Predefined Characters in C Type Please make sure the program

Predefined Characters in C Type. Please make sure the program compiles thanks :)

// This program reads one character from the keyboard and will // - convert it to uppercase, if it is lowercase // - convert it to lowercase, if it is uppercase // - display a message, if it is not a letter of the alphabet #include #include using namespace std; int main() char c coutc if (isalpha(c)) //check to see if it is a letter of alphabet if (isupper(c))//check to see if it is uppercase cout

Solution

#include <iostream>
#include <cctype>
using namespace std;

int main()
{
   char c;
   cin.get(c); //cin.get() input the character which can be of any type
  
  
   if(isalpha(c))
   {
       if(isupper(c))
       {
           cout<<\"Your character \"<<c<<\" is in uppercase\";
           c=tolower(c);
           cout<<\"\ Its lowercase is \"<<c<<\".\";
          
       }
       else
       {
           cout<<\"Your character \"<<c<<\" is in lowercase\";
           c=toupper(c);
           cout<<\"\ Its uppercase is \"<<c<<\".\";
       }
   }
   else if(isdigit(c)) //isdigit() checks if character is a digit
   {
       cout<<c<<\" is a digit\"<<endl;
   }
   else if(isspace(c)) //isspace(0 checks if the character is a whitespace)
   {
       cout<<c<<\"The character you entered is a whitespace\";
   }
  
   return 0;
}

output:
