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[] ) );
the loop iterates the first time through qualifying for (count % 2 != 0) because count is at 1 so it stores the characters after the comma into tok and does it successfully according to my debugger.then the while itterates again because it doesn't qualify for the next if. this time it does qualify for count % 2 == 0 but my tok pointer is now null , how can that be? does it go null when the while loop itterates for the second time? that shouldn't be because my integer count doesn't reset?
My program will not run because of error LNK2028 "unresolved token" and error LNK2019 "unresolved external signal" and I do not know why. My teacher says that I need to make the constructor and display functions display class variables in different formats, but I do not know what to do with that. Here are my 3 files:
Header take 2.h:
#pragma once #include <iostream> #include <string> using namespace std; class Heading { private: string company, report;
[Code] ....
Here are the errors: Error1error LNK2028: unresolved token (0A0003C9) "public: __thiscall Heading::Heading(void)" (??0Heading@@$$FQAE@XZ) referenced in function "int __cdecl main(void)" (?main@@$$HYAHXZ)c:UsersOwnerdocumentsvisual studio 2012ProjectsClassLibrary2ClassLibrary2Source1.objClassLibrary2
The following code writes to a file on either local disk to a remote disk (commented out code) on Windows 7 platform.
Code: #include <iostream> #include <fstream> using namespace std; int main () { ofstream outfile;
[Code].....
The documentation does not specify what is a valid filename (path and filename). For example, will the "\server emp" path work on all operating systems to access a samba share? Does the constructor accept forward and backward slashes as folder separator on all operating systems?
How can I write my simple program so if the user enters an invalid number, The program won’t exit? I know I am supposed to use a if (cin) or if (!cin),
But I don’t know where in the program or how I should use it. Right now my Program looks kind of like this:
If (number > 1 && number < 1001) Go through some function loops Else Cout << “invalid number”;
I need to write it so when the user enters an invalid number, the program would Keep asking for the right number until it's given.
So my program is to check if a certain 9x9 sudoku grid is valid. i have to get the input through command argument. so for example.
./a.out sudoku.txt
So we have make my c program to use FILE I/O open and what not
program behavior must be as follow File does not exist.File contains something other than a sequence of 81 integers (too many, too few, non-int).
One or more of the values is not in the range 1..9 Violation of Sudoku rules (this is the big one!) In case 4, you should report the violation (or any one of the violations if there are multiple -- you do not need to exhaustively enumerate all violations).
For example: Row Violation: entries (2,2) and (2,6) are both equal to 7. (Similarly for column and box violations). All i know is that i need to make a 2d 9 by 9 array
Is this a good way of writing this program?I wanted to start fresh with my new code though and a better title.Basically, I took what I learned from my questions in that thread and managed to build a list of musical notes( octaves, frequencies, sharp symbols, basically everything ).
Code:
#include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <math.h> #define MAX_NOTES 88 /* 88 keys on a standard piano */
[code]...
I already know the frequencies are correct( they are rounded, but they should be close enough to the value ), but I wasn't so sure about the note labels. Obviously though, I'm not done with this program and I will be adding most of the functions Anduril suggested to take a text file and convert it into music. I just wanted to make sure I had everything correct before moving on. I probably didn't do the GetNextOctave() and GetNextNote() functions very efficiently so need suggestions on those functions also.
I have this piece of code in parts of my path finding algorithm
for( int head; head < q.size(); ++ head ){ walk& w = q[head];
// do manything with w if( some_condition ) q.push_back( walk( w.x + 1, w.y, head ) ); }
However I notice that sometimes w is cannot be dereferenced. It can but it throws junk number at me. Perhaps the vector is changing it size and move the whole array to a different location. Is there anyway to make sure that w is always valid ?
I just want to use w because of shorter typing and cleaner look not because of performance. I also refrain from using macro.

if I include iostream twice in my project why is that valid? Wouldn't the linker see that there are two definitions of it and report a error, but it works?
After executing the first codeline strTempW.Format(L"%c", 0xFFFF), I will get strTempW of length 1, but cannot see it first character in Visual Studio watch window.
After executing the codelilne strTemp1 += strTempW, I will get strTemp1 of length 0.
Whether 0xFFFF is taken as a valid Unicode or not?
Is there any methods to add scroll bar for group box
My code scenerio is: I have many groupbox in form, all group box will be appears in same place and also height and width is fixed. I'm doing group box visible true/false according to condition.
So some groupbox ecxeeds the width and heighto so I want to put this all in scroll Bar
