Difference Between C# and C++ :-
Most of the C# features are similar to those of C++. However, C# provides various additional features that make it a more type –safe and web enabled language. Various points of different between C# and C++ are :
Classes in C# are defined are implemented at the same place and so there is no need for using header files.
C# does not use header files as it compiles directly from the source code to the executable code.
C# does not use semicolon at the end of class definition.
C# does not support pointers for manipulating data. However, they are used in codes declared as unsafe.
C# does not contain any default constructor.
Behaviour of the command line arguments is different in C# as compared to C++.
Abstract of C# cannot be implemented.
C# does not support macros.
Objects in C# can only be created using new keywords.
C# allows the switch statement to be used with string values.
C# does not support multiple inheritance.
Declaration of array is different in C# as compared to C++. Arrays in C# are of reference type while in C++ arrays are of value type.
C# does not support the header file,# include.
All the data types in C# are inherited from the object super class and therefore they are objects.
In C#, structs are of value type.
C# does not support the typed of statement.
C# supports native Boolean type and Boolean type data can be implicitly or explicitly cast to any data type except object.
C# does not support default arguments.
Difference Between C# And Java :-
C# and java are both used in web based programming. C#
Contains various features similar to java. However it contains various features different of java,
C# contains more primitive data types than java.
C# supports operator overloading while java does not supports operator overloading.
C# supports the strut type while java does not support.
AII data types in C# are strut.
C# provides more data types as compared to java.
C# provides better versioning than java.
C# allows parameters to be passed by reference by using the ref keyword where as java allows parameters to be passed by value.
C# allows variable number of parameters using the param keyword.
C# provides static constructors for initialization.
C# does not provide the break statement. The goto statement is used to achieve this.
Declaration of arrays is different in C# as compared to java.
The convention for java is to put one public class in each file and in fact, some compilers require this. C# allows any source file arrangement.
