The struct default access type is public. A struct shouldtypically be used for grouping data.
The class default access type is private, and the default mode for inheritance is private. A class should be used for grouping data and methods that operate on that data.
In short, the convention is to use struct when the purpose is to group data, and use classes when we require data abstraction and, perhaps inheritance.
In C++ structures and classes are passed by value, unless explicitly de-referenced. In other languages classes and structures may have distinct semantics - ie. objects (instances of classes) may be passed by reference and structures may be passed by value.
Technically there are only two differences between classes and structures:
Most C++ programmers use structures exclusively for data that doesn't require strict validation while classes are used to encapsulate data and the functions that work exclusively with that data. Although classes and structures can largely achieve the same goals, the lack of encapsulation and data-hiding in a structure make it far less robust than a well-designed class would be, with little or no difference in terms of memory consumption. Encapsulation comes into its own when classes become highly-complex (classes within classes) as each class is responsible only for its own data, not the classes it contains. Structures can be just as complex, but because they don't have the safeguards that can built into classes, it only takes one errant function to unwittingly invalidate data. A well-designed class ensures data validity at all times.
Depends on the computer language, but in general, a structure is a value-type, while an instance of a class is a reference-type. A structure or struct, may not offer inheritance, classdoes.
At the simplest level, a structure is a class where the default access specifier is public, instead of private.
Formally, a structure is a class that has no methods, be they constructor, destructor, or otherwise, nor access specifiers. I make this distinction because some C++ compilers do not differentiate, and will allow you to create them, but structures with methods or access specifiers are outside the language definition.
Structures are public by default. Classes are private. Other than that, they are essentially the same in C++.
difference between serch data structure and allocation data structure
The difference between the Class 365 and Class 465, 466 is basically the cost.
class III rated for up to 5,000lbs, class IV is rated for up to 10,000lbs towing capacity
The structure tag is a type. The structure variable is an instance of that type.
The main difference is the thickness of the pipe Compare to A Class pipe B Class pipe thickness is more.Like that Compare to B class pipe C Class pipe thickness is more.
structure variable can access the variable but class object can access the function also

There does not have to be a difference between a tall organization structure and a flat organization structure. These structures can be the same structure.
the difference between phrase structure and ica
By default, all of the members of a class are private and, by default, all of the members of a structure are public.Structure are value type where as class are reference type.'this' pointer will work only in class.Inheritance between classes is also private by default, and inheritance between structs is public by default.Classes support polymorphism, whereas structure do not.
the difference between an organisational structure and a matrix structure is that a matrix structure is a combined structure whereas an organisational structure is in a vertical order and has different levels.
difference between formal organization structure and informal organization structure.
The difference between the Class 365 and Class 465, 466 is basically the cost.
difference between inclusive and exclusive class interval
All buildings are structures but not all structures are buildings
What is the difference between buying a 1st class and a 2nd class ticket on the train in England?
the difference is ,a structure is where it is placed and the function is what it daos
