您将 seconds 声明为整数，因此您应该更改%.5f为%d.

#include <stdio.h>
void main (void)
{
  int days, seconds;

  printf("Enter the no. of days: ");
  scanf("%d", &days);
  
  seconds = days*36400;
 
  if (days<0)
    {
      printf("Invalid input!");
    }
  else 
    {
      printf("It is equal to %d seconds", seconds);
    }
  
}
