C++ :: Passing Array To Function - Error C2664
Jun 8, 2013
I've been trying to work fix this piece of code to put into a project but I could not get it to work. I keep getting this error C2664: 'SumOfNumbers' : cannot convert parameter 1 from 'int' to 'double []' . I've worked every thing piece by piece but when I try to pass the array to the function I get the error and don't know what it means. Does C++ not allow what I'm trying to do?
Code:
#include <iostream>
using namespace std;
void SumOfNumbers(double Nbr[], int size);
int main()
[Code] ....

Working on a basic class program and I'm generating two compiler errors that I'm not sure how to fix. Header file, implementation cpp and main cpp are shown below. The specific errors are shown after the code.
Header file Code:
#include <iostream>
#include <string>
#include <cstdlib>
#include <iomanip>
using namespace std;
[Code].......
The file generates the second error, C2228, at lines 37-41 and 43. Basically where I tried using the second created object. Error message is "left of '.setFirstName' must have class/struct/union"

My professor wants me to write a program that will read from a dat file, and produce an output on the screen based on the file. I don't understand why I am getting this error. I suspect it has something to do with the number of characters I've told it to read.
#include<iostream>
#include<iomanip>
#include<fstream>
#include<assert.h>
#include<string>
using namespace std;
using namespace System;
struct TStudent {
string month[10];
[Code] .....
I noticed I had a 2 beside girl, after I removed it, it still didn't fix my problem.

I'm working through the Let us C book. One exercise asks me to collect int and float , then pass them to a function that gets product of these and returns it to main. My code looks like this:
Code:
#include <stdio.h>#include <stdlib.h>
main()
{
int a;
float b, c;
[Code]...
So while compiling i get an error about conflicting types for product. I tried to google that error but couldn't understand what's the problem. My only clue is that i can't pass int and float to a function at the same time... Could that be it?

This is my question : Define a class named HOUSING in C++ with the following descriptions:
Private members
REG_NO integer(Ranges 10 - 1000)
NAME Array of characters(String)
TYPE Character
COST Float
Public Members
-Function Read_Data( ) to read an object of HOUSING type
-Function Display() to display the details of an object
-Function Draw Nos( ) to choose and display the details of 2 houses selected randomly from an array of 10 objects of type HOUSING Use random function to generate the registration nos. to match with REGNO from the array.
Now I' trying to do this by this way
Code:
#include <iostream.h>
#include <conio.h>
#include <stdlib.h>
class housing {
private:
int REG_NO;
char NAME[10];
[Code] .....
I am trying to pass the entire array of object in DrawNos(). but getting compilation error -
32: 'housing:rawNos(housing * *)' is not a member of 'housing'
48: Structure required on left side of . or .*
What is the problem? How can I pass the array of object in function and use it.

I want to use one median function "selectfunction" to choose one of the 2 other functions at random to pass my 2-dim array to the selected function. There is a problem in the median function
#include <iostream>
#define random(x)(rand()%x) // for random number between numbers of 0 and 1
using namespace std;
void proc1 (int iArray[][2]);
void proc2 (int iArray[][2]);
void selectfunction(int iArray[][2]);
int A[4][2] = {{1, 2} , {3, 4} , { 5, 7} , {8, 1} };

I wanted to print the values of a array from a function by passing the array as well as the number of elements to be read. For a single dimensional array, this is how i have written it. It's pretty straight forward. I want to read 5 elements from the 5th element in the array.
Code:
#include<stdio.h>
void display(int array[],int size) {
int i;
[Code]....
With this code I want to print the five elements from the element present in [0][4].
But shows an error that
Code:
D:BennetCodeblocks CLearning CSingleDimentionalArray.c||In function 'main':|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|18|warning: passing argument 1 of 'display' from incompatible pointer type [enabled by default]|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|2|note: expected 'int (*)[10]' but argument is of type 'int *'|
||=== Build finished: 0 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|
I know when you pass a array as an argument it gets decomposed into a pointer, but with a multi-dimensional array this is not the case. how this works for mult- dimensional array's?

I'm wondering if it is possible to pass a 2d array to a function where the size of the array is not known at runtime.
I've tried
function ( array[][6] ) ;
But the size of the array has to be constant so it cannot be declared later.
I've tried using a template but you still have to declare the size of the array at runtime. Is this even possible at all?
The only other way I can think of is using a dynamic 2d array but how to create one and manipulate it.

I want to pass array to function, to fill array with new values and then to print the array in the main. But I have problem because it prints me just array of zeros. Maybe the concept is wrong, I'm new with passing arrays to function.
function:
Code:
void printSum(int *return_array) {
int return_array[3];
int i;
for(i = 0; i < 3 ; i++){
return_array[i] = 5;
Code:
void printSum(int *return_array);
int main {
int m_return_array[3];
int i,j;
for(i= 0 ; i < 3 ; i++){
m_return_array[i] = 0;
} printfSum(start,m_return_array);
[Code]...

I need to pass a 2D array to a function. I want to know, where I may have made a mistake. This is the piece of code that I found on the web, and I am using it to allocate my 2D array.
Code:
signed char allocate2D( int** arr2D, int rows, int cols )
{
int i;
arr2D = malloc( rows*sizeof( int* ) );
if( !arr2D )
return -1;
[Code]....
My main function passes the 2D array to the function
Code: signed char read_root_message_file( int **Root_Messages, int *num ) This is how I pass the array in the main function to the above function:
Code:
int main( int argc, char *argv[] )
{
int **Root_Messages;
...
...
Root_Messages = NULL;
read_root_message_file( Root_Messages, &num_root_msg );
[Code]....

I am following a tutorial and the topic was passing array to function so i tried to do a BMI calculator by myself. I am using code blocks to compile the codes, it is actually working while using compiler's run button. But when I open the exe file, its closing the window after entering the persons' weights and heights. Here is the code
Code:
// Passing array to function example BMI calculator of n person
#include<stdio.h>
#include<math.h>
void assess(float bmi[],int a);
int main(void){
int n,i,j;
}

I was trying to pass the following 2-dimensional array to a function called jac_inv
jac_inv(jac,3);
where jac is a 3x3 matrix
function is as follows:
void jac_inv(int *jac, int m) {
double determinant=0.0;
for(i=0;i<m;i++) {
for(j=0;j<m;j++) {
j_inv[i][j]=jac[i][j];
[Code] ....
However,I get the following error
invalid types 'int[int]' for array subscripts
Is it with regard to passing a multi dimensional array to a function?

I have tried to pass an array to a function. Why my code doesn't work for a[1][0], a[1][1] etc.
Code:
#include <stdio.h>
int i=0;
int j=0;
int main(void){
int a[3][3]={1,2,3,1,2,3,1,2,3};
void f(int a[3][3]);
[Code] ....
I think my problem is with the for loops. I will try to find the error a bit more.

Write a program that inputs 10 integers from the console into an array, and removes the duplicate array elements and prints the array. By removing, I mean that you should make it appear as if the elements hadn't been there. You may assume that all the integers are between 0 and 100, Write at least 1 function in addition to the main function, and pass an array into that function as a parameter. e.g.
Please enter your 10 numbers: 1 2 3 4 5 6 7 8 9 10 The array contains: 1 2 3 4 5 6 7 8 9 10
Please enter your 10 numbers: 1 1 3 3 3 6 7 8 9 9 The array contains: 1 3 6 7 8 9
Please enter your 10 numbers: 1 1 1 1 1 1 1 1 1 1 The array contains: 1
The bolded area is where I'm having trouble. How I can go about doing this, passing an array into the function as a parameter?
Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main () {
const int MAX = 10;
int a[MAX] = {0};
int i;
[Code]...

I am trying to pass a dynamic array to a function which will:
- Copy the contents of the array to a temporary dynamic array
- Change the array passed in to one size bigger
- Copy the elements from the temp array back into the newly changed array
- Insert an item into the last spot of the array
Here is my code:
#include <iostream>
using namespace std ;
void make_array ( int Old [] , int & old_size , int toInsert ) ;
void zero_array ( int arry [] , int arry_size ) ;
void print_array ( int arry [] , int arry_size ) ;
[Code] .....
The output seems like a memory address but is just a very large number, what have I done incorrectly to cause this?
