1:
Code:
cout << setiosflags(ios::fixed)<<1000000000000.0 << endl;
if we skip setiosflags(ios::fixed) what will it happen
2: does
means
Code:
ValueSum=ValueSum+Value
3:[/code]void PrintChar(char c = '=', int n = 80)[/code]
if we call the above function from main with these 4 options what will happen
Code:
PrintChar('*', 20); PrintChar('-'); PrintChar(); PrintChar(20);
4: whats the different when we externally declare variables and how can we change them from different locations
5: i cannot understand about the new option i think it somehow bind memory blocks? is it an array or something? when do we have to unbind it? if we dont what will it happen
6: im unable to understand what substr is and how can we use it, also i cannot understand what getline() is
thanks in advance
