Question

Write aprogram that inputs the employee records from the user and saves itto a file called employee.dat. The program opens the file again,reads all the records from the file employee.dat, stores them intoa one-dimensional array, and then displays the contents of allrecords. Create a structure to store the employeerecord.

structEmployee
{ char nam[80];
   double salary;
};

Output sample

Entername:
aa
Enter salary:
45.8
Do you want to enter another record?y
Enter name:
bb
Enter salary:
23.6
Do you want to enter another record?y
Enter name:
cc
Enter salary:
90.5
Do you want to enter another record?y
Enter name:
dd
Enter salary:
100.35
Do you want to enter another record?n

EMPLOYEE RECORDS:
aa
45.8
bb
23.6
cc
90.5
dd
100.35
