The steps to initialize default values in astructin C++ using the Brace-or-Equal-Initializers are as follows: Let’s have an example. #include<iostream>using namespace std;structhello{bool x=true;bool y=true;bool z=false;bool a=false;bool b=true;bool c=false;}demo;intmain(){cout<<demo.x<<demo.y<<demo.z<<demo.a...
TypeDefault value Any reference type null Any built-in integral numeric type 0 (zero) Any built-in floating-point numeric type 0 (zero) bool false char '\0' (U+0000) enum The value produced by the expression (E)0, where E is the enum identifier. struct The value produced by setting...
Right now, the default field value feature (#132162) lowers anon consts whose types may reference ADT params that the const doesn't inherit. This PR fixes this, so that these defaults can reference ADTs' generics, and sets the generics_of parenting up correctly. There doesn't seem to be...
flatc version 1.8.0 turns this schema: struct S { m:int8 = -1; } into a C++ class with this default constructor: S() { memset(this, 0, sizeof(S)); } That's rotten. Flatc should either generate code that is semantically correct or reject ...

The value of an object that is not initialized or assigned to is indeterminate. Attempting to evaluate such a value leads to undefined behavior.In debug mode, these variables are implicitly initialized to a value that lets you verify the variable was never given a value. In release mode, ...
