Not exiting the minishell results in printing the current working directory twice

I am trying to implement a minishell where if the user wants to exit the programm he is asked if he really wants to exit.

Expand|Select|Wrap|Line Numbers
  1. int main(int argc, char * argv[]){  
  2.  
  3.     char cwd[256]; char input[256]; 
  4.     char *command;  
  5.  
  6.     while(1) {     
  7.  
  8.         //return user-info and current working directory 
  9.         getcwd(cwd, sizeof(cwd));     
  10.          printf("%s@miniShell:%s$ ", getpwuid(getuid())->pw_name, cwd);      
  11.  
  12.         fgets(input, 256, stdin);     
  13.         command = strchr(input, '\n');      
  14.  
  15.         if(command){         
  16.             *command = '\0';
  17.         }      
  18.  
  19.         if(strncmp(input, "exit",4)==0){         
  20.             cout << "Do you want to quit (y/n) ?" << endl;          
  21.             string isExit = "";         
  22.             cin >> isExit;          
  23.             if(isExit == "y"){             
  24.                 exit(0);         
  25.             }         
  26.             continue;     
  27.         }  
  28.     }   
  29.     return 0;
  30. }
Exiting the programm works very well but if the user chooses to not to exit the shell it results in printing the working directory in the next line twice. What am I doing wrong and how can I fix this?

What environment and IDE are you using?
