Use the fill algorithm to assign the value '\0' to evey element in the specified range.:

const size_t max_fill = 100;
std::string bs("01234567");

fill(bs.begin(), bs.begin()+std::min(max_fill, bs.length()), '\0' );

The range is specified as starting from the beginning of the string and ending at the minimum of the string length or the max_fill constant value of 100.

Priority: P9 Level: L2

Unchecked element access can lead to out-of-bounds reads and writes and write-anywhere exploits. These exploits can in turn lead to the execution of arbitrary code with the permissions of the vulnerable process.
