C :: Return A String To Then Call It On Main Function?

May 26, 2013

const char* coiso(int chave){
char str [50];
sprintf(str,"%d",chave);
char txt[50] = ".txt";
strcat(str,txt);

C++ :: Allocate Memory In A Function And Call From Main

Aug 30, 2013

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.

C :: Create Array Of Integer - Function Call In Main

Feb 2, 2015

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.

C++ :: Keyboard Function That Is Called In Main Function To Make Shape Move

Jan 19, 2013

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.

C :: Main Function Does Not Return Any Values When Calling Other Function?

Jun 9, 2013

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[] ) {

Visual C++ :: Error C3867 Function Call Missing Argument List For Calling Thread Function

Mar 19, 2013

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.

C++ :: Possible To Change Value Of Variable In Main Using A Function?

Jan 30, 2014

I'm currently writing a poker game and am trying my best to avoid using global variables. I have a few variables in int main() which i was hoping to use to store the value of each players hand. I then created a function which calculates the value of the hand but cannot get this value back into the main function.

For example:

Code:
#include <iostream>
using namespace std;
void getValue(int value) {
value = 4;

[Code] ....

Is there any way i can get the value of value using this function? If not what can I do?

C :: Passing Variable From Outside Function To Main?

Nov 8, 2013

This code is for a program that allows you to play a guessing game or arithmetic game and shows your total score from both as you go along. The program works fine the only problem I'm having is with the score. Is there a way to call the score value from the outside function into main?

Code:
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
//prototype functions
void menu();

[Code] .....

So trying to pass the value of score from the outer function int guessGame() into the score print statement in choice 3 of the main function? Oh and the "17 -turn_count" was just part of the requirements of the assignment.

C++ :: How To Make A Shape Outside Of Main Function

Sep 8, 2014

I know how to define a shape and attach it to a window as follows:

#include <Simple_window.h>
void cir() { Circle c(Point(100,100),50); }
int main() {
Simple_window win(Point(100,100),600,400, "test");

Rectangle r(Point(100,100),Point(300,200));
win.attach(r);
win.wait_for_botton();
}

But how to define a shape (say a circle by that cir() function which is) outside of the main() function? And how to attach it to be visible on window win?
