Which header file yielded this function?

I'm going to assume you have done tests in the following way-- [code=c++] #include <cstdlib> #include <iostream> using namespace std; struct Sort{ public: int arraySize; void swap(int&, int&); int partition(int[], int, int); void quickSort(int[], int, int); bool test(); }; void Sort::swap(int &value1, int &value2) { int temp = value1; value1 …

> Write the definition of a method reverse , whose parameter is an array of integers. The method reverses the elements of the array. The method does not return a value > > So far I got: public void reverse(int[] backward) { for(int i = (backward.length -1); i >=0;i--){ } …

Get rid of the paranthesis around set-- [code=c++] bool Sort::test() { Sort set; bool answer = false; [/code]

Ok I saw some weird lines in your code. It looks like you declared inner classes within the scope of your methods. I'm really not sure how Java handles that. Typically any type that is declared within a method is destroyed unless it is a valid pointer. Then again I …

There are far, [I]far[/I] more errors to that code than just the illegal start of expression warning. Fist of all I can see a nested method declaration/definition which is illegal Secondly your System statements aren't capitalized in some areas. I can see many other errors such as the System.out.println printing …

[QUOTE=TeCNoYoTTa;652137]thanks .....:D:D but i also want to know when to use it and what is it's uses[/QUOTE] A function that returns a valid reference can be treated as a lvalue. [code=c++] int& sumz(int x,int y) { int *sum = new int; *sum = x + y; return *sum; } [/code] …

You don't need to keep posting different topics about this. Since I'm not very helpful, I will for the last time point out the error then quit replying. [code=java] import java.util.*; public class IntNode { public int item; //element in list public IntNode next; //next node in list public IntNode …

I think what you mean is you want a wrapper class-- [code=c++] #include <iostream> #include <cstdlib> class SubFoo{ }; class Foo{ private: SubFoo *sub; public: Foo(SubFoo &obj) : sub(&obj){} Foo(SubFoo *obj) : sub(obj){} }; int main(){ Foo foo = new SubFoo; SubFoo sb; Foo foo2 = sb; return 0; } …

Before I give you another suggestion for simply fixing one error, I'm curious to know what kind of Linked List you want to make? It looks like you want to make a doubly linked list, but I could be wrong. It also seems that you may, instead, be making a …

Beware of stale-data declarations! Here's the code revised, but I'm not sure if it will do exactly what you want. [code=java] import java.util.*; public class IntNode { public int item; public IntNode next; public IntNode head; IntNode prev = null; IntNode curr = head; //////Constructor/////// public IntNode(int item1, IntNode next1) …

How in the hell do you divide by 7 using nothing but-- ~, ^, >>, <<, &, | -- In a set algorithm. I'm stumped. I've tried mapping out different numbers dividing by each other... it didn't work. I would map out a number subtracting from the other to see …

I think this is what you meant-- [code=c++] // Code Shark #include <iostream> #include <windows.h> #include <string> using namespace std; int main() { srand(time(NULL)); unsigned int digit = 0, digit2 = 0, correct = 0, wrong = 0; string answer; do { system("Cls"); digit = rand() % 9 + 1; …

[QUOTE=VernonDozier;648495]I imagine you want this line: [code] quarter = .25 number % quarter [/code] to be something like: [code] quarter = number / 0.25; [/code] If you have $1.78, you'll have 7 quarters, which is 1.78/0.25 (integer division truncates to 7). I don't think you want to % operator at …

[QUOTE=herms14;648813]it also doesn't work. I've tried it but my outputs are some strange symbols nothing else..[/QUOTE] Ok this is just theory but-- Why not read every value (separated by spaces) as a string then sstream them into ints and store that sstream'd value into an indice of the array?

You forgot to return when the writeLine function reaches zero. Because of that it doesn't act as a sentinel, and writeLine just keeps writing String values to the screen. Also, it's a good idea to put your code in blocks during a condition. Here's the modified code. Msg me if …

It could be that string is defined in namespace std, which you forgot to declare that you are using. Either that or declare-- [ICODE] using std::string [/icode] or-- [icode] std::string var; [/icode]

Wow sending data is that simplified in C++? My god, that is incredibly easy.

You might need to make a minor edit-- [code=java] public class Grades { public static void main(String[]args) { Instructor grades = new Instructor(); grades.congratulateStudent( 'A' ); // enter a char as parameter here, 'A', 'B', 'C' etc char grade = args[0].charAt(0); } } [/code]
