Error: version21.cpp(119,11):Case bypasses initialization of a local variable


How can i fix it

Heres the code:Not finished tho)

         }
         break;

      case 2:

          clrscr()

         cout<<"Enter The Input File(C:\example.txt): ";gets(input_file);fflush(stdin);
         cout<<input_file<<endl;
        
   }

}

Also any suggestions on how to improve the code would cool

Thanks alot

Move your variable declaration out of the switch. I always declare all of my vvariables at the top of each function, then you know where they are. Some compilers allow you to do other things, when you run up against one that doesn't, and everything is at the top, no problem, as you've found out, do it your way - bang.

cout<<"Enter The Input File(C:\example.txt): ";gets(input_file);fflush(stdin);

Should be either

cout<<"Enter The Input File(C:/example.txt): ";gets(input_file);fflush(stdin);

or

cout<<"Enter The Input File(C:\\example.txt): ";gets(input_file);fflush(stdin);

I fixed the prob....but since I am fairly new at this, im not sure how I can input the file and then encrypt whats in the file, help please


This is what I doin now...It doesnt work but I think I'm on the right track::

I think this only gets one character at a time...how can I make it get all the characters then from there encrypt

Code:

   if (infile)
         {
         	infile.unsetf(ios::skipws);

            while(!infile.eof())
            	{
               	infile >> file_ch;
               }

                string_length=strlen(file_ch)

                  	for(x=0; x<string_length; x++)
            			{
   						file_ch[x]=file_ch[x]+key;
							}
               infile <<file_ch;

         }

        infile.close();
