Which STL class is the best fit for implementing a phonebook in C?

What is the smallest size a variable of the type Child_t may occupy in memory?

This means that an object of type child_t_packed will occupy exactly one byte in memory.

What is the difference between a public and a private class member Linkedin?

Public members can be accessed by any function. Private members can be accessed only by the same class’s member functions and the friends of the class.

Which choice is not a difference between a class and a struct Linkedin?

Which of the following is not a difference between a class and a struct? Because structs are part of the C programming language, there are some complexity between C and C++ structs. This is not the case with classes. Classes may have member functions; structs are private.

What is the storage occupied by u1?

union { unit16_t a; unit32_t b; int8_t c; } u1; 4 bytes.

What are the important points to be considered when implementing bit fields in structures?

What are the important points to be considered when implementing bit-fields in structures? 1)Bit fields result in non-portable code. Also, the bit field length has a high dependency on word size. 2)Using scanf() function…

What is size of structure in C?

The size of the entire structure is 8 bytes. On knowing the structured padding, it is easier to redesign or rewrite the structure.

Which type of class Cannot be created?

Explanation: Instance of abstract class can’t be created as it will not have any constructor of its own, hence while creating an instance of class, it can’t initialize the object members. Actually the class inheriting the abstract class can have its instance because it will have implementation of all members.

What qualities must a class possess?

Class Quality

• Coupling.
• Cohesion.
• Sufficiency.
• Completeness.
• Primitiveness.

What quality must a class possess OOP?

The object can be accessed, declared, and used locally in that function. The object must be declared inside any other function. The object is temporarily accessible outside the function. The object can call all the other class members anywhere in the program.

What is one difference between a struct and a union?

Structures are used to represent a record. A union is a special data type available in C that allows storing different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time.

What is the difference between parameter and argument?

Note the difference between parameters and arguments: Function parameters are the names listed in the function’s definition. Function arguments are the real values passed to the function. Parameters are initialized to the values of the arguments supplied.

What is an appropriate way of removing My_object as shown below?

What is an appropriate way of removing my_object as shown below? my_class *my_object = new my_class(); delete(my_object); free(my_object);

What is the size of union in C?

When we declare a union, memory allocated for a union variable of the type is equal to memory needed for the largest member of it, and all members share this same memory space. In above example, “char arr[8]” is the largest member. Therefore size of union test is 8 bytes.

What is union memory?

Advertisements. A union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose …

What are different types of files in C?

C programming language supports two types of files and they are as follows…

• Text Files (or) ASCII Files.
• Binary Files.
