Program to merge
the contents of two files
Program:
#include<stdio.h>
#include<conio.h>
void main()
{
char c;
FILE *fptr1, *fptr2, *fptr3;
clrscr();
printf("Enter the text to be stored in the file - 1.\n");
printf("Use ^Z or F6 at the end of the text and press ENTER : \n\n");
fptr1 = fopen("FIRST.DAT","w");
while((c = getc(stdin)) != EOF)
fputc(c, fptr1);
fclose(fptr1);
printf("\nEnter the text to be stored in the file - 2.\n");
printf("Use ^Z or F6 at the end of the text and press
ENTER : \n\n");
fptr2 = fopen("SECOND.DAT","w");
while((c = getc(stdin)) != EOF)
fputc(c, fptr2);
fclose(fptr2);
fptr1 = fopen("FIRST.DAT","r");
fptr2 = fopen("SECOND.DAT","r");
fptr3 = fopen("MERGE.DAT","w");
while((c = fgetc(fptr1)) != EOF)
fputc(c, fptr3);
fclose(fptr1);
while((c = fgetc(fptr2)) != EOF)
fputc(c, fptr3);
fclose(fptr2);
fclose(fptr3);
printf("\nThe content of the merged file is : \n\n");
fptr3 = fopen("MERGE.DAT", "r");
while((c = fgetc(fptr1)) != EOF)
putchar(c);
fclose(fptr3);
getch();
}
Output:
Enter the text to be stored in the file - 1.
Use ^Z or F6 at the end of the text and press ENTER :
Computer Practice - I
I - Semester
^Z
Enter the text to be stored in the file - 2.
Use ^Z or F6 at the end of the text and press ENTER :
Computer Practice - II
II - Semester
