variable will contain a value, but there is no way to know exactly what the value is. In addition, each time the program is executed, the value of the variable may change. This has the potential to produce intermittent episodes that are particularly difficult to track. Look at the following code fragment:
if (bvalue)
//Do an
else
//do B
If the bvalue is an uninitialized variable, the result of the IF statement cannot be determined and two branches may execute. In general, t

C + + calls library functions, if the header file is not properly defined, there may be clearly a function in the obj file exists, but the link failed, the following error occurred:
Undefined reference to ' xxx '
The problem occurs because the C library function is compiled into an obj file and differs from C + + for the processing of the function symbols. Because C + + functions support overloading, the processing of function symbols is more complex, and c is often not decorated.
For examp
When C calls the library function of C, if the header file is incorrectly defined, a function may exist in the obj file but the link fails. the following error occurs:Undefined reference to xxxThe cause of the problem is that the function symbols in the c library are different from those in the C library when the function is compiled into the obj file. Because C Functions Support overloading, the processing of function symbols is more complex, and c is often not modified.For example, there are f

Each part may contain in any number of solid bodies. each solid body is defined by a set of faces and edges. each face contains a reference to the body it belongs to and a list of edges that define the face. each edge will also contain a reference to the owning body and a list of faces that are defined by the edge. NX Open makes it very easy to find the bodies in a part and then to find the relationships between the faces and edges that are used to de
