Implicit and Explicit type conversion | C Language
Implicit and Explicit type conversion | C Language
Implicit Typecasting
Implicit type casting means conversion of data types without
losing its original meaning. This type of typecasting is essential when you
want to change data types without changing the significance of the values
stored inside the variable.

Advantage of Pointer | C Language
Advantage of Pointer
- It provides dynamic programming environment.
- Physical location of memory can be direct access through pointer.
- It allow to call by reference to function which help to achieved many dynamic operation.
- Dynamic memory allocation is achieved through array.
- Fire read write operations are achieved through pointer.
- Management of structures which are allocated memory dynamically is efficiently achieved by pointer.

File read write function | C Language
1. ftell()
Returns the current file pointer position in numeric form.
Declaration:
long ftell(FILE *stream);
Remarks:
ftell
returns the current file pointer for stream.If the file is binary, the offset is
measured in bytes from the beginning of
the
file The value returned by ftell can be used in a subsequent call to fseek.
Return Value:
On success, returns the current file pointer
position.
On error, returns -1L and sets errno to a
positive value.
Example
#include <stdio.h>
int main(void)
{
FILE *stream;
stream = fopen("MYFILE.TXT",
"w+");
fprintf(stream, "This is a test");
printf("The
file pointer is at byte %ld\n",
ftell(stream));
fclose(stream);
return 0;
}
2. rewind()
Repositions
file pointer to stream's beginning
Syntax:
void rewind(FILE *stream);
Remarks:
rewind(stream) is equivalent to fseek(stream, 0L, SEEK_SET)
except
that rewind clears the end-of-file and error indicators, while fseek
only clears the end-of-file indicator.
After
rewind, the next operation on an update file can be either input or
output.
#include <stdio.h>
#include <dir.h>
int main(void)
{
FILE *fp;
char *fname = "TXXXXXX", *newname, first;
newname = mktemp(fname);
fp = fopen(newname,"w+");
fprintf(fp,"abcdefghijklmnopqrstuvwxyz");
rewind(fp);
fscanf(fp,"%c",&first);
printf("The
first character is: %c\n",first);
fclose(fp);
remove(newname);
return 0;
}

Array an introduction | C Language
Array
An array is a collection of similar data type which occupies
continuous location on memory. Array is useful bulk process is required on
similar data type. Name of array is a constant pointer which point first
element of array. Elements of array are access through index number. Index
donates numeric position of data in an array. Index start with zero and last
element less than one from the specified size of array.
Syntaxt :
Data_type arr_name[size_int]
