Write a program to create a heap file that holds the records in the file "data_2013"

The source records are variablelength.However, the heap file should hold fixed-length records. Create the new records accordingto the schema given in the below table.

2156_Write a program to create a heap file.png

All attributes with Unsigned Int type must be stored in binary, e.g. if the value of ID is equalto 70, it must be stored as 70 (in decimal) or 46 (in hexadecimal; in C: 0x46). It must not bestored as the string "70", occupying two bytes. Your heap file is therefore a binary file.For simplicity, the heap file does not need a header (containing things like the number ofrecords in the file or a free space list). The file should be packed, i.e. there is no gap between records.
