You are not allowed to define functions inside other functions.
Move the function inside the switch statements outside of main and just call the functions from main.

"hard time" is an inaccurate description of the problem.
The compiler lists errors and warnings. It is useful to read and understand them.

For example, I did pull the addRecord() outside, as Thomas suggested.
The compiler sees these issues in it:
warning: unused parameter 'size' [-Wunused-parameter]
error: 'i' was not declared in this scope
error: 'count' was not declared in this scope

void addRecord (struct StockInfo portfolio,int size) // warn
{
  cout << "enter company's  name please:"<<endl;
  cin>>portfolio[i].coname; // error
  // more of those
  count++ // error
}

The compiler got a bit confused though; it does not mention that there is no ; after the count++


Two notes:
1. Your indentation is not systematic. That affects readability.

2. C++ does not require struct when you do use typename:

void addRecord( struct StockInfo, int );
void addRecord( StockInfo, int ); // sufficient
