I'd say test patterns.

Also known as a test card, a test pattern is a television test signal that was sometimes broadcasted when the transmitter was active but no program was being displayed on the screens. It was usually used since the earliest TV broadcast and is currently, often used for calibration, alignment and troubleshooting the downstream signal path. The purpose of the test pattern transmission back then was to enable engineers install or repair TV receivers.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
rosijanka [135]

Answer:

#include <stdlib.h>

#include <time.h>

#include<iostream.h>

int main(void) {

   int seedVal = 0;  

   seedVal = 4;

   srand(seedVal);

  /* Solution*/

  cout<<rand() % 149 + 100<<endl;

  cout<<rand() % 149 + 100<<endl;

  return 0;

}

Explanation:

We start with the required include statements to enable use of srand, rand and time functions. I have also added iostream library to use "cout" function.

After that, the seed is initialized using srand(). And then the two rand functions are called with ranges including and between 100 and 149, and printed out.

What conclusion can be made about the state of the program when the while loop terminates? Assume answer is a declared and initi
stellarik [79]

<u>Answer:</u>

<em>1. The loop will run unless the value of answer equals to Capital N.</em> The method equals is “case-sensitive” that is lower case letter and upper case letters are considered different. That “a” and “A” means the same to us, but for the method equals it is different and equals method will return false if the case is not matching.

<em>2. a (int)(Math.random() * (upper − lower) ) + lower </em>

Since we need to consider the lower limit value together to get the desired results we need to add the value of lower limit to the multiplied answer.

<em>3. b while(userGuess != secretNumber || userGuess >= lowerLimit && userGuess <= upperLimit)</em>

Here the program is required to check the while loop and exit when user guess the number or we can say the loop should continue until the user guess the number, so that is why we have taken <em>userGuess!=secretNumber. </em>Next the loop should be exited if it is not within the range or we can say that the loop should run only if the guessed number is within the upper and lower limit.<em> That is why we have opted for the condition userGues>=lowerlimit && userGuess<=upperlimit.</em> Why we have taken && as the operator is that, it’s a range of values so && operator best suit for this kind of logical condition.

What output is produced by the following program segment? Why? (Recall that name.charAt(i) is the i-th character in the string,
vekshin1

Answer:

The output is:

R

M

N

Explanation:

The code snippet print the beginning letter of each word in the given name.

In the for loop snippet:

first the program check if startWord is true and it is true, then it print the value of the character at index 0. Then it check if value of character is empty. If it is empty, startWord is initialized to true else it is initialized to false.

The loop only print a character when the value of i are 0, 8 and 11 which are also the beginning character of a word.
