Final answer:

The code contains syntax errors and would not compile. Correcting the syntax errors, the answer would depend on whether the code is intended to display the vector's size or its capacity. As provided, it would result in a compiler error.

Step-by-step explanation:

The code provided seems to be intended for use with C++ and the Standard Template Library (STL). However, there are syntax errors in the code that would prevent it from compiling and thus from displaying any output. Assuming that the goal is to create a vector object named pretzel, initialize its size, reserve capacity, and then display either its size or capacity, the correct code should look similar to:

std::vector pretzel(50);
pretzel.reserve(60);
std::cout << pretzel.size(); // Or pretzel.capacity() for the reserved space

As the code stands, it will result in a compiler error because the syntax is incorrect. The correct syntax to initialize the vector with 50 elements should be vector<int> pretzel(50), and to display the size or capacity, one would use cout << pretzel.size() or cout << pretzel.capacity().
