Lambda expressions in C++11 provide a concise way to create anonymous functions. They are particularly useful for passing functions as arguments to algorithms and for use in concurrent programming.
Here is a simple example of a lambda expression that sums two numbers:
auto sum = [](int a, int b) { return a + b; };
int result = sum(5, 3); // result will be 8
