a) Why
is $(dollar) sign followed in the function name?
Ans: $(dollar) sign followed in
the function name because the function returns string value.
b) What
will be the output of the program when it is executed?
Ans: The output is
CBR
c) What
will be the output of the program when FOR loop is changed as FOR I= 1 TO K
STEP 2?
Ans: The output is
RBC
d) What
is the name of sign “+” used in the program and what operation does it perform?
Ans: The name of sign “+” is
string operator and it is used to join the string i.e. string concatenation.
