C ++字符串使用strtok，strlen和strcat [英] C++ string use strtok, strlen, and strcat
问题描述
您需要编写一个程序，将来自用户的电话号码作为输入并将其存储为字符串值。电话号码由国家代码，城市代码和实际的7位数字组成，用？ - ？分隔。用户可以按任何顺序输入电话号码。您的程序应该能够识别国家代码，城市代码和7位数字，并以下列格式显示。
国家代码 - 城市代码？ 7位数
详细说明：
1.将电话号码作为用户输入。
2.该数字应存储为字符串值。
3.用户可以按任何顺序输入电话号码，例如0092-333-1234567或333-0092-1234567或1234567-333-0092等。
4。程序应该能够从字符串中识别国家代码，城市代码和7位数字，并以正确的顺序显示它。
样本输出1
输入完整的电话号码：0092-1234567-333
国家代码= 0092
城市代码= 333
7位数是= 1234567
电话号码的正确顺序是= 0092-333-1234567
样品输出2
输入完整的电话号码：1234567-321-0092
国家代码是= 0092
城市代码是= 321
7位数字= 1234567
正确顺序的电话号码是= 0092-321-1234567
样本输出3
输入完整的电话号码：300-0092-9876543
国家代码= 0092
城市代码= 300
7位数字= 9876543
电话号码的顺序是= 0092-300-9876543
You are required to write a program that takes a phone number as input from the user and stores it as a string value. The phone number will consist of country code, city code and actual 7-digit number separated by ?-?. User can enter the phone number in any order. Your program should be able to recognize the country code, city code and 7-digit number and display it in the following format.
Country code - City code ? 7-digit number
Detailed Description:
1. Take phone number as input from the user.
2. The number should be stored as a string value.
3. User can enter the phone number in any order for example 0092-333-1234567 or 333-0092-1234567 or 1234567-333-0092 etc.
4. Program should be able to recognize country code, city code and 7-digit number from the string and display it in the right sequence.
Sample Output 1
Enter the complete phone number : 0092-1234567-333
Country code is = 0092
City code is = 333
7-digit number is = 1234567
Phone number in correct sequence is = 0092-333-1234567
Sample Output 2
Enter the complete phone number : 1234567-321-0092
Country code is = 0092
City code is = 321
7-digit number is = 1234567
Phone number in correct sequence is = 0092-321-1234567
Sample Output 3
Enter the complete phone number : 300-0092-9876543
Country code is = 0092
City code is = 300
7-digit number is = 9876543
Phone number in correct sequence is = 0092-300-9876543
推荐答案
你试图这样做的目的是什么？
另外，既然你使用的是C ++，那么使用istringstream分割出来会更好字段而不是传统的C函数。
And where is your attempt to do this?
Also since you are using C++ you would be a lot better off using a istringstream to split out the fields rather than legacy C functions.

你一定是在开玩笑。
好的，笑话结束了。向我们展示你的代码中你被困住的部分，并仔细描述你遇到的问题。
You must be kidding.
OK, joke''s over. Show us the portion of your code where you''re stuck and carefully describe the problem you''re having with it.
