Respuesta :
The C library function fopen() is used to open a file for a variety of tasks, such as reading, writing, etc., as well as different modes. To copy the contents of the document into a text file, the C program reads the text file and then outputs as follows:
#include <stdio.h>
#include <stdlib.h> // For exit()
int main()
{
FILE *fptr1, *fptr2;
char fname[100], c;
printf("Enter the filename for reading \n");
scanf("%s", fname);
// Open one file for reading
fptr1 = fopen(fname, "r");
if (fptr1 == NULL)
{
printf("Cannot open file %s \n", fname);
exit(0);
}
printf("Enter the filename for writing \n");
scanf("%s", fname);
// Open another file for writing
fptr2 = fopen(fname, "w");
if (fptr2 == NULL)
{
printf("Cannot open file %s \n", filename);
exit(0);
}
// Read contents from the file
c = fgetc(fptr1);
while (c != EOF)
{
fputc(c, fptr2);
c = fgetc(fptr1);
}
printf("\nContents copied to %s", fname);
fclose(fptr1);
fclose(fptr2);
return 0;
}
