If you have been express to c, or if you are an experienced cprogrammer, you might be interested in the main differences BetWeen C # and C: C: C: C: C: C: C # and C is:

1. C # does not usually make use of pointers, or Decrement a variable as if it were an actual memory pointer Inside a special unsafe block.c # does not use pointers frequently. You can only do an Increment and Decrement operations as an actual memory pointer in a special non-type secure code segment. 2. You can Declare Variables Anywhere Inside a Method You Want To; The beginning of the method. You can declare variables in any location in the method, not necessarily in the start of the function, 3 . You don't have to declare an Object Before You Use; you can define it just as you need it. You don't have to declare an object first before use, then declare it when you use 4. C # HAS A Somewhat Different Definition Of the struct type, and does not support The Idea of ​​a union at all.c # There are some differences in the definition of the structure, but the joint data type 5. C # HAS Enumerated Types, Which Allow A Series of named VALUES, Such As Colors or Day Names, To Be Assigned Sequential NumBers, But The Syntax Is Rather Different.c # There are enumeration data types, you can store known data types, such as Color or Day, but syntax is quite different 6. C # does Not Have Bitfields: Variables That Take Up Less Than A Byte of Storage. C No bitfields (Variable occupies less than 1 byte of data type) 7. C # does not allows Variable length Argument Lists. You Have to Define a Method for Each Number and TYPE OF ARGUMENT. HOWEVER C # Allows for the Last Argument of a Function To Be a variable parameter Array.c # does not support the length of the variable byte length, you can only define a function similar to SIZEOF for each method or data type, but C # Allow the last one of the function The parameter is array parameters.
