With these it helps Welcome to StackOverflow.
printf asks for a string (null-terminated '\0') which as variable is a pointer to char (char*).
code :
char character='k';
printf(&character);
char character='k';
printf("%c", character);

may help you . According to the sh(1) manpage, printf does not require a leading 0 when escaping octal codes. It's simply printf '\100'

Does that help The printf() first parameter is meant to be a string.
In C, the value '1' is pushed onto the stack to call printf. printf is expecting a string, so it starts to treat 1 as an address.

hope this fix your issue What should the code print? 0 or any garbage value or will it depend on the compiler? , the answer is 0. Global variables are initialized to zero.
