Is it possible to create a function that can both return and display a value. I was trying to make a program that computes and prints terms of the Fibonacci series using a recursive function.
View 3 RepliesHow to go about making a function that accepts an integer and returns a string with any one of 5 strings containing the name of the object. For example object number 3 might be "Pen". Object 4 might be "Paper".
To do this would I just use an array?
Code:
int exploder(int number,int array[]) {
int functi = 0;
int digit = number % 10;
while (number > 0) {

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;

I'm new to C programming and in my first computer science class. Our assignment was to write a program that displays each digit of an integer in English. I wrote the following but cannot figure out why it won't display zeros. When I execute and type in the number 1,000, I get "zero."
Code:
#include <stdio.h>
int main (void)
{
int x, y = 0;
printf ("This program displays each digit of an integer in English.

I'm trying to create a program that takes an integer input and displays each digit on a new line from right to left.
An example of this would be:
Enter an integer: 657
Digit (1): 7
Digit (2): 5
Digit (3): 6
So far I have this:
#include <stdio.h>
#include <math.h>
int main() {
int i, input, output;
printf("Enter an integer: ");
scanf("%d", &input);
if(input == 0)
printf("Digit (1): 0");
[Code] ....
It works perfectly fine, but I just learned that I am not allowed to use the #include <math.h> so I have to take out floor, log, and pow.
I'm pretty sure I have to do some sort of while or for loop to get the results, but how to do it.
I was trying to code a program that accepts your first name and then last name and then displays it through another function. I have checked that the assignments are between similar type of variables and pointers, but I don't seem to get it right.
When first input is taken and then second one, the first one's value changes to same as the second. E.G if first name is L and second name is S and after second input both variables, first and sec, become equal to S. Why?
Code:
#include <stdio.h>
#include <stdlib.h>
//FUNCTION PROTOTYPES
char *input(void);
void show(char *f,char *s);

I have a function that returns a char*. No problem. But I need to concatenate another array with the results of this function. I'm getting a segmentation error.

For a Homework i need to make some kind of Minesweeper but i have one Probleme one of my functions always return teh same and i cannot fin out why here is the code:
bool setzen(int x, int y){
if(feld[x][y]!=3){
return mine=false;
}
[Code]....
Thats the Part where Everything happens but the Function "bool setzen" always returns false and i dont know why.
How can I show elements of a vector that is returned by a function in main() ?
Code:
vector<int> merge_sorted(vector<int> a, vector<int> b){
vector<int>temp;
int count = 0;
if(a.size() < b.size()) count = a.size();
else count = b.size();

so in declaring a display function prototype only that displays a student test scores in the format (student name tab number of scores tab test scores )
is this right?

class StudentTestScores{

and also how do we call the display function if it is in a class from the header file onto the main cpp file.
to return the array i shall make a pointer function thats ok.. but how do I get the size return if i dont know the size?
if I need to make AXB=C and output C my new array doesnt have a size..
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.
I'm writing a function that is to return the price of something.. What would be the most appropriate return type for this? Like in Java it would be a double...
View 6 Replies View RelatedI 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(), ...);
I have a big problem with a function, I wrote this function in order to get a line from an HTML (Or XML) file, until a specified delimiter (not always or
... It can be everything..)
Here is my code :

try {
Uri uri = new Uri("http://127.0.0.1//site.html");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);

I have a matrix that contains zero and nonzero elements. I want to do a function that return 3 arrays.
The first one is for nonzero elements the second array contains the corresponding row numbers of each nonzero element the third array contains the corresponding column numbers of each nonzero element.
Write a function that computes and returns the score for a permutation, i.e. the number of reversals required to make arr[0] == 1.
HAVE TO USE FOLLOWING FORMAT:
Code:
// POST: Returns the number of reversals needed to make arr[0] == 1
// if the reversal game were played on arr
// Note: If arr[0] == 1 initially, then score(arr, n) returns 0 AND this is what i could muster;

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())

Any good function that get the length of an integer in C++
I do know of str.length(), however i want something similar for integers
Code:
#include <stdio.h>#include <string.h>
int main() {
char pin [] = {1,2,3,4};
printf("%s",pin);
getchar();
}
the above code displays random symbols as opposed to 1234
