The function im having problems with takes an array where each element is an array of unsigned chars i.e. octals representing a bitmap of one of 95 ASCII code characters and searches through this two dimensional array looking for a match for a predetermined of array of unsigned chars i.e. the bitmap of a predetermined char. If we find the char the function outputs the index in the two-dimensional array where each elem. is an array of octals ELSE it return -1 i.e. when the char is not found.
I have 2 files, one .cpp, the other .h. There is a function named find_char. See INPUT and OUTPUT on line 48 in .cpp file.
The exception im getting is: font2.cpp:23:45:error: invalid conversion from unsigned char to unsigned char(*)[5]
The input type specified for my function prototype corresponding to find_char. If I put just unsigned char it doesn't fix the problem because it's an array parameter i.e. like a call by reference. I've lead myself to believe that the array variable contains a pointer to the first value in the array and so I've made function prototypes that work with a T* i.e. a pointer to type T. Making the function prototype argument unsigned char* i.e. a pointer to unsigned char simply gives me the exception: "invalid conversion from unsigned char to unsigned char*". When I have the argument be 'unsigned char' I get undefined reference to find_char(unsigned char). URL.....
#include<iostream> #include<string> using namespace std; int bin2dec(const string binarystring); // Declaration of bin2dec prototype with one string parameter int main() { cout << "Enter Q to terminate program.
[Code] .....
Right now the code is in the form of a 'const string binarystring' and were supposed to be able to use 'const char binarystring[]' and for some reason whenever i try to switch it i run into problems when referencing the main function to the int bin2dec(...) function.
I wanted to know if theres a simple way to switch the prototype to an array type of function with [] without changing the entire code.
Variably modified types are subject to certain restrictions , just as variable-length arrays are. The most important restriction is that the declaration of a variably modified type must be inside the body of a function or in a function prototype.
Code: void f(int m , int n) { int a[m][n] , (*p)[n]; p=a; //.... }
What does it mean? That we can't declare such a pointer as a global variable?

My question is regarding the GetCurrentDebugLevel function above. Ideally I would like to use just one function to get the current debug level of the class, the std::string form would be used to save the "debugging level" in a settings file and the enumerated version would for evaluation purposes throughout the program.
My question is if implementing function prototypes by return value the best way to go or should I do something else?
#include<iostream.h> #include<conio.h> int main() { setcolor(BLUE); setbkcolor(yellow); cout<<"the text in blue colour with yelow background"; getch(); return 0; }

I am trying to computed the time it takes for a projectile to hit the ground. The problem is that i need to square the input of velocity before i do the calculation. the question I have is that if it's possible to have multiple arguments inside the brackets after main.
#include <stdio.h> #include <math.h> double distance (double a, double v, double g); int square(int y); double height(double v, double a, double g); double time (double v, double a, double g); double sqrt(double num);
How to how to make a function prototype that uses variables by reference. I'm making a decision based game where two running totals of two variables (ending and morality from decisions made) will decide the game outcome. I only have a few modules put in so far and most of the "story" parts cut down here to save space. I'm also getting an error saying there is more than one instance of overloaded function for the "whatToDo" module.
// ZombieGame.cpp : Defines the entry point for the console application. // #include <stdlib.h> /* srand, rand */ #include <time.h> /* time */ #include <iostream> using namespace std; //These are function prototypes to declare the functions being used void WakeyWakey(); void TwentyMinsLater(int);
1. I cannot find a header file to #include that has the sleep function prototype.
2. When I add my own sleep function prototype, I get an unresolved external reference error (for _sleep, not sleep).
What must I #include to get the sleep function prototype? What lib must I include in the linker configuration to resolve the external reference? (I suspect that if I #include the correct header file, the second question might become moot.)
The "man page" at [URL] .... says the header file is <WinBase.h>. But #include'g only <WinBase.h> results in compilation errors.
A response marked "answer" at [URL] ..... says <windows.h> [sic]. #Include'g only <Windows.h> does eliminate the compilation errors.
But apparently that does not bring in the sleep function prototype. Neither does also subsequently #include'g <WinBase.h>. (Which seems to be #include'd by <Windows.h> anyway.)
But even with my own function prototype shown below, I get an unresolved external reference for _sleep. Is that a symptom of my problem: my sleep reference is changed to _sleep? If so, how can avoid that?
According to "man page" (see link above), the external should be resolve in kernel32.lib. And kernel32.lib does appear in the "Additional Dependencies" list under Configuration Properties Linker Input.
Since I am not using C++ features, I tried setting "Compile as C" under Configuration Properties C/C++ Advanced, to no avail.
My code....
#include "stdafx.h" #include <stdlib.h> #include <time.h> #include <Windows.h> void sleep(DWORD msec); // added later int _tmain(int argc, char* argv[])
I am quite new to C programming. Now facing lots of problem with the code below. I attempt to convert he alphabet sorting into function prototype model but still facing warning during compilation.
Besides, I wish to open multiple file at the same time as well using array looping method, but got no idea to modify it...
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{
Consider the class specification below. Write the prototype (i.e. header) of a member function to overload the insertion operator (i.e. <<). The << operator is to output the data members of an instance of class StudentTestScores into an output stream. Your definition should allow for chaining of output operations (e.g. cout << x << y; where x and y are of type StduentTestScires).
#include <string> using namespace std; class StudentTestScores{ private: string studentName; float *testScores; // used to point to an array of test scores int numTestScores; // number of test scores
For class we are required to implement a signature block on all our assignments. To do this I've created a Signature Block class, but I'm having trouble implementing it. When I try to compile in Dev C++ I get this error:
[Error] request for member 'toString' in 'myblock', which is of non-class type 'SignatureBlock()'
Here is the code:
Assignment1.cpp
#include <iostream> #include <string> #include "SignatureBlock.h" // Assignment 1: Requests user's name and says "Hello." using namespace std; int main(int argc, char** argv) { string name;// string to store user's name SignatureBlock myblock();// create a signature block object
so in declaring a display function prototype only that displays a student test scores in the format (student name tab number of scores tab test scores )
is this right?
#ifndef STUDENTTESTSCORES_H #define STUDENTTESTSCORES_H #include <string> using namespace std; class StudentTestScores{ private:
[Code]...
and also how do we call the display function if it is in a class from the header file onto the main cpp file.
I want to know how to list the all the symbols in the shared library(dll or .so file). I dont want commands like nm or objdump or depends.exe . I want to get the list of functions available in shared library programmatically at runtime (after calling loadlibrary/dlopen and GetProcAddress/dlsym). Is there a way to get the complete signature of functions in a shared library?
I have written this bit of code for the Fibonacci sequence.
Code:
9 int size=0; 10 int fib[DWORD]; 11 }
[code].....
I have tried quite few things and I am trying to change the prototype for generate Fibonacci to... int* generateFibonacci(size). I have been trying to use calloc inside generateFibonacci and then declare a pointer in main that points at the address of the pointer that generateFibonacci returns.
So i have to use these prototype functions to run loops and to pause the program, the only problem is after i select a loop option and enter a number of dots to print in the loop it goes into an infinite loop and why, also when i try using the 4 option to exit it still asks me how many dots i want to print.
I have this int type function that returns a number. It returns the value 2 for now but later it will return more variety of values. How do I use the value it returned? I'm not sure of the proper syntax.
My g++ compiler is telling me that said printTest() is not part of the class. I have presented it in header class and implemented it in .cpp class but still keep getting the error. Compile and compile error -
