using this trick, the code becomes struct fast_ios {fast_ios(){ cin.tie(nullptr); ios::sync_with_stdio(false); cout << fixed <<setprecision(10); } } fast_ios_; intmain() {// ...} I think macros are better avoided when alternatives are available. Update 2020/5/21 There is ano...
let's say if I create an instance of classaa, is the fieldjinitialized to 8 which is NOT done by the constructor ? and fieldfis first defaulted to 0, again NOT by the constructor and then initialized to 99 in a constructor And let's say if I create an instance of structbb, is th...
This example shows how a class is instantiated by using the new operator in C#. The simple constructor is invoked after memory is allocated for the new object.
A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

For more information on using class properties as name-value arguments in a function, seeName-Value Arguments from Class Properties. Before R2024a: ThestructName.?ClassNamesyntax did not work with immutable properties. To use this technique in earlier releases, use a separate line to define a na...
