File Handling In C

Hello Friends,

File Handing in C language is one of the most important topic. The program which written below will make one file and you can write your data as you wanted.

Example:

#include<conio.h>
#include<stdio.h>

void main()
{
      FILE *f1;                    // File pointer variable declared
      char c;

      printf("Enter Data\n\n");

      f1=fopen("DATA","w");  // File DATA created and ready to write

     while((c=getchar()) != EOF)
     {
             
                 putc(c,f1);

     }
     fclose(f1);
     printf("\n\nYour Data in File:\n\n");

    f1=fopen("DATA","r")                // File will open in read mode

    while((c=getc(f1)) !=EOF)
   {
            printf("%c",c);
   }

 fclose(f1);

getch();

}
