assist in the management of globals. Explain how poor naming practices for variables can lead to "holes" in the scope of a variable. (1 mark) If an int tom, has function scope a hole can be made inside this function by the declaration of char tom inside of a while loop scope. This poor naming convention leads to very difficult debugging and maintenance coding. Explain why a compiler may have to insert "padding" bytes into C/C++ structs. (1 mark) Many CPU architectures have addressing limitations, ie an 8 byte data structure must be located at an address divisible by 8. Therefore some c/c++ structures may need padding inserted by the compiler to allow for this. Explain the role of "unions" and illustrate the code for using the appropriate member of a union. (1 mark) Code using a union is typically a function that takes a union (or a union*), checks in some way to find type its working with, and then calls appropriate processing function.void DoProcessing(Example anExample){ switch(anExample.fType) {case kCOORDTYPE: ProcessCoord(anExample.fT1.fX, anExample.fT1.fY); break;case kCHARKEYTYPE: ProcessCharKey(anExample.fT2.fN2); break;…Explain why "typedefs" fail to offer much type security. (1 mark)Typedef type and original type are not distinguished by compiler Sketch either the C or C++ code that would allow calling code to first create a data structure referenced by a pointer, and then pass the pointer to a function in such a way that the called function can if necessary substitute a new object for the object originally referenced by the caller's pointer. (2 marks) struct cake;void Mix(cake*); …cake* mud = new cake;Mix(mud);…Explain why the following code is erroneous: char *GetName() { char buff[256]; // code prompting user for input and reading a string into buff ... return buff; } Returns an automatic variable which would fall out of scope wh...
