You're doing it the hard way in C anyway.
Try strchr()...

The table I looked it up in, and don't have it handy now, explained that strchr() is available in both Java and C++.

I'm not a Java programmer, though I've debugged quite a bit of Java code.

Do you know how to do a google search on strchr? If this isn't a homework assignment, it's the better way to do this.

If this is a homework assignment, then you should consult with your instructor, mentor or teacher's aid for help on this.

Java unlike C++ has regular expression support, though c++ 11 and boost library has it

import java.util.regex.Matcher;
import java.util.regex.Pattern;
class PasswordValidator{
 
      private Pattern pattern;
          private Matcher matcher;
 
          private  final String PASSWORD_PATTERN = 
              "((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{6,20})";
 
          public PasswordValidator(){
                  pattern = Pattern.compile(PASSWORD_PATTERN);
          }
 
          /**
           * Validate password with regular expression
           * @param password password for validation
           * @return true valid password, false invalid password
           */
          public  boolean validate(String password){
 
                  matcher = pattern.matcher(password);
                  return matcher.matches();
 
          }
      public static void main(String arg[]) {
          PasswordValidator pv = new PasswordValidator();
          // test 1
          String pw = "dharmac1A@";
          if(pv.validate (pw)) {
              System.out.println("Valid");
          } else {
              System.out.println("InValid");
          }
          
       // test 2
           pw = "iamnotvalidpassword";
          if(pv.validate (pw)) {
              System.out.println("Valid");
          } else {
              System.out.println("InValid");
          }
          
       // test 3
          pw = "dharmatejachalla";
         if(pv.validate (pw)) {
             System.out.println("Valid");
         } else {
             System.out.println("InValid");
         }
          
      }
}
