Write a program which copy one file contents to another. Your program should asked the file names from user.
#include <stdio.h>
int main()
{
char in_name[80], out_name[80];
FILE *in_file, *out_file;
int ch;
printf("Enter file name to be copied:\n");
scanf("%s", in_name);
printf("Enter output filename:\n");
scanf("%s", out_name);
in_file = fopen(in_name, "r");
if (in_file == NULL)
printf("Can't open %s for reading.\n", in_name);
else
{
out_file = fopen(out_name, "w");
if (out_file == NULL)
printf("Can't open %s for writing.\n", out_name);
else
{
while ((ch = fgetc(in_file)) != EOF)
{
fputc(ch, out_file);
}
printf("File has been copied.\n");
fclose(out_file);
}
fclose(in_file);
}
return 0;
}
