Chapter 4, Problem 20CP

Explanation of Solution

Given: The following code is given:

string s1 = "Good morning";

string s2 = "Good afternoon";

cout<< s1[0] <

cout<< (s1 == s2 ? "true": "false") <

cout<< (s1 != s2 ? "true": "false") <

cout<< (s1 > s2 ? "true": "false") <

cout<< (s1 >= s2 ? "true": "false") <

cout<< (s1 < s2 ? "true": "false") <

cout<< (s1 <= s2 ? "true": "false") <

To find:Â The output of the code.

string s1 = "Good morning";

string s2 = "Good afternoon";

cout<< s1[0] <

cout<< (s1 == s2 ? "true": "false") <

cout<< (s1 != s2 ? "true": "false") <

cout<< (s1 > s2 ? "true": "false") <

cout<< (s1 >= s2 ? "true": "false") <

cout<< (s1 < s2 ? "true": "false") <

cout<< (s1 <= s2 ? "true": "false") <

Solution:

The following code on being run will display the following output.

G

false

true

true

true

false

false

First, it displays the first character of the string by printing s1[0].

In the next line, the condition, s1==s2, is checked. It evaluates to false, hence †̃falseâ€TM gets printed.

In the next line, the condition, s1!=s2, is checked. It evaluates to true, hence †̃trueâ€TM gets printed...

You are tasked with developing a portable system that can be worn to collect health and fitness data. The challenge is to integrate all functions into the smaller form of an ear clip. The device should include heart rate, movement and temperature sensor and wireless communication with a mobile app. Draw a diagram- hardware architecture of the system- including the selection of suitable sensors, communication modules, and an energy-efficient microcontroller.
