Question

5. (12 points) Consider the following code fragment (part of a program): int index 3; String dna "ACTGTCA char nucleotide dna.charAt (index); Matching: For each term below, write the letter of the ONE choice that best matches the term. Data types Variables Literals Object Method ーParameter nde x a. coumt, nucleotide, and d b. 3 and "ACTGTCA c. int, char, and String d. index e. charAt f. dna na 6. (10 points) a. Wrte a statement that assigns true to the variable fever if the variable temperature is greater than 98.6; otherwise it assigns false to fever. b. On what values of temperature would you test your code in part a? 7. (10 points) Write a method named isValid which receives one parameter of type int, an returns true if it is 0, 1 or 2; false otherwise.

Answer 1

5)

● C) int, char and String : Data types

int , char and String are data types used in C for integer, character and String types of data respectively.

● A) index ,nucleotide and dna : Variable names

index , nucleotide and dna are variable names of values that are used in this program for different evaluations.

●B) 3 and "ACTGTCA" : Literals

3 and "ACTGTCA" are fixed integer and string values respectively in this program called literals.

●F) dna : Object

dna is a String object that is created in this program which is used to call a function called charAt.

●E) charAt : Method

string_name.charAt(parameter) is a method used to return the character at the given position (parameter) of the string_name . In this program character at the index 3 of the string value in dna , ie, 'G' will be returned.

●D) index : Parameter

index is the parameter used for the charAt function in this program.

a) STATEMENT:- (since you didn't mention which language to use, I'm using the default C language as per HomeworkLib rule)

#include <stdio.h>

#include<stdbool.h>

int main()

{

float temperature;

bool fever;

printf("Enter your temperature : ");

scanf("%f", &temperature);

if ( temperature > 98.6 )

fever = true;

else

fever = false;

printf("%d");

return 0;

}

(The bold portion is the answer to the question.. I wrote the whole program, so u can run it for testing)

b) TESTING OF THE ABOVE CODE:

if u enter any floating point number less than or equal to 98.6 , the output will be 0 (false).

If u enter any floating point number greater than 98.6 (ie, from 98.61 to etc.....) ,the output will be 1 (true).

7)METHOD isValid

#include <stdio.h» 2 #include <stdboo1.h» 3/ bool function1(int num) bool x if (numnum 1num2) x true; else x- false; return x 6 12 int main() int a 15 printf( "Enter an integer number:" Nala 16 scanf("%d " , &a ) ; \S printf("%d", function1(a)); return 0 20 b

(line 3 to 11 is the answer to the question., I wrote the whole code so that you can test it by yourself if needed. The program above was a sample program I used to test the code so I just gave the function name as function1 . SO PLEASE CHANGE IT TO isValid WHILE YOU COPY IT.)

I HOPE THIS WILL HELP YOU. PLEASE RATE IF U LIKE IT. THANKS FOR READING
