PLEASE CODE IN C++ OR C

You will write a program to compare state and county information. Yoi have the following structs in your program struct countyf string name: /name of county string *city, /name of cities in county int cities; //number of cities in county int population; /total population of county float avg income ; Java household income float ava house; /ava ousehold price struct state string name; //name of state struct county *c; /name of counties int co nties; number of co nties in state int population; total population f state
