/* Conformance Test 17.8.0.18: Verification of scanf, u format code */
#include <stdio.h>
Fix various C99+ conformance issues and bugs in test cases. The main changes made to most tests are: *Declarations always include explicit types, not relying on implicit int. The declaration of main in most test programs is changed to be "int main (void) {...}", adding an explicit return type and a prototype. (There are still some non-prototyped functions, though.) *Functions are always declared before use, either by including a header or by providing a declaration for the specific function. The latter approach is usually used for printf, to avoid requiring ORCA/C to process stdio.h when compiling every test case (which might make test runs noticeably slower). *Make all return statements in non-void functions (e.g. main) return a value. *Avoid some instances of undefined behavior and type errors in printf and scanf calls. Several miscellaneous bugs are also fixed. There are still a couple test cases that intentionally rely on the C89 behavior, to ensure it still works.
