[previous] 0179 [next] [U] Argument type does not match conversion specifier number %s.
Explicitly undefined REFERENCE - ISO:C90-7.9.6.1 Formatted input/output functions

This format string includes a conversion specifier which is not consistent with the type of the corresponding argument in a call to printf, fprintf or sprintf.

For example, in the code below, an argument (n) of type int is not consistent with the conversion specifier "%f". "%f" is only appropriate for data of type float.
