va_list with multiple types

i want to write soemthing like this:
a function which will print various types of arguments.
I tried to work with va_list, it doesn't work.
int main(){
write("this ",1.2," is ",'a',7," test");
}
should result in:
this 1.2 is a7 test

this isn't a multiple type function, your types are fixed.
"%s%.1f%s%c%d%s\n" specifies number&type of arguments.
Can you write it without "%s%.1f%s%c%d%s\n"?
