below.
#include"Header.h" int Colour(struct MyStruct *ArrayPointer, int ArraySize) //ArraySize = 3 for this run. { int ColourCount = 0; for (int i = 0; i < ArraySize; i++) {
[Code] ....
An example run you can see in attached pic.
I want to have an if statement that only accepts "Red" and not the occasional "Ravaged_Anus".
I'm using MVS Express 2013, .c source files, and the C++ compiler.
