Bug ID: 117035 Summary: ICE in unify, at cp/pt.cc:25410, when specifying lambda expression template argument in partial specialization Product: gcc Version: 14.2.0 Status: UNCONFIRMED Severity: normal Priority:
The lambda expression is a prvalueprue rvalueexpression whose value is whose result object is an unnamed temporary object of unique unnamed non-union non-aggregate(非集合) class type, known as closure type, which is declared (for the purposes of ADL) in the smallest block scope, class scope...

Lambda函式支援IIFE(immediately invoked function expression)語法,意思是利用function expression的方式來建立函式,並且立即執行它,語法如下: (lambda parameter: expression)(argument) 範例中即是利用此語法在Lambda函式定義後,立即傳入參數執行。 範例3: 透過此範例可以知道,當Lambda函式經定義後,沒有進行呼叫的動作,...
You can call a lambda expression immediately, as shown in the next code snippet. The second snippet shows how to pass a lambda as an argument to Standard Template Library (STL) algorithms such asfind_if. Example 1 This example declares a lambda expression that returns the sum of two integer...
In C++11 and later, a lambda expression—often called a lambda—is a convenient way of defining an anonymous function object (a closure) right at the location where it's invoked or passed as an argument to a function. Typically lambdas are used to encapsulate a few lines of code that ...
