Apr 29, 2013
How to ADD a call to the FindMostExpensive function AFTER the main display loop, and use the index returned to display the information about the most expensive car?

I'm trying to return a string to then call it on main function.
Code:
const char* coiso(int chave){
char str [50];
sprintf(str,"%d",chave);
char txt[50] = ".txt";
strcat(str,txt);
return str;
}
int main () {
const char* info = coiso(8);
printf("%s",info);
}
If I do a printf("%s",str) in coiso function it works but the following code doesn't work.

So my assignment is to create a program that calls for a function in main that dynamically allocates an array[3] and then have pointers with multiple levels of indirection and pass them by reference so they are not lost after the function. Here is my code:
#include <iostream>
#include <array>
#include <iomanip>
#include <string>
[Code]....
Next part is to ask user for two non-negative numbers and then get the length of those numbers and create an array. for the size of each number they input. Then to separate those numbers and add the cross-sums.

I'm writing code to create an array of integer and let user input choice to display, replace, add new element, etc.I created a header file in the header file there's a function:
Code:
int display_one_element(int* array, int num_of_elements, int position) {
if(num_of_elements < position || position < 0) {
printf("Position out of bound.
");
return 1;
}
return array[position-1];
}
in main I write a function call:
Code:
display_one_element(array, *p_num_elements, position);
My code seems to work fine but there's an error message right next to my function call:
1.too many arguments provided to function like macro invocation
2.Expression result unused
I tried to move the function from header file to c source file. but other functions in the header file works fine and this doesn't work with the error message.

I would like my program to display other functions in the int main function. For example, this is what my program looks like:
int Function1(int &var1, int &var2, int &var3) {
cout << "blah blah blah" ;
cin >> var1 ;
var2 = var1 * 3 ; //example
var3 = var1 * var2 ; //example
if(blah blah blah)

I have a for loop, and after this loop, I am calling another function that wakes a thread S, and then thread S carries on its execution.
Code:
for (k = 0; k < num_msg; k++) {
if( (c % Messages[k][2] ) == 0 ) {
printf("
%d, act, %d
[Code]....
I am getting an anomalous output. Before all the iterations of for loop could finish, the program enters into the invoke_thread_S() and I can see the remaining iterations of for loop happening after thread S is finished.
What could be the problem here. Can I put a 'sleep' before I enter into invoke_thread_S() function, I tried it with a very small amount (in nano seconds), but that did not solve the problem.

I am trying to display the following arrays.
int a[4]={5,9,2,10}
int b[3][3]={1,2,3,4,5,6,7,8,9}
int c[2][3][2]={1,2,3,4,5,6,7,8,9,10,11,12}
Using these call statements
Display (a,4);
Display(b,3);
Display(c,2);
I'm not sure on how to put this all together but this is what I have so far.
Code:
#include<iostream>
#include<iomanip>

using namespace std;

I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:
#include <iostream>
#include <string>
using namespace std;
#include "FerryBoat.h"
int main() {
//create a constructor for a ferry boat
FerryBoat myBoat('B', 20, 'A');

Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) {
switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.

I am trying to create a loop to call in the entries from the text file named Set. The entries of Set.txtare :
1 2 3
2 4 5
and so on .. (64 such combinations)[/CODE]
It basically means the first combination for testing is 1 2 3 and next has to be 2 4 5 and so i have 64 such entries defined in set
My test files are located in D://data// and are named tst_data1 to tst_data64.
I created a loop for test set but its incorrect
Code:
// loop for test samples
char basefilename[] = "D://data//";
char , testFilen[160], numiChar[10];
for (int i=1; i<=64; i++) {
strcpy(basefilenme, "D://data//");
strcat(testfilename, Set[]);
[Code] .....
How can i call the Set .txt and how to define it.

The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {

I'm writing a program that will display 70 random temperatures, using an array that stores each number. They are going to be divided into weeks (7 temperatThe loures per line), and before displaying each of the seven temperatures, I want to first display the week #. The loops I'm using work, however the variable 'i' always first displays 2, and then counts. The loop initializes it to 0, so I don't know why it's immediately obtaining a value of two. The code is posted below.
Code:
static void DisplayTemps(int[] a)
{
Console.WriteLine("Su M T W Th F S");
for (int i = 0; i < a.Length / 7; i++)
{
Console.Write("Week {0} ", i);
for (int j=(i * 7); j < a.Length; j++)

We were asked to make a program which displays the prime numbers within the range you inputted... like for example i entered 20 as the upper limit and 1 as the lower, then the program must display all prime numbers within 20 and 1..
and so my problem is, i get to display the prime numbers, but 2, 3, 5, and 7 can't because it think it's with the if statement i made within the loop? (Code below)
#include<iostream.h>
#include<conio.h>
void prime (int up, int low);
main() {
clrscr();
int Upper, Lower, i;

I searched the web for error: C3867... and the discussions where murky or obscure.
My code excerpt is:
#pragma once
#include <windows.h>
#include <stdlib.h>
#include <process.h>
void PutUpfrmIO(void *);
namespace WordParsor {
[Code] .....
I get the generic message:
error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.
One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.
