![]() Private Many companies and services are beginning to demand a phone number to verify or activate accounts and to use their applications, If you haveįound our SMS service useful, please consider sharing it with your friends using the social buttons at the bottom of the page. Currently are no limits on how often or how many SMS can be sent to the virtual numbers. Send as many SMSs as you wish to activate accounts that otherwise require personal information ![]() Not currently being listed, please check back later as we continuously add new locations and numbers.įree We are doing our best to receive SMS online for free and make a promise to keep it operational without charging money for If you require free online service in a country Best of all, the service will always remain minimal and free. All our virtual numbers can receive messages globally from anywhere in the worldĮven if the sender is in a different country. ![]() Phone numbers are refreshed with new ones every 30 days. The phone numbers are disposable and all messages are discarded after 2-3 days. Your current program does not obey this scheme and generates invalid numbers.Our service receives SMS from all anywhere in the world to our temporary phone numbers in Canada, USA, United Kingdom, France, Sweden, and Netherlands. That three-digit number must start with a number in the range of 2 through 9 and cannot start with a 0 or 1. In that plan, the second grouping of numbers is called that Central office code. In the US and Canada (which, by the formatting of the phone number, seems to be where this is intended to be used), phone numbers are created according to the North American Numbering Plan. You may not yet have learned about objects or classes, but they're one of the main strengths of C++ and something you should learn soon if you haven't already. Use object orientationīecause you're writing in C++, it would make sense to have a class such as PhoneNumber to encapsulate the details of your implementation. A robust program always checks user input and provides error checking and handling. The program appears to assume that the user will enter a valid 3-digit area code, but no provision is made to assure this. The variable input is not very descriptive. This reduces the entire menu to a single call to operator<< because consecutive strings in C++ (and in C, for that matter) are automatically concatenated into a single string by the compiler. Another way to write that would be like this: std::cout << "\n" Std::cout << "\tAvailable numbers in your area." The main function includes these lines: std::cout << "\n" In particular, instead of rand, you might want to look at std::uniform_real_distribution and friends in the header. Consider using a better random number generatorīecause you're using a compiler that supports at least C++11, consider using a better random number generator. Your compiler is probably also smart enough to tell you that, if you ask it to do so. In this code, none of the digit_ variables are ever actually used. Unused variables are a sign of poor code quality, so eliminating them should be a priority. Putting using namespace std at the top of every program is a bad habit that you'd do well to avoid. Here are some observations that may help you improve your code. Then here is an example of using the getrandomdigit function Enter three digits(area code): 203 Here's a visual example of using the digit vars Enter three digits(area code): 203 For instance, if you were to enter an area code, it would just print the same 2 prefixes 10 times, but when you use the function, it gives you a completely random var every time the counter is run until 10. So my question remains, why does it occur when you use the integers that the numbers AREN'T randomly generated. But before I added the function getrandomdigit(), I was using the manually defined "digit" vars in an attempt to generate pseudorandom numbers. So I believe I understand the logic of how the random number generation works. ![]() << getrandomdigit() << getrandomdigit() << getrandomdigit() << getrandomdigit() << "-" << getrandomdigit() This is the code I came up with #include Ĭout << "Enter three digits(area code): " Ĭout << "\tAvailable numbers in your area." Ĭout << "\n\t******************************" Ĭout << "\nPhone number: " << input << "-" << getrandomdigit() << getrandomdigit() I was tinkering around with C++ after about 3 days of learning and decided to make a random phone number generator. ![]()
