Use
strtoll()(man page):(This is only available in C99 and C11, not in C89.) The third argument is the number base for the conversion, and
0means “automatic”, i.e. decimal, octal or hexadecimal are selected depending on the usual conventions (10,010,0x10). Just be mindful of that in case your string starts with0.
