Show us something that acutally compiles. We have no indication where the
code snippet above the function declaration takes place. In mane? In a
constructor? In an initializer? Never?
Since you're getting an error when dereferencing the pointer, I'm guessing
never.

I could not even compile it:
sss.cpp:1: error: expected constructor, destructor, or type conversion
before '=' token
sss.cpp:2: error: expected constructor, destructor, or type conversion
before '=' token
sss.cpp:3: error: expected constructor, destructor, or type conversion
before '<' token
sss.cpp:4: error: expected unqualified-id before 'for'
sss.cpp:4: error: expected constructor, destructor, or type conversion
before '!=' token
sss.cpp:4: error: expected constructor, destructor, or type conversion
before '++' token
sss.cpp:10: error: 'doba' has not been declared
sss.cpp: In function 'int vrat_pocty_hodin_prace()':
sss.cpp:11: error: 'pocet_prac' was not declared in this scope
