Last update on December 20 2024 13:16:31 (UTC/GMT +8 hours)

Write a program in C language to find the size of a given file.

Test Data:
Size of the said File: 34 bytes.

Sample Solution-1:

C Code:

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

long getFileSize(const char *filename)
{
  long result;
  FILE *fh = fopen("i.txt", "rb");
  fseek(fh, 0, SEEK_END);
  result = ftell(fh);
  fclose(fh);
  return result;
}
int main(void)
{
  printf("Size of the said File: %ld bytes.", getFileSize("input.txt"));
  return 0;
}

Sample Output:

Size of the said File: 34 bytes

{
  long result;
  FILE *fh = fopen("i.txt", "rb");
  fseek(fh, 0, SEEK_END);
  result = ftell(fh);
  fclose(fh);
  return result;
}
