Thread: Still having problems...

I tried the changes but it still doesnt work, but now im only down to one error, parse error on line 17, but i only have 16 lines, here's the code so far:

Code:

#include <iostream.h>

class Exchg {
      public:
             void exchange (int& a, int& b) {
                  int temp = a;
                  a = b;
                  b = temp;}
int main () {
Exchg e
int num1 = 56;
int num2 = 111;
cout << "the two numbers: " << num1 << "," << num2 << "..." << endl;
e.exchange (num1, num2);
cout << "... are now exchanged: " << num1 << "," << num2 << endl;
return 0; }

ps i meant to say the book wasnt that good, maybe you can suggest a better one?

Try:

Code:

#include <iostream.h>

class Exchg 
{
       public:
             void exchange (int& a, int& b) {
                  int temp = a;
                  a = b;
                  b = temp;
             }
} // REMEMBER TO CLOSE YOUR CLASS

main () {
Exchg e
int num1 = 56;
int num2 = 111;
cout << "the two numbers: " << num1 << "," << num2 << "..." << endl;
e.exchange (num1, num2);
cout << "... are now exchanged: " << num1 << "," << num2 << endl;
}

Code:

class Exchg 
{
       public:
             void exchange (int& a, int& b) {
                  int temp = a;
                  a = b;
                  b = temp;
             }
}; /// and don't forget the closing ; either :)

It has to have a closing ";"?
Thanks! I didn't know that!
I am suprised my compiler hasn't complained about it however, because u use classes somewhat often.
