Character Functions: Pattern Recognition. Many areas of engineering use problem solutions in which we search for a specific pattern of information in a signal. Problems develop a set of functions for this purpose.

Write a function that receives pointers to two character strings and returns a count of the number of times that the second character string occurs in the first character string. Do not allow overlap of the occurrences. Thus, the string “110101” contains only one occurrence of “101.” Assume that the function has the prototype statement

int overlap(char *ptr1, char *ptr2);
