In order to create the parameterized constructor in C++, try out the below-given code: #include <iostream> usingnamespacestd; structfolk{ string name; floatheight; intage; folk(string x,floaty,intz){ name=x; height=y; age=z; }
The above code defines a functionprintIntthat takes a void pointer num as a parameter and casts it to an integer pointer using thestatic_cast operator. The function then prints the value of the integer pointed to by the casted pointer. In the main function, an integer variable x is defined...
