Book Error????????

[iamyiyaj]

So i retyped this book code in on a c++ compiler and it gave back an error though in the book there is proper output.

 #include <iostream>
using namespace std;

 int main()
 {
int set[8] = {5, 10, 15, 20, 25, 30, 35, 40};
int *nums = set; 


cout << "The numbers in set are:\n";
cout << *nums << " "; 
while (nums < &set[7])
 {
  nums++;
 cout << *nums << " ";
 }

 cout << "\nThe numbers in set backward are:\n";
 cout << *nums << " "; 
 while (nums > set)
{

 nums−−;
 // Display the value pointed to by nums.
cout<<*nums<< " "; 
}
 return 0;
 }

It did not take nums-- but how else is it supposed to reverse the order??

So i tried instead --nums and that worked but why would the book have it the other way? Do compilers not accept minus in front or something?

[Repeater]

nums−−;

See those two symbols there, that look like this: −− ?

They're not the minus symbol. You've cut and paste this from somewhere, and instead of - you've got −.

Only the actual - symbol is accepted.

You've used some kind of fancy "dashes" instead of the plain old minus sign for your --. Just try retyping it.

oh....wow.
