output problem

[wizo0o]

hey ppl

i dono wats wrong with this ??
could any one tell me the output of this & what are the values of x, y, z when the program ends?

#include <iostream>
using namespace std;

void function1(int &, int &);
int function2(int &);
int function3(int , int);
void function4(int, int, int);

void main()
{
int x = 9, y = 7, z = 5;

for(int i = 0; i<= 5; i++)
function1(x, y);;

z = function2 ( y );

if((z>=10 && x<7) || y!= 5)
{
y = function3(x,9);
x = function3(y,9);
}
else
z = function3(z,x);

function4(x, y, z);
system("pause");
}
void function1(int &a, int &b)
{
a++;
b--;
if(a == b)
a = 2*b;
else
b = a%2;
}
int function2( int & a )
{
a+=2;
return 10;

}

int function3(int a, int b)
{
return a*2+b/2;
}

void function4(int a, int b, int c)
{
cout << "The Result is: " << (a+b)/c << endl;
}

Fix the errors (main returns an int) and then build it and run it.

i asked my teacher he told me its ok like this

ust find the output ??

[wizo0o]

its kinda tricky question

[Peter87]

Why don't you just run the program and see what the output you get?

[wizo0o]

i got 10 but am not sure !! dat why i am asking
what about x , y ,z ?? when the Program ends ???

[Moschops]

mebbe u cud put in like cout << x; when u want no wat x is

[wizo0o]

when i put it at the end i get an error !!!

Why are you returning a 10 in function2(), instead of the actual results of a+=2, which in this case, would be a 9?

[wizo0o]

i didnt wrote the code its not me .. i just have to find x , y, and z !! (when the Program ends)

@wizo0o

I added cout's to the functions to show what the values are in each. Pretty much what Moschops was telling you that you should do. I print out what function you're in, and the values. For the final answer, remember that integers are whole numbers, so you will not get a point something.
