Thread: How to input a telephone number and use function strtok to extract?

output should like that:

input #: (909)869-2511
area: (909)
exchange: 869
ext.: 2511
#: (909)869-2511

Code:

#include <iostream>
#include <iomanip>
#include <cstring>
using namespace std;

int main()
{
char sentence[32];
char *tokenPtr;
tokenPtr = &sentence;

cout << "Input Telephone No.: " ;
cin >> sentence;
tokenPtr = strtok( sentence, " " );

while ( tokenPtr != NULL )
{
cout << tokenPtr << '\n';
tokenPtr = strtok( NULL, " " );
}
return 0;
}

You need to tell strtok where things stop in order for it to work properly.

On the other hand, you probably shouldn't use strtok since that will erase the token-splitting characters (i.e., ')' and '-'). You can use strchr to search for specific characters in a string.

Even better, you could ditch C strings and use C++ strings.

this is my first time to use it and the book doesn't tell
how to input string and cout like the very top.
can you help me fix my code? cause I can't find the errors.
