C :: Functions Disappears While Profiling
May 9, 2013I have a program which I try to clock, or profile. When I compile with -O flags some functions disappears from the out put from gprof. Is there an explanation to this..?

C++ :: Profiling Code - 4 Threads Slower Than 1
May 9, 2013I am doing something wrong since for me 4 threads perform 2 times slower then 1.I have 2 vectors with bunch of data to process, there is no concurrency (not moving elements and are independent of each other) so i just need to calculate some data from one and copy result in another.

Mar 20, 2014I'm a little confused by my programming assignment this week. I've been working at it Wednesday and I've made progress but I'm still confused as to how I'm supposed to do this. The class I made is called Stack, and it's derived from a template class called StackADT. We also utilize a class called unorderedLinkedList, which is derived from a class called linkedList.
We're supposed to implement all of the virtual functions from stackADT in the Stack class. The Stack data is stored in a an unorderedLinkedList, so what I'm confused by is how to implement a few of the Stack functions because there are no functions in unorderedLinkedList which we could call to manipulate the data.
As you can see from my attached code, I'm really confused by how I'm supposed to implement the pop() and top() functions, and I also think my initializeList() function is wrong. We don't have any similar functions in unorderedLinkedList to call, so I'm at a loss of how i'd access my unorderedLinkedList. My initial thought was to call the similar functions in the class that unorderedLinkedList was derived from, linkedList, but I'm unsure of this is what we're supposed to do, or if theres actually a way to access my unorderedLinkedList without having to use the functions from the base class.
NOTE: We're not allowed to modify stackADT, unorderedLinkedList, and linkedList.
Stack.h
#include "stackADT.h"
#include "unorderedLinkedList.h"

class Stack: public stackADT<Type>{
template <class T>

C/C++ :: Array Of Functions Pointing To In Class Functions With Arduino
May 3, 2013At the moment im trying out with pointing to an array of functions. I got this working as following:
typedef void (* functionPtr) ();
functionPtr functions[2][2]={{do11,do12}, {do21,do22}};
void do11(){DEBUG_PRINTLN("11");}
void do12(){DEBUG_PRINTLN("12");}
void do21(){DEBUG_PRINTLN("21");}
void do22(){DEBUG_PRINTLN("22");}
void loop(){
A=0;
B=1;
functions[A][b]();
}
But now I'm trying to use this to point to a function inside a class so instead of do11, i want to be able to point to Basic.Do11. Somehow this doesnt work and I keep on getting this message:
error: argument of type 'void (Basic::)()' does not match 'void (*)()'
C :: Getting Used To Functions
Jul 24, 2013So In my studying of C I am starting to come across more programs with functions in them.This particular program asks for two numbers, and calculates the sum of all the squares of the two numbers and the numbers in between them. I am confused about the get_int() function.
Code:
/* checking.c -- validating input */
#include <stdio.h>
#include <stdbool.h>
int get_int(void); // validate that input is an integer
bool bad_limits(int begin, int end, int low, int high); // validate that range limits are valid
double sum_squares(int a, int b); // calculate the sum of the squares of the integers a through b
}
[code]....
So in that get_int() function, it's pretty simple if scanf returns 1, otherwise... another while loop call the getchar() function, which is assigned to the variable ch. So say I enter 'a' for the lower limit, this is what happens:
Code: Enter the limits (enter 0 for both limits to quit):
lower limit: a
a is not an integer. It seems as if getchar() somehow "got the character" from scanf(). There's no way that getchar() could have been simultaneously reading my input, because that function is not even called until scanf has already not returned 1. So I'm confused how that happened. I was under the impression that getchar() got input from the keyboard, which would lead me to think that I would be prompted to input something again when getchar() is called, before putchar() prints the scanf input. But this is obviously not the case.
Also, I'm curious about that comment beside putchar(ch) that says //dispose of bad input. I recall a long time ago on these forums, someone told me something about how once scanf has read input, that input is like... stuck to scanf.. So does putchar() not only print the input from scanf/getchar, but also unload it from scanf, so to speak?

C :: Adding New Functions
Jul 3, 2014I am new to c and I have come across a problem when adding other functions to a programme and printing the values. The question I am attempting to solve is :
The following function computes ex by summing the Taylor series expansion to n terms. Write a program to print a table of ex using both this function and the exp() function from the math.h library, for x = 0 to 1 in steps of 0.1. The program should ask the user what value of n to use.
double taylor(double x, int n) {
int i;
double sum = 1.0;
double term = 1.0;
for (i=1; i<=n; i++) {
/*Or we could have written: */
term = term * x / i; /* term *= x / i; */
sum = sum + term; /* sum += term; */
}
return sum;
}
My code is
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
/*Taylor series for e*/
[code]....
code prints out the values for exp, but it gets stuck in the Taylor function and I'm not sure how to solve it.
C :: Passing Into Functions
Feb 18, 2013forget everything from before. It came out of confusion regard the supplier functions. dis_s() and read_s() the part functions work and are not any different really.
Code:
#include <stdio.h>#include <stdlib.h>
#include <string.h>
#define MPS 10 //Max Part Size
#define MSS 10 //Max Supplier Size
}
[code]....
when I run the dis_s() function it just prints out garbage until it segments. starts with a bunch of 0 and newlines until it starts printing locations on my computer...... it worked on campus with debian and I only copied it from gmail to my computer so I really don't understand whats up(im on mint).

C++ :: Printing Text With Functions
Feb 27, 2014Any way to make a function that prints something. i wanted to make a function for
Code:

cout << " 1. Commands " << endl;
cout << " 2. Controller Setup " << endl;
cout << " 3. Bottles of Beer " << endl;
cout << " 4. Quit " << endl;
cout << " What is your Choice - ";
cin >> userinput;
So i wouldn't have to retype it again in the loop, i would just call the function. but it seems whatever i try it doesn't display the text. i've tried making a function with no return time like this " Void Pausemenu(); " but that just goes blank.
Code:
#include <iostream>
using namespace std;
//This function displays different results based on the users input
int menu(int menuchoice);
int main()
