Character Functions. Many areas of engineering use problem solutions in which we search for a specific pattern of information in a signal. The following problems develop a set of functions for this purpose.

Rewrite the function from Problem such that overlap of the occurrences of the second string in the first string is allowed. Thus, the string "110101" contains two occurrences of "101." Assume that the function has the following prototype statement:

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

Character Functions. Many areas of engineering use problem solutions in which we search for a specific pattern of information in a signal. The following 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 following prototype statement:

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