Can you put the actual/expected results in [output][/output] tags?
Otherwise multiple spaces are lost in your post and we can't know what is the result you want

[autorobot14]

this my output

Item Price
Television............RM 2398
DVD Player............RM 250
Biscuits..............RM 31.5
*******************************

cout<<setw(22)<<setfill(' ')<<left<<"Item"<<""<<setw(9)<<setfill(' ')<<right<<"Price"<<endl;
cout<<setw(22)<<setfill('.')<<left<<"Television"<<"RM"<<setw(7)<<setfill(' ')<<setprecision(2)<<fixed<<right<<tv<<""<<endl;
cout<<setw(22)<<setfill('.')<<left<<"DVD Player"<<"RM"<<setw(7)<<setfill(' ')<<right<<dvd<<""<<endl;

setprecision and fixed manipulator change the output for floating point numbers.

Thank..it work :)

[autorobot14]

emm just want to asking. How about showpoint

[Bazzy]

You'll notice the difference only if you don't use fixed and setprecision(n) with n>=1

1 2 3 4

cout << showpoint << 123. << endl; cout << noshowpoint << 123. << endl; cout << fixed << setprecision(2) << showpoint << 123. << endl; cout << noshowpoint << 123. << endl;

123.000 123 123.00 123.00
