Program Plan Intro
Logical “&&” Operator:
Logical operator combines the results of one or more conditions.
- The logical “&&” is used to evaluate two expressions in order to obtain a single relational result.
- It returns the Boolean value “True” when both the operands are true, otherwise returns “False”.
- The first operand is evaluated first and all the side effects are completed before evaluating the logical “and” expression.
- The second operand is evaluated only if the first operand is “True”.
Syntax for “&&” operator:
The syntax for “&&” operator is given below:
expression1 && expression2
Logical “||” Operator:
Logical operator combines the results of one or more conditions.
- The logical “||” is used to evaluate two expressions in order to obtain a single relational result.
- It returns the Boolean value “True” when one of the operands is “True”. It returns “False” only if both the operands are “False”.
- The first operand is evaluated and all the effects are completed before it continues to evaluate the logical “||” expression.
- The second operand is evaluated only if the first operands return “False”.
Syntax for “||” operator:
The syntax for “||” operator is given below:
Expression1 || expression2
Logical “!” Operator:
Logical NOT operator one conditions.
- The logical “!” is used to evaluate one expressions in order to obtain a single relational result.
- It returns the Boolean value “True”. If the operand is “False”.
- It returns the Boolean value “False”. If the operand is “True”.
Syntax for “!” operator:
The syntax for “!” operator is given below:
!Expression2

An ISBN (International Standard Book Number) is a 10 digit number that is used to identify a book. The first nine digits of the ISBN number are used to represent the Title, Publisher and Group of the book and the last digit is used for
checking whether ISBN is correct or not. To uniquely identify a book a 10-digit ISBN number is used. The rightmost digit is checksum digit. This digit is determined from the other 9 digits using condition that 10d, + 9dz + 8dg + + d4o
must be a multiple of 11 (where d, denotes the i" digit from the right). The checksum digit d; can be any value from 0 to 10: the ISBN convention is to use the value X to denote 10. Write a C program using pointers that receives a 10-
digit ISBN, and computes the checksum, and reports whether the ISBN number is correct or not.
Example: 007462542X = 10°0 + 9*0 + 8*7 + 74 + 6*6 + 5*2 + 4*5 + 3"4 + 2*2 + 110 = 176
Since 176 leaves no remainder when divided by 11, hence it is a valid ISBN.
Note: When the check digit turns out…
Assignment details:
Replace all the 0 (Zero) digits in your ID by 4.
Example: If your ID is 38104680, it becomes 38144684
Take the first 6 digits and substitute them in this expression (( A + B) / C) * ((D-E)/F)-2) according to the following table;
