Learn about null-terminated strings in C and C++, their significance, and how to work with them effectively.
struct String { String(uint32_t) { /* size of string */ } String(const char*) { /* string */ } }; String s1( NULL ); String s2( 5 ); In such cases, you need explicit cast (i.e., String s((char*)0)). Implementation of unsophisticated nullptr nullptr is a subtle example...

Parenthesizing it worked as expected and assigned a. As usual, parenthesizing of an expression containing = operator is not allowed. Hence the syntax error in (a, b = 6, 9). The syntax of the Walrus operator is of the form NAME:= expr, where NAME is a valid identifier, and expr ...
Attack disruption means making the attackers` job a little bit more difficult, slowing down their operation and obstructing their spread throughout the orgs` network. It is critical because it will give us more time to react and respond, to find the facts and to ...
The token field is replaced with a compiler synthesized backing field. For example, previously, if you wanted to ensure that a string property couldn't be set to null, you had to declare a backing field and implement both accessors: C# Copy private string _msg; public string Message { ...
