Question

9 Write a short note for the following: a. Difference between compiler & Interpreters. b. Usages of Modulus Operator with example. c. Examples of Logical operator's rules in Programs. d. Default values taken in "For Loop"

Answer 1

A)the differenc b/w compiler and interpreter

BASIS FOR COMPARISON	COMPILER	INTERPRETER
Input	It takes an entire program at a time.	It takes a single line of code or instruction at a time.
Output	It generates intermediate object code.	It does not produce any intermediate object code.
Working mechanism	The compilation is done before execution.	Compilation and execution take place simultaneously.
Speed	Comparatively faster	Slower
Memory	Memory requirement is more due to the creation of object code.	It requires less memory as it does not create intermediate object code.
Errors	Display all errors after compilation, all at the same time.	Displays error of each line one by one.
Error detection	Difficult	Easier comparatively

B)modulus operator

4%2=0 here ans is 0 and 4%3=1 here ans is 1

here modulus operator returns reminder of divisoin

D)the default value forloop is 1

C)

Two or more relations can be logically joined using the logical operators AND and OR. Logical operators combine relations according to the following rules:

• The ampersand (&) symbol is a valid substitute for the logical operator AND. The vertical bar ( | ) is a valid substitute for the logical operator OR.
• Only one logical operator can be used to combine two relations. However, multiple relations can be combined into a complex logical expression.
• Regardless of the number of relations and logical operators used to build a logical expression, the result is either true, false, or indeterminate because of missing values.
• Operators or expressions cannot be implied.
