程序的结果是什么

.code.tio.c:13:3: error: use of undeclared identifier 'r' } r ^ .code.tio.c:15:3: error: unknown type name 'in' } in ^ .code.tio.c:16:2: error: expected ';' after top level declarator t main() { ^ ; 3 errors generated. /srv/wrappers/c-clang: line 5: ./.bin.tio: No such file or directory

abddcccd

char* f(char* str, char ch) 函数里最后缺了字符串结束符'\0'的赋值，所以最终输出：abddcccd
