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.

Rewrite the function in problem using the string class instead of C-style strings. Assume that the function has the prototype statement

int repeat(string);

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 a pointer to a character string and returns the number of repeated characters that occur in the string. For example, the string “Mississippi” has three repeated characters. Do not count repeated blanks in the string. If a character occurs more than two times, it should still only count as one repeated character; thus, “hisssss” would have only one repeated character. Assume that the function has the prototype statement

int repeat(char *ptr);
