I don't know why since I've assigned a value like that to a variable of that same type before. Unless I had garbage data somewhere and didn't realize it.

C++ :: Function To Return A Vector N Program
Oct 6, 2014My function has the following prototype:
std::vector<double> calculate_mag_response(double start_freq, double end_freq,
int N, std::vector<double> num, std::vector<double> den
The function should return a vector size N of magnitude responses in decibels of the transfer function defined by numerator and denominator vectors num and den. To adequately test, you should drive this with more transfer functions.
#include <vector>
#include <iostream>
#include <cstdlib>
#include <ifstream>

Visual C++ :: URLDownloadToFile Not Allowing The Program To Return Value
Jun 2, 2013I've been writing some code and this is part of it:
Code:
...
URLDownloadToFile(NULL, _T("http://something/something.txt"), path, 0, NULL);
return 0;
}
The file gets downloaded successfully but the downloader wont exit (return value 0). So it remains active.
I am sure the problem is URLDownloadToFile()
I am using Visual Studio 2010 Express.
C++ :: Creating A Loop To Allow User To Choose To Return To Beginning Of Program Or Quit
Apr 6, 2014I am currently having problems creating a loop that will allow my user to choose to return to the beginning of the program or quit.

using namespace std;
int main() {
int j;
do {float a;
cout << "+----Welcome to Basic Operations----+

I have not yet finished designing the interface for a couple of the operations, but right now i am hung up on trying to return to the beginning. I believe it is because the j was defined inside do and isn't carried out of the do statement for while.
C++ :: How To Access Excel File From A Program - Search It For Data And Return Info
Nov 12, 2014I have been asked to create a program that accesses an inventory file done in excel, look for a alpha-numeric code, which will be inputed by the user, and return to the user informations related to the position of that code, and informations related to the header of the column in which the code resides.
An example of the function I need the program to perform would be:
User inputs: 1429-R1
And the program returns: Marco's 6A, 8/21/2014, 3/7/2014.
using the following example of file:
Marco's 6A
Assessment 8/21/14 3/7/14
1584-R1 1584-R1 1584-R1
1461-2R1 1461-2R1 1461-2R1
1429-R1 1429-R1 1429-R1
C :: Will Return Root Statement At End Ever Return Value Other Than Value Passed To Function?
Mar 29, 2013I'm writing some functions pertaining to binary trees. I've used recursion once before while learning quicksort but am still quite new and unfamiliar with it. And this is my first time touching a binary tree. So my question: In my addnode function, will the return root statement at the end ever return a value other than the value passed to the function?
Code:
#include <stdlib.h>
struct tnode
{
int data;
struct tnode * left;
struct tnode * right;
}

C++ :: Return By Reference - Statement Doesn't Return Value Of N
Jan 11, 2015From the page: [URL] ....
#include <iostream>
using namespace std;
int n;
int& test();
[Code] ....
Explanation
In program above, the return type of function test() is int&. Hence this function returns by reference. The return statement is return n; but unlike return by value. This statement doesn't return value of n, instead it returns variable n itself.
Then the variable n is assigned to the left side of code test() = 5; and value of n is displayed.
I don't quite understand the bold sentence. Shouldn't value of n and variable n be the same?

C++ :: How To Return Value From A Pointer
Apr 1, 2013Here is what's up:
struct Square {int number, myClass* myclass};
int main() {
vector<myClass> classes;
myClass unrelated;
classes.push_back(unrelated);
Square newClass = {3, &classes.at(0)};
.
.
.
myClass is a class I have. Now, in the class, I have a function what_value and I need to get the classes.at(0) from the pointer to it in another function. But the problem is, how can I do it? I'm completely stumped, here's what I thought of:
newClass.*myclass.what_value();
And it I get an error from the compiler. Basically, how can I do this in another function with a pointer:
classes.at(0).what_value();
C++ :: Use EOF And Carriage Return Together?
Jun 9, 2013I'm going to write a program that takes string until end of file(eof). An condition must be considered and that is it must also terminate by a new line. For example when it's prompting me to enter a string if I press enter it must terminate and exit the program. How is it possible? I tried saving carriage return("") as a string then I compared it with the entered string but it didn't work.

C++ :: Return A Node Using Recursion
Mar 27, 2013So the task is to find the node with minimum value of a binary tree (not binary search tree). the input is the pointer to the root of the tree. and i cannot make recursion work when i do if conditions. here is what i have Code: /*function 3-takses as input the pointer to the root of the tree and returns a pointer to the node with the minimum value*/
CPPtr minimumvalue(CPPtr SP){
CPPtr min = NULL; //node of minimum value
if(SP== NULL){ // if there is a node, begin comparing
return NULL;
}
else{
if(SP->data<SP->left->data){ //if the node has smaller value than its left child
min = SP; //update node of minimum value

no matter where i call my function i get errors like unhandled exception at some memory. how to use recursion in this?
C++ :: Return Value For A Type Class?

C :: Function Return Code / Value?
Sep 27, 2014I have a function that needs to return a "uint8_t" value. However before doing the processing I need to perform a test on the argument to check if it's between expected boundaries. Although this function works it gives (a logical) warning that not always a value is returned although expected. What is the normal way for functions like these where I normally should return e.g. -1 in case the test doesn't succeed and otherwise the uint8_t (t) value?
Code:
uint8_t myFunc(int a) {
if (a >= 0 && a <= 100) {
// Perform actions
uint8_t = ...
return t;
}
}
