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.




    C programming mainly consists of pre processor and functions, some data types as well as variables.
 Example---- :
Program is as follows,,,,


  #include<stdio.h>
  void main()
{
   int a=2;
   printf("%d",a);
}

 Output :2

     In that pre processor we use *include* this is command , which works the including to program. And also mainthing is header files , the header files consists of pre defined functions like printf ,scanf,pow,strrev..... Examples of header files are stdio.h, math.h,stdlib.h..........
   Examples-------:
   1. #include<stdio.h>
   2.#include<stdlib.h>
  3.#include<math.h>

In that function,we can write main function in that we use parameters or else we can leave that empty that is no parameters function. And also we can use return type integers or float or void. Void means we can't return anything. Default return type of any function is integer only.  If we declare as integer then we can return 0 or any value.
  Examples-----
    1. int main(a,b)
  Here a,b are parameters
 Int is return type of function
main is name of function
2.int main()
In this no parameters given, then is nothing problem in that.



Thank you for reading ..

I hope you understand , I follow up remaining topics next post....

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...
