What is bit field in c?
A bit field in C is a way to allocate a specific number of bits for variables within a structure. This allows for efficient storage of data by using only the necessary number of bits, which is particularly useful in situations where memory conservation is crucial, such as embedded systems or hardware interfacing. Bit fields are defined using the syntax type name : width, where type is typically an integral type, name is the identifier, and width is the number of bits allocated to that field. However, the use of bit fields can lead to portability issues due to differences in how compilers handle alignment and ordering of bits.
Why bit masking is required in c language?
Bit masking is required whenever we need to invert a group of bits in a bit field. Bit masks allow us to perform these changes in a single operation rather than one bit at a time.
Is bit stuffing needed for the control field as in case of address data and FCS fields of the HDLC frame?
Yes, bit stuffing is needed for the control field in HDLC frames, similar to the address and Frame Check Sequence (FCS) fields. Bit stuffing is used to prevent the occurrence of specific bit patterns, such as the frame delimiter (0x7E), within the data fields, including the control field. By inserting a '0' after a sequence of five consecutive '1's, bit stuffing ensures that the frame remains distinguishable and can be correctly framed during transmission and reception.
Difference between class and structure in csharp?
I'm not sure about csharp, but in OO a class has a state and behaviour whereas structure has only state.The state of a class is the data members, or attributes of a class. Behaviour of a class is the function members, or the methods of a class. Ie, a class has attributes and functions, but a struct has only attributes.Historically, classes derived from structures. At one point someone thought of adding behaviour or functionality to structures and the resulting type was called a class.I'll give you an example.struct Student {//stateint YearInCollege;};This structure has only data members that can be manipulated in the program. Eg:Student You;You.YearInCollege=1; //change state...int a=You.YearInCollege; //read stateAs you can see, we can read and write the members of a structure as we wish.Now, let's give the structure a bit of functionality.class Student {//behaviourint WhatsMyYearInCollege(void);void ChangeMyYearInCollege(int);//stateint YearInCollege;};as you can see, now besides the state we also have functionality to change the state of the class. Now, we'll change the state of the class only through its own member functions, also called mutator functions. Eg:Student You;You.ChangeMyYearInCollege(2); //change state through class' own function...int a=You.WhatsMyYearInCollege(); //read state through class' own function
Is it possible to change the data type for a field that already contains data?
You can change the data type of an existing field using a union, however, you should understand that bit format dependance is not portable usage, and that you should initialize the field every time you change your desired type.Answer: without specifying the context, this question cannot be answered.
What are bit fields What is the use of bit fields in a Structure declaration?
Both C and C++ allow integer members to be stored into memory spaces smaller than the compiler would ordinarily allow. These space-saving structure members are called bit fields, and their width in bits can be explicitly declared. Gagandeep Singh Bitfields can only be declared inside a structure or a union, and allow you to specify some very small objects of a given number of bits in length. struct { /* field 4 bits wide */ unsigned field1 :4; /* * unnamed 3 bit field * unnamed fields allow for padding */ unsigned :3; /* * one-bit field * can only be 0 or -1 in two's complement! */ signed field2 :1; /* align next field on a storage unit */ unsigned :0; unsigned field3 :6; }full_of_fields; The main use of bitfields is either to allow tight packing of data or to be able to specify the fields within some externally produced data files.

What is define real number?
It is a bit hard to define them - and the exact definitions are a bit formal. It is best to think of real numbers as the equivalent of all points on a straight line, infinite in both directions.

Define bit in microprocessor?
: A Bit is a digit in the binary number system. It can have two values, 0 or 1. In computer RAM and ROM memory, a bit is a small electrical switch which is either on (value 1) or off (value 0).
Similarities between union structure enum in c?
Structures and unions share the following characteristics: * Their members can be objects of any type, including other structures and unions or arrays. A member can also consist of a bit field. * The only operators valid for use with entire structures and unions are the simple assignment (=) and sizeof operators. In particular, structures and unions cannot appear as operands of the equality ( == ), inequality (!=), or cast operators. The two structures or unions in the assignment must have the same members and member types. * A structure or a union can be passed by value to functions and returned by value by functions. The argument must have the same type as the function parameter. A structure or union is passed by value just like a scalar variable; that is, the entire structure or union is copied into the corresponding parameter. similarity is all three are user defined data types.
Which is sronger shell structure or solid structure?
