How can i have the output in double digits

[Lauramcm]

Hey... im new to c++ and im trying to write a program but am having difficulty trying to figure out how i can make my output have double digets even when it is 8 eg be 08.

i think its got somthing to do with a combination of setw, setfill and setprecision.

Please Help someone!

try

    int i=8;
    cout << setfill('0') << setw(2) << i << endl;

what about if it is for calculating time... say for instance


i get this...

3:4:24.2

but i need 03:04:24.2?

once you setfill() it is fixed until you change it, you have to use setw() before each variable to be printed.

speeds: 3.9 38.2 18.6

distances: 0.4 10 2.5


time: 00:06:09.2

time : 00:15:42.4

time : 00:08:03.9

Total time : 00:29:55.5

but i dont know how to get the last digets to be 09.2 or 03.9

try

    float x=9.2;
    cout << setfill('0') << setw(4) << x << endl;
