c++ auto lambda functional code example
Example: lambda c++
#include <iostream>
#include <string>
// returns a lambda
auto makeWalrus(const std::string& name)
{
// Capture name by reference and return the lambda.
return [&]() {
std::cout << "I am a walrus, my name is " << name << '\n'; // Undefined behavior
};
}
int main()
{
// Create a new walrus whose name is Roofus.
// sayName is the lambda returned by makeWalrus.
auto sayName{ makeWalrus("Roofus") };
// Call the lambda function that makeWalrus returned.
sayName();
return 0;
}
