Centering strings with printf()

Question

By default, printf() seems to align strings to the right.

printf(\"%10s %20s %20s\\n\", \"col1\", \"col2\", \"col3\");
/*       col1                     


        

Answer 1

You can use either of the following two options:

char name[] = "Name1";

//Option One
printf("%*s", 40+strlen(name)/2, name, 40-strlen(name)/2, "");
puts("");//skip one line

//Option two
printf("%*s", 40+strlen("Name2")/2, "Name2", 40-strlen("Name2")/2, "");

The output is:

Name1(center)
Name2(center)
