Here's a barebones program, the table won't work because i can't remember how to space correctly....and you might need to make some changes to the variable types (don't know if string will work w/ your compiler) but this should give yo uan idea.
String username;
String date;
Double Stock1name;
Double Stock1open;
Double Stock1close;
Double Stock1shares;
Double Stock2name;
Double Stock2open;
Double Stock2close;
Double Stock2shares;
Double Stock3name;
Double Stock3open;
Double Stock3close;
Double Stock3shares;
int main()
{
cout
cin>>username;
cout
cin>>date;
cout
cin>>stock1name;
cout
cin>>stock1open;
cout
cin>>stock1close;
cout
cin>>stock1shares;
cout
cin>>stock2name;
cout
cin>>stock2open;
cout
cin>>stock2close;
cout
cin>>stock2shares;
cout
cin>>stock3name;
cout
cin>>stock3open;
cout
cin>>stock3close;
cout
cin>>stock3shares;
cout
cout
cout
cout
return 0;
}
