Data types in c

-
Welcome to c programming

After the function in c programming we have to use curly braces. In that braces we can write statement what ever we want to do.  And next , we have to mind one thing that is  every statement must ends with semicolon (;).

    Example------
          int i;
 Here it is data type and this whole thing is statement

In that printf and scanf are the input and output function, which are returning integer values only, these two are predefined functions.



And also main part to learn in c programming is data types that is  as follows....
1.int
2.float
3.double
4.char


1.int:--
    int is one the data type in c programming those are indication of integer values only.
In that int we have signed integer and unsigned integer. These two integer data type difference making at ranges. In unsigned we don't have negative ranges that means starts from zero. In this long int and short two types are there in the integers.

Examples------ int i;
            int i=5;
2. Float: -----
These is used for the float values which are having pricision of 6 digits.

 Example----
 1.float t;
2.float t=5.0000;
3.float  r=5.6;

3.double:---
This is another one for float values but the difference is how many digits after point or decimal values. In this precision value is 15 digits
Example------
    A.double a;
   B.double b=6.89999926762;



4.char::::
Char is used to represent a character and in c programming language we don't have string data type that's why we use char array as string. In this signed and unsigned char is there for address only. This is starts  from -128 to  +127. This is 1 byte address data type.




In this way we have data types , which are predefined data types. We have some user defined data types , those are struct......

strings in c programming

coming to strings in c programming.... string is a character of array. that in this we can represent characters. for example char s[20] means that we can write a word of character up to 19 characters. strings data also starts from zero index on wards but the difference is to find some operations we have predefined functions like strlen(), strcpy()...etc string can be consist of special characters. in fact in c programming there is no such data type to indicate strings directly... for example one program to find length of the string .... #include<stdio.h> void main() { char s[10]; scanf("%c",&s); int n=0; n=strlen(s); printf("%d",n); }

Header files in c

Welcome to c programming learning Last post program output is 2 Now we are going to learn about header files. HEADER FILES Header files are very important in c programming language because these header files consists of predefined functions like printf(),scanf(),pow()....etc There we have more header files in that we learn here some which are some what important... 1.stdio.h In this header file consists of address of Function that is printf() and scanf() functions addresses. This means standard input and output. 2.conio.h Next of above header file we use this. In this we have two main functions definition those are clrscr(), getch(),getche() 3.stdlib.h  This is standard library header file. In this we have dynamic memory allocation functions definition ,those are malloc,calloc,realloc,free. And also delay(),rand(),abs(),exit() functions definition are there in this library. 4.math.h This header file consists of all mathematical functions defin...

C programming  It is really very easy to learn so move forward..... C programming is a basic programming language, which is procedure oriented language that means this c language is all works on functions only like main function and other predefined or user-defined functions.
