of C
Questions
and Answers
1. Advantages of structured programming
[SEE 2075] [SLC 2066]
a)
It is easy to design code and test
the program modules independently
b)
It is possible to use a single
module in different in different places which reduces program codes.

5. Variable
[SEE 2073] [SLC 2071 S] [SLC 2070] [MFT
2075]
A variable is a location in the
memory of a computer whose value may change during the execution of program.
6. Constant
Constant
are the values that do not change during the execution of a program.
7. Operator
[SQE 2075K]
Operators
are special symbols that are meant for specific tasks or operators.
8. Logical
Operator [SEE 2075]
The
operators used for logical operation is called logical operator.
9. Loop
[SEE 2073] [SLC 2068] [SLC 2067 S] [SLC 2070 S]
A
set of statements which is used to repeat a block of statements for a specific
number of times or as long as the condition is true/false is called loop.
