  1. Hello There,

    Thanks for highlighting this and indicating about Java MCQ Interview Questions With Answers where more study and thought is necessary.

    I started to program with C and have some programming in JAVA. However, I have a small understanding problem with the following below.
    I understand that at the command “while (isspace(ch=getc(in)))” the programm reads till if founds a character that is either a ” or a blank. This symbol is assigned to the variable delim.
    Is it then correct to say that the program starts again at the same position as before and continues to read the string till “((ch=getc(in))!=delim)” is fulfilled?
    THANK YOU!! This saved my butt today, I’m immensely grateful.

    Gracias,
    Reena
