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?
