C Program to Copy Text From One File to Other File

Program : Copy Text From One File to Other File

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

void main()
{
   FILE *fp1,*fp2;
   char ch;
   clrscr();

    fp1 =  fopen("Sample.txt","r");
    fp2 =  fopen("Output.txt","w");

    while(1)
    {
       ch = fgetc(fp1);

       if(ch==EOF)
          break;
       else
          putc(ch,fp2);
    }

    printf("File copied succesfully!");
    fclose(fp1);
    fclose(fp2);
}

Explanation :  To copy a text from one file to another we have to follow following Steps :
Step 1 : Open Source File in Read Mode

fp1 =  fopen("Sample.txt","r");

Step 2 : Open Target File in Write Mode

fp2 =  fopen("Output.txt","w");

Step 3 : Read Source File Character by Character

while(1)
    {
       ch = fgetc(fp1);

       if(ch==EOF)
          break;
       else
          putc(ch,fp2);
    }

• “fgetc” will read character from source file.
• Check whether character is “End Character of File” or not , if yes then Terminate Loop
• “putc” will write Single Character on File Pointed by “fp2″ pointer

Input Text File :

Output Written on File
