(20 points) 5. Write C++ statements that output Democrat if the party affiliation code (party_code) is 'D', Republican if the party affiliation code is R', and independent otherwise. (use switch control structure.) (21 points)

Answer 1

4

a. chr=='B'||chr=='b'

b. x%2==0&&x!=30

c. (y>=3000&&y<=4500)||z==5

d. (x>500&&x<650)||y!=1000

e. (x>500&&x<650)&&y!=1000

5.

switch(party_code)

{

case 'D':

cout<<"Democrat\n";

break;

case 'R':

cout<<"Republican\n";

break;

default:

cout<<"independent\n";

}
