Help with Switch..

[elmoro15]

i want to write a C++ code using switch to ouput the equivalent ASCII value of digit/character entered by the user.
Sample Run:

enter a  digit/character: 5

its AScii value is 53

sample run:

enter a digit/character: @
Invalid Input

my code is :

# include <iostream>
using namespace std;

int main()
{
  int x;
  char ch;

  cout<<"enter a decimal/character"<<endl;
  cin>>ch;
  if ( ch>='0' && ch<='9') 
	  x=0;
  if (ch>='a' && ch<='z' || ch>='A' && ch<='Z')
	  x=1;
  else
	  x=2;
  switch (x)
  {
  case 0:
	  cout<<"its AScii value"<<static_cast<int>(ch)<<endl;
	  break;
  case 1:
cout<<"its AScii value"<<static_cast<int>(ch)<<endl;
break;
  default:

	  cout<<"invalid input"<<endl;
  }
  return 0;
}

when i enter a digit.. it output to me

Invalid input

but when i enter a character it works.!!!??

Because if it's not a character you always set x to 2.

if (ch>='a' && ch<='z' || ch>='A' && ch<='Z')
	  x=1;
  else
	  x=2;

else if (ch>='a' /* ... */) x = 1;
