Where is the problem?

[murmuls404]

This program dont work.
If there is not even number after odd number,all negative numbers must be printed out from the end to beginning,otherwise positive.



#include<iostream>
using namespace std;

int sk;
int a;
bool skaitli = true;
int main()


{
cout<<"How many integers you want to input?"<<endl;
cin>>sk;
int arr[sk];
for (int i=0;i<sk;i++)
{cout<<"Enter "<<i+1<<". string number "<<endl;
cin>>arr[i];
}

for (int j=0;j<sk;j++)
{ if (arr[j]%2!=0&&arr[j+1]%2==0)
skaitli=true;
else
skaitli=false;
}

if (skaitli)
{
a=sk-1;
for (a;a==0;a--)
if (arr[a]<0) cout<<arr[a];
else
if (arr[a]>0) cout<<arr[a];
}
system("pause");
return 0;
}

Next time, please format your code to make it readable and use the code bbcodes please.
Standard C++ formatting with 3 space tabs.

To get to the point: So there must be a postive number, after a negative number to print all evens else it prints odds? May I ask the purpose of this program without looking at the code?

#include<iostream>
using namespace std;

int sk;
int a;
bool skaitli = true;
int main()
{
   cout<<"How many integers you want to input?"<<endl;
   cin>>sk;
   int arr[sk];
   for (int i=0;i<sk;i++)
   {
      cout<<"Enter "<<i+1<<". string number "<<endl;
      cin>>arr[i];
   }

   for (int j=0;j<sk;j++)
   { 
      if (arr[j]%2!=0&&arr[j+1]%2==0)
         skaitli=true;
      else
         skaitli=false;
   }

   if (skaitli)
   { 
      a=sk-1;
      for (a;a==0;a--)
      {
         if (arr[a]<0) 
            cout<<arr[a];
         else 
            if (arr[a]>0) cout<<arr[a];
      }
   }
   system("pause");
   return 0;
}

Well, one thing that's wrong is on line 11: int arr[sk];

You're not allowed to do that. You need to use either malloc ( int* arr = malloc(sk*sizeof(int));) or new (int* arr = new int[sk]). However, you then need to free(arr) (in the case of malloc) or delete[] arr; (in the case of new) to prevent any possible memory leaks.

I haven't run this, though, so I don't know if there's anything else wrong. It's just the first thing I noticed.

to computerquip

if user inputs: 2 -2 3 -5 5 2 69 -63 i have to print out 69 2 5 3 2
if user inputs 2 4 6 8 -10 8 6 -12 i have to print out -12 -10

No matter whether there is positive after negative or negative after positive.
I have to know if there is even after odd.
like this arr[j]%2!=0&&arr[j+1]%2==0

Still no one can help?:( Made a little changes.And have no idea how to make readeble with bbcode.Completily stupid..

#include<iostream>
using namespace std;


int main()


{
int sk;
int *arr;
bool paris = true;

cout<<"Cik skaitlus velies ievadit?"<<endl;
cin>>sk;
arr = new int[sk];
for (int i=0;i<sk;i++)
{cout<<"Ievadi "<<i+1<<". skaitli "<<endl;
cin>>arr[i];
}

for (int j=0;j<sk-1;j++)
{ if ((arr[j]%2!=0)&&(arr[j+1]%2==0))
paris=true;
else
paris=false;
}

if (paris)
{
int a=sk-1;
for (a;a<0;a--)
if (arr[a]<0) cout<<arr[a];
else
if (arr[a]>0) cout<<arr[a];
}
delete[] arr;
cin >> sk;
system("pause");
return 0;
}

is this what you want?

#include<iostream>
using namespace std;

void keep_window_open(){
	char ch; 
	cout<<"enter any character to continue..."; 
	cin>>ch;
}

int main(){
	int sk;
	int *arr;
	bool paris = true;

	cout<<"How many integers you want to input?"<<endl;
	cin>>sk;
	arr = new int[sk];
	for (int i=0;i<sk;i++){
		cout<<"Enter "<<i+1<<". string number "<<endl;
		cin>>arr[i];
	}

	for (int j=0;j<sk;j++){
 
		if ((arr[j]%2!=0)&&(arr[j+1]%2==0)){
			paris=true;
			break;
		}
		else paris=false;
	}

	if (!paris){
		for (int a=sk-1;a>=0;a--){
			if (arr[a]<0)cout<<arr[a]<<' ';
		}
	}
			
	if (paris){
		for (int a=sk-1;a>=0;a--){
			if (arr[a]>0)cout<<arr[a]<<' ';
		}
	}

	delete[] arr;
	keep_window_open();
	return 0;
}

[c o d e ] code goes in here then you finish with [/c o d e ]

Also you should use more meaningful variable names.
