C++ :: Function Returns Values After Loop Done

May 15, 2013

I am writing a program with a function that includes a long loop. I need this function to return a value when each loop is done, to send this value to output, in order to follow the progression. But I don't know how to do it in easy way. The function is like follow:

int goC(){
... // some local value definition
for(int i = 0; i < 1000; i++){
... // a lot of calculations done here
return i; // -> return the value after each loop is done
}
}

Here it only returns one value, i = 0. Clearly it's wrong.

C# :: Accept Two Input Parameter And Returns Two Out Values

Jan 26, 2014

class Program {
//Accept two input parameter and returns two out value
public static void rect(int len, int width, out int area, out int perimeter) {
area = len * width;
perimeter = 2 * (len + width);

[Code] .....

why is the static keyword required in the method signature for the rect() method. It will not compile if it is absent. why?

the same is true for this example:

class Program {
static void printvalues(params int[] passedin) {
foreach (var printthis in passedin) {
Console.WriteLine(printthis);

[Code] ....

This code won't compile without the static keyword in the printvalues() method signature. why?

C++ :: Function That Returns Max Of A Variable Number Of Scalars

Oct 23, 2014

I need to create a function that takes as an input a variable number of scalars and returns the biggest one. Just like std::max() does for 2 elements, but I need it for an undefined number of elements, can be 2, or 5, or 10 etc.. How to approach this?

What I need it for: I'm working with a bunch of vectors, maps, etc. and I need to find out which has the most elements. So I was thinking that I should end up with something like

int biggest = max(vector1.size(), vector2.size(), map1.size(), ...);

C :: Write A Function That Finds Integer In Array And Returns Its Corresponding Index

Mar 20, 2013

I have an assignment which requires me to do the following:

Required to write a function that finds an integer in an array and returns its corresponding index. The function must be called findNumber. It must have FOUR parameters:

- The first parameter is the array to be searched
- The second parameter is the integer to be found within the array
- The third parameter is the size of the array
- The fourth parameter is an integer that indicates whether the array is sorted. A value of 1 means the array is sorted; a value of zero means the array is not sorted.

Since a function can only return one value(To return the position of a required integer in an array in this instance) I have tried to make use of pointers to try and return a value stating whether the array is sorted or not.This is my code : (It compiles perfectly but it does not produce any outputs)

Code:

#include <stdio.h>
#define SIZE 10
size_t findNumber(int *sort, const int array[],int key,size_t size);
int main(void){
int a[SIZE];
size_t x;

C++ :: Recursive Boolean Function - Compare Two Stacks And Returns True If Identical

Oct 21, 2014

The question is to write a recursive boolean function that compares two stacks and returns true if they are identical. This is where I get stuck:

If the top items of both stacks are the same, the recursive call always returns true, because 'true' is saved on top of the return stack.

Here is my code:
template<class Type>
bool identicals(stackType<Type> s1, stackType<Type> s2) {
if(!s1.isEmptyStack() && !s2.isEmptyStack()) {
if(s1.top() != s2.top())

C :: Returning Values From While Loop

Jul 13, 2013

I am currently doing a bodyfat calculator for a course in school.I'm having a problem getting an output returned from my while loop, which determines the user's gender by user input.My function (outside of main) is currently:

Code:

char gendercheck(gender){
while (true) {
gender = _getch();
if (gender == 'M' || gender == 'm') {
system("cls");
printf("Your selected gender is male.");
break ;

[code]....

My failed tries include "return gender" and "return genderpicked" statements in both the if-functions and the loop itself, which I have deleted since that didn't work. My goal is to get a character stored in gender, so that I can use the information of the user's gender in my main function from this point and onwards.

MY MAIN IS:

Code:

int main() {
char *genderpicked ;
char gender ;
genderpicked = &gender ;

[code]....

C/C++ :: Loop Not Comparing Values Correctly?

May 12, 2014

So, I have the beginnings of a rock paper scissors game which i have created before in Java, and i am attempting to create it in c++.

Problem is, the function "int checkConvertInput" containing a loop to make sure input is valid, is not exiting the loop. As far as i can see the two strings are not comparing. Is there a library function for this? I know C had strcmp but i am not sure if it applies here.

#include <iostream>
#include <string>
#include <vector>
using namespace std;
int checkConvertInput(int playerSign, string signs[]);

C/C++ :: Storing Values In Arrays Using For Loop

I am trying to create a program that will give me an value for a chosen from the user array ut I believe the program I've made does not recognize the values of the previous arrays. (Here is my program):

#include<stdio.h>
int main() {
int n;
int i;
int j;
float c;
float a[10000];

[Code] ....

There must be problem cause every value I give n(only for n=1 the answer is correct) the result is "a[n] is -inf"

C++ :: Adding Up Values Of Dice Rolls In A While Loop

Feb 19, 2013

I'm having a problem adding up the values of the dice rolls in a while loop. The program will only store the last value so how would I get it to store multiples values? Here is my program thus far. I would try an array but we haven't gotten to that yet.

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main() {
int die_1=0, die_2=0, total_score1, total_score2, player1score;
char enter;

What operators or equation I should use to accomplish this?

C/C++ :: Finding Sum Of Values Entered By User In While-loop?

Aug 26, 2014

Keep track of the sum of values entered (as well as the smallest and the largest) and the number of values entered. When the loop ends, print the smallest, the largest, the number of values,and the sum of values. Note that to keep the sum, you have to decide on a unit to use for that sum; use cm.
