C language

C language high level course contents:

1. keywords, operators, control statements, functions, recursion

   • keywords (23): int, char, float, double, void, return, short, long, signed, unsigned, sizeof, const, if, else, switch, case, default, for, while, do, break, continue, goto

   • operators (30): + - * / % < <= > >= == != && || ! & ^ | ~ << >> = + - ++ -- (type) , () ?: sizeof

2. arrays, pointers, strings, enumerations, structures, unions

   • keywords (4): enum, struct, union, typedef

   • operators (4): [] * . ->

3. storage class specifiers, type qualifiers, preprocessor directives

   • keywords (5): auto, register, static, extern, volatile

   • operators (0): NIL

software

    functions

      statements - declaration, expression, function call, return, etc

           expression - operands (keywords) + operators

• basic constructs of C program - expression, statement, block, function, I/O functions, header files.

• keywords - datatypes

• operators - precedence & associativity

• control statements

• functions & recursion

Basic data types: char, int, float, double

derived data types: arrays, pointers, strings

user defined data types: enumerations, structures, unions

34 operators:

+ - * / %

< <= > >= == !=

&& || !

& | ^ ~ << >>

=

?:

+ - ++ -- (type) sizeof , ()

[] * . -> 

Assignments:

1. library functions ==> ch19

2. digital gates ==> AND, OR, NOT, NAND, NOR, XOR, XNOR ==> truth tables, symbols, conversion (done)

3. number systems ==> binary(2), octal(8), decimal(10), hexa-decimal(16) / BCD (binary coded decimal)==> conversions (done)

4. Read about operators: 11 (done)

& | ^ ~ << >>

?:

++ -- (type) ,

5. study keywords goto. done

6. study nesting of loops. done

7. what is recursion? done

8. write a c program to find x power y. done

9. write a c program to find if a given number is prime number. done

10. write a c program to find a factorial of a given number. done

11. write a c program to find sum of the digits of a number.

a=45732;  ==> 4+5+7+3+2 ==> 21

a=1234567; ==> 1+2+3+4+5+6+7 ==> 28

12. write a c program to find multiplication of the digits of a number.

a=45732;  ==> 4*5*7*3*2 ==> 840

a=1234567; ==> 1*2*3*4*5*6*7 ==> 5040

13. write a c program to reverse a number.

a=45732; ==> 23754

a=1234567; ==> 7654321

14. write a c program to check given number is palindrome or not

a=45732; ==> 23754 ==> not a palindrome

a=12321; ==> 12321 ==> palindrome

a=131; ==> 131 ==> palindrome

a= 1356531; ==> 1356531 ==> palindrome
