    Study Notes

    Bitwise Operations

    • The result of the bitwise OR operation between 12 and 25 is not specified.
    • The operator used for bitwise XOR in C Programming is ^.
    • The output of the bitwise XOR operation between 12 and 25 is not specified.

    Bitwise Complement

    • The result of applying the bitwise complement operator to the binary representation of 35 is -36.
    • The bitwise complement of 35 results in -220 in C Programming instead of 220 because of the signed integer representation.

    Constants in C Programming

    • Real or floating-point numbers are associated with floating constants.
    • Octal constants are represented in C programming with a leading 0 (zero).
    • A rule for representing a decimal integer in C programming is not specified.
    • 012 is NOT a valid decimal constant in C programming.
    • Hexadecimal constants are represented in C programming with a leading 0x or 0X.

    Characteristics of Constants

    • A characteristic of octal constants in C programming is that they start with a leading 0 (zero).

    Flowchart Symbols

    • The symbol used to denote any function of an I/O device in a program is a parallelogram.
    • The symbol used for calculations and initialization of memory locations in a flowchart is a rectangle.
    • From a decision symbol in a flowchart, there are two exits labeled as True and False.
    • The symbol used to connect a complex flowchart that spans multiple pages is an oval shape.

    Algorithm and System Development

    • In the algorithm provided, "Not divisible by 2" should be printed if a number is not divisible by 2.
    • In system development, feasibility study involves working with the existing system and using a proper questionnaire to explain the problem clearly.

    Typedef and Pointers in C Programming

    • The purpose of typedef in C programming is to assign alternative names to existing types.
    • In the first example provided, the size of the 'Age' structure is not specified.
    • The output of the first example's 'printf' statement: printf('Age.age : %d\n', Age.age) when Age.age = 7 is Age.age : 7.
    • Using typedef in C programming provides advantages such as increased code readability and portability.
    • When using typedef, the readability of the program improves.
    • The main application of typedef in C programming is to provide an alternative name for a type.
    • The purpose of pointer initialization in C programming is to assign the address of a variable to a pointer.
    • The symbol used as the address of operator in C programming is & (ampersand).
    • The indirection operator (*) in C programming is used to dereference a pointer.
    • The error that occurs in the statement 'float a; int *ptr; ptr = &a;' is a type mismatch (float to int).
    • The operator that gives the value from the address in C programming is * (indirection operator).
    • The role of reference operator (&) in C programming is to return the address of a variable.
