my assimeant

[moosa94]

hello everyone i have an assimeant and i face some proplem with it
the assimeant consider 5 parts

for part A ..
Write a function named 7that output the elements of an integer array.
and i write this

void outputarr(int a[], size){
for ( int i = 0 , i < size , i ++ )
cout<<a[i];}

and part b ..
Write a function named readarr that reads the elements of an integer array

void reader(int a[])
{
int i = 0;
ifstream input;

input.open(a);

while (i != input.eof())
{
input >> a[i];
i++;
}
input.close();

but i am not sure from codes
and i cant start solveing the other , i feel that i am confused
so can any one help me as soon as possible
this is the rest of the qustions


PART C consider
Write a function named maxPosition that takes an array of integers intList, and the
The index of the last element in the array(last). The function should return the Position (Location) of the
maximum value in the array (a number between 0 and last).
For example, if the following array intList :

25 99 35 40 45 50 55 888 65 70
is called with the value of last as 9 it should return 7,
but if it is called with the value of last as 6 it should return 1.

PARTD
Use the above function of part C to write a selectionsort function to sort an array of integers in
descending order (High to low).


PART F
Write a main function to test the above functions.

1. Declare an integer array named Arr with maximum size 50.
2. Read 10 integers into array Arr (call function readtarr)
3. Output the array before sorting( call function outputarr).
4. Sort the array using function selectionsort
5. Output the array after sorting( call function outputarr).

Part B:
1. input.open(a); will result in a compilation error because open expects a char* as argument - not an array of int.
2. What are you doing in reader()? You're comparing an index against the inputs end-of-file condition?
3. You should ensure to not overwrite your array boundaries. So give your function another parameter offering the arrays size in bytes. A better way would be to use f.e. std::vector. It manages its size internally.

#include <iostream>
using namespace std;
void outputarr(int list [] , int size)
{
for ( int i = 0 , i < size , i++ )
cout<<list [i]<<" " ;
cout<<endl;
}
void readarr ( int list [] , int size );
{
for ( int i = 0 , i < size , i ++ )
cin>>list[] ;
}
int maxposition (int list[] , int s , int l )
{
int max = list[s], pos=s ;
for (int i = 0, i <l , i ++)
if (list [i] > max )
{ max = list [i] ;
pos=i ; }
int temp,big,pos;
for(int i = 0 ; i<s-1;i++)
{
big = list[i];
pos = i ;
for ( int j = 0 ; j <s ; j ++ )
if ( list[j] > big )
{
big = list [j];
pos= j ; }
}
temp = list[i];
list[i] = big ;
list[pos] = temp ;

return pos;
}
int main ()
{
int m[], size, finall;
cout<<"enter the numbers please " <<endl;
cin>>size;
cout<<endl;
readarr(m,size);
outputarr(m,size);
cout<<"enter the last number please"<<endl;
cin>>finall;
cout<<"the biggest number is: ";
maxposition(m,finall,size);
cout<<endl;
cout<<"the array is : " <<endl;
outputarr(m,size);
cout<<endl;
return 0 ;
}


this is my new codes but i still have errors !?

Please PLEASE PLEASE: Use the Source Code tag: Those little button at the right of the editor field marked '<>'.

Please think about others reading and trying to understand your - and not only yours - code.

this is my new codes but i still have errors !?

And another PLEASE: Shall we guess the errors your compiler/linker will output?
