In C, structures are uninitialized by default. To initialize a structure you will typically zero the memory allocated to the structure and then set specific members to specific values. If all members are non-zero, you can simply set those members rather than zero the memory first.
In C++, structures are initialized via inline initializes and/or through the class constructor.
