You are developing an easycpro program for a robot with two motors and four sensors (two bumper switches and two limit switches) to perform the following tasks: the robot should continue moving until it hits an obstacle. upon hitting an obstacle (any one of the sensors is activated), it should stop, pause, backup, pause, turn and continue. a) explain what is happening in the code outlined by the red box. b) fill in the missing code where indicated. #include "main. h"void main (void){int limit1; int limit2; int bumper1; int bumper2; while (1==1){limit1 = getdigitalinput (5); limit2 = getdigitalinput (6); san josé state universitye10 introduction to engineeringpage 4 of 4bumper1 = getdigitalinput (7); bumper2 = getdigitalinput (8); if(limit1==1 & & limit2==1 & & bumper1==1 & & bumper2==1){setpwm (1, 127); setpwm (2, -127); }else{fill in program here}

Write a method that accepts a string object as an argument and returns the number of words it contains. for instance, if the argument is "four score and seven years ago", the method should return the number 6. demonstrate the method in a program that asks the user to input a string and then passes that string into the method, printing out whatever the method returns.

Data is processed, stored, and transmitted as a series of 1s and 0s. each 1 or 0 is called a(n) . a series of eight 0s and 1s, called a(n) , represents one character—a letter, number, or punctuation mark. data becomes when it is presented in a format that people can understand and use. digital signals are represented by two different , such as +5 volts and +.2 volts. digital data can also take the form of light and dark spots etched onto the surface of a cd or the positive and negative orientation of particles on the surface of a hard disk. data consists of numbers that might be used in arithmetic operations. it can be represented digitally using the number system. data is composed of letters, symbols, and numerals that are not used in arithmetic operations. computers represent this type of data using , ebcdic, unicode, or utf-8. data is quantified using terms such as or kibibyte (1024 bytes), and prefixes such as or mebi (1,048,576), and giga or (1,073,741,824). to reduce file size and transmission times, digital data can be compressed. compression provides the means to compress data and reconstitute it into its original state. compression throws away some of the original data during the compression process. compressed files usually have at the end of the file name and are represented with special icons. these files have to be or unzipped before you can view the data they contain.
