In C, the lambda capture clause controls how external variables are introduced into the lambda function through values, references, or default patterns. 1. The capture list is at the beginning of the lambda expression and is used to capture variables in the external scope for internal use of the lambda. 2. The variable will be copied through value capture ([var]). Modifications in the lambda will not affect the original variable. If you need to modify the copy, you need to use the mutable keyword. 3. By reference capture ([&var]) allows lambda to directly modify the original variable, but there is a risk of dangling references. 4. Default capture mode [=] automatically captures all used variables by value, [&] automatically captures by reference, but should be used with caution to avoid potential errors.
