[Furiwel]

Hello everbody:
Im having problems with this little thing in a C example Im doing.
I want to show in the shell like this example:

Im trying to use the printf function but the names doesnt have the same lenght, so any idea?
So I cant do it like this:
printf("Name Bithday\n");
printf("%s %d\n");

Hello,
You can use simple code to execute in shell :


printf "Name\t Birthday\n"
printf "XYZ\t 12-12-2010\n"

Hello vmandale

the thing is that if I put it like that it doesnt make right, because the names havent got the same length. Maybe using some options from the shell?

When using printf, you actually can specify the length of your data:

printf("%6s %2d\n", name, birthday);

This will force the name to be six characters, and the birthday to be 2 characters. Spaces will be added to the left of the output if it is not long enough.

Note that if any of your data is longer than 6 characters, this will not work (it will not shrink output). Therefore, you will want to use the longest width that you have to.
