The above are some of the code you practice is mostly familiar with the use of the IF else nested switch statement using the trinocular operator

It is important to note that the scanf function cannot be changed to scanf_s in vs2013 .

In addition, the use of GetChar (), when there will be a flash-back situation

Can be replaced by system ("pause"); The previous need to add the file header include<stdlib.h>
