Data Types in C

In a portion of our instructional exercises to start with, I informed you concerning the three essential information types which are utilized in C language. Today I will acquaint you with certain varieties in these essential information types in C. We can make boundless information types according to our prerequisite in C. So C language is very wealthy in information types.

Information Types in C

The essential information types which we have utilized till now has a few cutoff points. For instance, we can just store esteems in the scope of – 32768 to 32767 for an int information type. Keep in mind this range is for 16 piece compiler Turbo C.

For 32 piece compiler like VC++, this range is – 2147483648 to +2147483647. You can’t store more qualities which surpass this utmost in int information type. To defeat those cutoff points we need to utilize some additional catchphrases like unsigned, marked and so on.

What are 16 piece and 32 piece compilers?

Turbo C is a 16 piece compiler. In the wake of changing over the C code into machine language, it will focus on that code to keep running on 16 piece processors like intel 8086.

Then again VC++ is a 32 piece compiler. It will focus to run the code on 32 piece processors like Intel Pentium processors.

short and long int

As I said before C language gives variety in its essential information types. short and long are such varieties of whole number information type. As its name recommends long has greater range than int.

Note: Here short and long are the two catchphrases.

The scope of both short and long are given underneath.

Scope of long is – 2147483648 to 2147483647.

Scope of short is – 32,768 to +32,767

marked and unsigned int

For the most part, it happened when we are affirmed that the worth won’t be negative regardless. So to use those conditions proficiently we frequently utilize unsigned int.

With the utilization of unsigned watchword the scope of int information type shifts from negative to positive.

The new range will be 0 to 65535

As a matter, of course, ordinary int is likewise called marked int.

marked and unsigned scorch

Scope of typical singe is – 128 to +127. You are more likely than not realized that burn information type consistently stores the ASCII estimation of character.

Commonly we rise in a condition when we have printed or access the ASCII character who worth is more than +127.

So, all things considered, we, for the most part, utilize unsigned scorch. Like int, it additionally makes the range twice. Both marked and unsigned roast involves 1 byte in memory.

The new range will be 0 to 255

buoy and twofold

skim variable involves 4 bytes in memory and it additionally gives a decent range to store esteems in it. It gives the scope of – 3.4e38 to +3.4e38.

In the event that you need to build this cutoff, at that point you can likewise utilize twofold information type.

It takes 8 bytes in the memory and it likewise gave an exceptionally huge range to store esteems. Its range is – 1.7e4932 to +1.7e4932.

The assertion of all information types

Given underneath are announcements of the considerable number of information types which we have adapted up until now.

int a;

unsigned int b;

long int c;

short int d;

unsigned short int e;

unsigned long int f;

scorch g;

unsigned scorch f;

drift g;

twofold h;


I Love python, so I like machine learning a Lot and on the other hand, I like building apps and fun games I post blogs on my website for Tech enthusiast to learn and Share Information With The World.
