[Error]C:\User\HP\Documents\C-Free\Temp\Untitles3.cpp:54: error: no match for 'operator[]' in 'emp[i]'
[Error]C:\User\HP\Documents\C-Free\Temp\Untitles3.cpp:55: error: no match for 'operator[]' in 'emp[i]'

emp is a single object. Why are you trying to use the [] operator with it, as if it were an array?

[booradley60]

The variable emp[i] doesn't mean anything because emp is a single employee, given the declaration: employee emp;

What you want is a collection of employees. Do you know how to use arrays or vectors?

[anuasya]

so if i decrale it as
employee emp[10];
Is it gonna work???

[MikeyBoy]

That will work, as long as the user doesn't enter more than 10 for the number of employees.

Ty... :)
It is working now
Actually I dint notice tht i had declared it as a variable.. :P Wht I wanted was an array
