Line 31:

A [[constructor]] of a class/struct can have an '''initializer list''' within the definition but prior to the constructor body. It assigns initial values to the members of the class/struct object.

Example:

:struct int_complex {int re, im; complex() : re(0), im(0) { }};

struct int_complex {

int re, im;

:struct int_complex {int re, im; complex() : re(0), im(0) { }};

};

Here, the construct " : re(0), im(0)" is the initializer list.
