C++ :: Match Word To Definition Hangman Game
Jun 25, 2014Basically I have a text file called words. I'm supposed to extract a word randomly from the file and have the user guess the word according to the definition.
I'm having trouble matching the definition to the word from the text file.
Here's my code:
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int number;
int count = 0;
string word;
[Code] ....
Here is my text file
apple#the usually round, red or yellow, edible fruit of a small tree
boat#a vessel for transport by water
horse#a solid-hoofed plant-eating domesticated mammal with a flowing mane and tail, used for riding
television#a system for transmitting visual images and sound that are reproduced on screens
soup#a liquid dish, typically made by boiling meat, fish, or vegetables, etc.
bottle#a container, typically made of glass or plastic and with a narrow neck
barber#a person who cuts hair
toast#sliced bread browned on both sides by exposure to radiant heat
radar#a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects
red#of a color at the end of the spectrum next to orange and opposite violet

C/C++ :: GCC Compiler Does Not Detect Multiple Definition Error
Oct 31, 2012I am trying to compile the files file1.c and file2.c using Mingw (gcc)
/////////////////////
header.h
////////////////////
#ifndef header
#define header
int variable;
#endif
[Code] ....
I would have expected a multiple defnition error when linking the two .c files. as in both the files, with the 'int variable' command, the variable 'variable' is defined (memory allocated) and during linking the linker doesnot know which variable to link to.
I get an error though when i use "int variable =123;" in the header file instead of the "int variable;" statement. i dont understand as in both the cases the variable is defined (memory is allocated) and the linker should give a multiple definition error.
C++ :: Comparing Char And Int - Output Match Or Does Not Match
Feb 21, 2013My program compiles fine and doesn't have any errors so I am confused as to what the issue might be.
I have a int, which is determined by the user via cin.
I have a char, which is a random word generated from an input file.
1. I want the program to display "The word you entered does match..." if the word entered by the user is the same as the random word.
2. I want the program to display "The word you entered does not match..." if the word entered by the user is not the same as the random word.
The code I'm using for number one is
if (char == "int") cout << "does match..."
The code I'm using for number two is
else if (char != "int") cout << "does not match..."
Basically the programs only outputs "does not match" whether or not it really matches. Even if it matches, it outputs does not match.
Is something wrong with my code?

May 13, 2014say I have person 1 to person 1024
Let's say
I want to sort them from smartest to dumbest
I have very few data say
person 1 is smarter than person 23 and so on
There are many missing data
say I don't know if person 30 is smarter or dumber than person 50

C++ :: How To Match Two Rows Of Data And Return Only 1 Value
Aug 1, 2013I've got two columns of data.
Code:
int a[6]={1,3,5,8,10,12};
int b[3]={3,5,9};
int c[6]={0}; if a is equal to ANY of the data in b, then c= a*2
if a isn't equal to any of the data in b, then c=a.
Here is the answer I want
Code:

C++ :: Type Signature For Function Prototype
Mar 30, 2013The 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.....
C++ :: STL Regex Get Position Of Match Within String
Apr 18, 2013I am trying to get the position of the matches of "Un" in string "Unseen University" in c++ code using STL regex. How can I do this.
i.e. I have following:
std::vector<std::cmatch*>* matches = new std::vector<std::cmatch*>*;
intMyReturnVal = regex("Unseen University", "Un", matches);
I can access a match by
matches->at(i)
and get an Iterator to the beginning of the match by
matches->at(i)->begin()
How can I get the relative position of the match within the entire target string (i.e. "Unseen University", where, in this case, the positions should be 0 and 7)??
C++ :: Switching Function Prototype To Another Type
Mar 29, 2014This is my code:
#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.
C++ :: Class Prototype - Generic Function
Aug 20, 2014Let's first take the following class prototype:
#include <ctime>
#include <iostream>
#include <sstream>
#include <string>
#include <fstream>
class Debugger;
class Debugger {
[Code] ....
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?
C++ :: STL Regex To Match Multiple Substrings
Apr 17, 2013I am using the (fairly) new STL implementation, which I just became aware of, of regexes. Seems to be an implementation of boost::regex Anyway, I have code, which I would like to use to get ALL matches within a string.
My String is: "Unseen University - Ankh-Morpork"
My regex is (simply): "Un" ;)
using code:
const char *reg_esp = "Un";
std::regex rgx(reg_esp);
std::cmatch matches;
const char *target = "Unseen University - Ankh-Morpork";
[Code] .....
gives output:
"Un" (one line only). How do I get this to match ALL instances of "Un" (i.e. that the output is "UnUn", i.e Un two times)?
C++ :: How To Initialize Function Prototype Of Array With Zero
Apr 23, 2014We can initialize normal function prototype's parameters with zero like this:-
void output(float = 0.0, int = 0);
or
void output(int = 0, int = 0, double = 0.0);
But how do you do the same for a pointer array or simply an array?
Assume that second parameter has to be an array.
I have tried the following and it does not work:-
void output(float = 0.0, int = 0);
void output(float = 0.0, *int = 0);
void output(float = 0.0, int* = 0);
void output(float = 0.0, int[] = 0);
void output(float = 0.0, int []);
But if I skip the default declarations altogether, it works.
like:
void output(float, int []);
or
void output(float, int*);
how can I do it by explicitly writing zero, just like the first cases?
C++ :: Simplest Way To Perform Attribute Match?

C :: Variably Modified Type - Function Prototype
Mar 24, 2013Variably 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?
