As we learned in the previous post, C# supports a type system. Part of that system is a group of "basic" types. These types, also called primitive types, form the foundation of many C# programs.
The most basic of the primitive types are the number types. These include integral numeric types (which represent whole numbers, like 1, 67, 1957321, 8, and so on) and _floating-point numeric types _(which represent non-whole numbers such as 1.2, 6.99, 8234.66, and so on).
Of the integral numeric types, the type
int is the default and most common.
int represents a 32-bit integer, with a positive or negative value.
int five = 5; int thirteenHundred = 1300; int negativeForty = -40; int intMaxValue = int.MaxValue; //(2^32 - 1)
int is used for many kinds of variables, including math, counters, and iterators.
byte are all integral numeric types, like
int. However, they represent different ranges of values.
short represents a 16-bit integer:
short three = 3; short negativeOneHundred = -100; short shortMaxValue = short.MaxValue; //(2^16 - 1)
long represents a 64-bit integer:
long fifty = 50; long longMaxValue = long.MaxValue; //(2^64 - 1)
byte is a 8-bit integer that only represents positive values.
byte four = 4; byte byteMaxValue = byte.MaxValue; //(2^8 - 1)
C/C++ problems. If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends.
In this Video We are going to see how to use Loops in C++. We will see How to use For, While, and Do While Loops in C++.
In this article, we'll take a look at using the isdigit() function in C/C++. This is a very simple way to check if any value is a digit or not. Let's look
C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.
In this article, we’ll take a look at using fread() in C/C++.
