Question

Complete the following assignment in C++:

Something is wrong with my code. All of the test cases fail. My outputs dont match the required outputs because things arent where they are suppose to be or shouldnt be there at all.

Here is my code:

#include <iostream>
#include <string>
#include <cstring>
using namespace std;
// function prototype
string validatePhone(string);

int main()
{
string pno;
string result;
cout << "Enter a phone number in the following format: (XXX) XXX-XXXX" << endl;
getline(cin, pno);
result = validatePhone(pno);
cout << pno << " -> " << result<<endl;;
return 0;
}
// function to validate phone number
string validatePhone(string phone)
{
string result, sub, exchange, area;
string str;
unsigned int i;
if(phone.length() != 14)
return "Input must be exactly 14 characters ";
else{

if(phone.find('(') == string::npos){
return " Missing character: (";
}

if(phone.find(')') == string::npos){
return " Missing character: )";
}

area = phone.substr(phone.find("(")+1, phone.find(")")-1);

cout<<area<<endl;

if(area.length() != 3){
return "Area code must be 3 characters long: " + area ;
}else{
for(i = 0; i < area.length() && area[i]>='0' && area[i]<='9'; i++);
if(i != area.size())
return "Area code may only contain digits: " + area ;
else{
if(phone.find(' ') == string::npos){
return "Missing a space";
}

if(phone.find('-') == string::npos){
return "Missing character: -";
}

exchange = phone.substr(phone.find(" ")+1, phone.find("-")-phone.find(" ")-1);

if(exchange.length() != 3)
return "exchange code must be 3 characters: " + exchange ;
for(i = 0; i < exchange.size() && exchange[i]>='0' && exchange[i]<='9'; i++);
if (i != exchange.size())
return "Exchange may only contain digits: " + exchange ;

sub = phone.substr(phone.find("-")+1, phone.length()-phone.find("-")-1);

if(sub.size() != 4)
return "subscription code must be 4 characters: " + sub ;
for(i = 0; i < sub.size() && sub[i]>='0' && sub[i]<='9'; i++);
if (i != sub.size())
return "Subscriber number may only contain digits: " + sub ;

return "Accepted";

}
}
}
}

Hi, I have fixed the issue.

THere was extra printing statement.

Please let me know in case of any issue.
