Your professor needs your help to decipher some secret message in a sentence. The secret message is formed by taking the first letter of each word in the sentence, in the order of their appearance. Write the following EXACT function:

/** * FUNCTION SIGNATURE: string getSecretMessage(string str) * PURPOSE: get secret message by taking the first character from each word in the input sentence, in the order they appear * PARAMETER: * str, the input sentence * RETURN VALUE: * The secret message */

Examples:

Input str: "professor can code"

Secret Message: "pcc"

(Note: input consists of 3 words separated by single space. Taking the first character of each word gets you "pcc")

Input str: "professor can code"

Secret Message: "pcc"

(Note: input consists of 3 words separated by multiple spaces. Taking the first character of each word gets you "pcc")

Input str: " "

Secret Message: ""

(Note: input is " " - there are no words there. The secret message is "" since there are no words in the input sentence)

Constraints / Assumptions:

For this problem, you may use ANY C/C++ libraries

Your input sentence is a collection of words consisting of only lowercase English characters ('a' - 'z') and spaces (' ').

There may be multiple spaces between words.

A sentence may consist of only spaces

If there is no secret message to be generated, the function returns ""

Failure to follow the same exact function signature receives -1 logic point deduction

A sentence will contain between 1 and 50 characters

Your main() function isn't graded; only the above-referenced function is

Failure to follow the same exact function signature receives -1 logic point deduction

You can test your function in the following fashion, for example:

int main() { cout << getSecretMessage("professor can code") << endl; // prints "pcc" cout << getSecretMessage(" ") << endl; // prints nothing cout << getSecretMessage("pasadena") << endl; // prints "p" ... return 0; }
