Write a program to merge two files into the third file.
#include<stdio.h>
void Merge_two_files(FILE*,FILE*,FILE*);
int main()
{
char first[32],second[32];
FILE *f1,*f2,*f3;
printf("Enter first file name = ");
scanf("%[^\n]",first);
printf("Enter second file name = ");
scanf(" %[^\n]",second);
f1 = fopen(first,"r");
f2 = fopen(second,"r");
if(f1 == NULL || f2 == NULL)
{
printf("file is not present in present working directory\n");
return 0;
}
Merge_two_files(f1,f2,f3);
return 0;
}
void Merge_two_files(FILE *p1,FILE *p2,FILE *p3)
{
char ch;
p3 = fopen("result","w");
while((ch = fgetc(p1)) != EOF)
{
fputc(ch,p3);
}
while((ch = fgetc(p2)) != EOF)
{
fputc(ch,p3);
}
fclose(p1);
fclose(p2);
fclose(p3);
}
Output
Enter first file name = d1 Enter second file name = d2
