Question
Construct a switch-statement to calculate the cost of produce: 1 - grapes @ $1.99/lb. 2 - strawberries @ $ 1.50/lb. 3 - apples @ $0.99/lb. Use int produce and double pounds as your produce and weight variables. A while-loop is a ________-controlled loop A for-loop is a ________-controlled loop One execution of a loop block is called what? A while-loop that never evaluates to false is said to be in what? True or False: a for-loop executes a fixed number of times? Which type of loop -- for-loop or while loop -- is used when we don't know how many iterations are to be performed? For (i = 0: 2: 20) executes how many iterations?Explanation / Answer
9.
#include <iostream>
using namespace std;
int main()
{
int produce;
double weight,cost;
cout<<"Enter produce and weight";
cin>>produce;
cin>>weight;
switch(produce)
{
case 1: cout<<"Grapes at @ $1.99/lb";
cost = weight *1.99;
break;
case 2: cout<<"Strawberries at @ $1.5/lb";
cost = weight *1.5;
break;
case 3: cout<<"Apples at @ $0.99/lb";
cost = weight *0.99;
break;
default: cout<<"Invalid produce ";
cost = 0;
break;
}
cout<<" Cost = "<<cost;
return 0;
}
10. A while loop is event controlled loop.
11. A for loop is count controlled loop.
12. iteration
13. infinite loop
14. true
15. while loop
16. 11 iterations (0,2,4,6,8,10,12,14,16,18,20)
