Interview question (2) -- convert string-number of characters inserted

Requirement: Convert the string-the number of characters inserted, such as the aaab character string. The number of characters inserted is changed to aaa3b1. The Code is as follows: /**//*********************************** *************************************
* Conversion string -- number of characters inserted
* For example, aaab is changed to aaa3b1.
**************************************** ********************************/

# Include <stdlib. h>
# Include <stdio. h>
# Include <string. h>

# Define maxcount 2*100 // The length of the input string cannot exceed 100

Char * Transformation (char * Str)
...{
Int Len = strlen (STR );
Char * Buf = new char [Len + 1]; // The number of characters that are stored after the character

Char * P = STR;
Char * q = p + 1;
Int COUNT = 1;
While (* q)
...{
If (* P = * q)
...{
Count ++;
P ++;
Q ++;
}
Else
...{
ITOA (count, Buf, 10 );
Int nbits = strlen (BUF );
Strcat (BUF, q );
* Q = 0;
Strcat (STR, Buf );
Q + = nbits;
P = Q;
Q = p + 1;
Count = 1;
}
}

// Number of the last identical characters
ITOA (count, Buf, 10 );
Strcat (STR, Buf );

Delete [] Buf;
Buf = NULL;
Return STR;
}

// Display menu
Void show_menu ()
...{
Printf ("---------------------------------------------");
Printf ("input command to test the program ");
Printf ("I or I: input string to test ");
Printf ("Q or Q: Quit ");
Printf ("---------------------------------------------");
Printf ("$ input command> ");
}

Void main ()
...{
Char sinput [10];
Char STR [maxcount];

Show_menu ();

Scanf ("% s", sinput );
While (stricmp (sinput, "Q ")! = 0)
...{
If (stricmp (sinput, "I") = 0)
...{
Printf ("Please input an string :");
Scanf ("% s", & Str );
Printf ("Before transformation: % s", STR );
Char * pstr = Transformation (STR );
Printf ("after transformation: % s", pstr );
}

// Enter the command
Printf ("$ input command> ");
Scanf ("% s", sinput );
}
}

 

The running result is as follows:
