Answer:
Following are the code to the given question:
#include <iostream>//header file
#include <string>//header file
using namespace std;
int main()//main method
{
string region;//defining a string variABLE
while(true)//defining a while loop for input value
{
cout << "Enter the region code(-1 to quit): ";//print message
cin >> region;//input string value
if(region == "-1")//defining if to checks string value
{
break;//use break keyword
}
else//else block
{
if(region.length() != 3)//defining if to check string value length not equal to 3 {
cout<<"Invalid region code. Region code must contain exactly three characters."<<endl;//print message
}
else
{
if(region.at(0) == 'A' || region.at(0) == 'B')//defining at method that checks string value
{
if((region.at(1) >= '0' && region.at(1) <='9') && (region.at(2) >= '0' && region.at(2) <='9'))//defining at method that checks string value
{
if(region.at(0) == 'A')//defining at method that checks string value
{
cout<<"The shipping charge for region is $25."<<endl;//print message
}
else
{
cout<<"The shipping charge for region is $30."<<endl;//print message
}
}
else
{
cout<<"Invalid region code. Region code should start with A or B followed by two numbers."<<endl;//print message
}
}
else
{
cout<<"Invalid region code. Region code should start with A or B."<<endl;//print message
}
}
}
}
return 0;
}
Output:
