C program design exercise question parsing has a string containing n characters. Write a function to copy all the characters starting from the m character to another string.

Code block:

#include
void cut (char * s, int x); // Define the cut function
int main ()
{
     char str [20], * p = str;
     int m;
     printf ("Please enter string:"); // input string
     gets (p);
     printf ("Please enter cut number:"); // Enter the number of characters to start cutting
     scanf ("% d", & m);
     cut (p, m); // Call the cut function
     return 0;
}
// Cut function
void cut (char * s, int x)
{
     char * i, cc [20], * j = cc;
     for (i = s + x-1; * j ++ = * i ++;);
     printf ("New string:% s \ n", cc);
}
