File handling Index 1.     Introduction 2.     File Operations 3.     Input Operations on File 4.     Output Operations on File 5.     Error handling 6.     Random access to Files 1.     Introduction             In Computer, when we run programs, they use memory (RAM) to store the variables, which are temporary. Memory is volatile and its content will be in memory till the program is running, once the program get terminated, then values stored in parameter also erased. If we need data again then we need to use keyboard input. So this will be valid for small data, but for large data it’s not possible to enter data again and again when you require it and another way to get the values may be generate the values pragmatically. But both of the ways are very difficult to implement.        ...
