Homework Answers

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for 4 integer inputs and passes these to the getBest() function call.

2. Your task is to declare and define this getBest() function which has the following details:

Return type - int

Name - getBest

Parameters - 4 integers

Description - returns the highest integer passed

DO NOT EDIT ANYTHING IN THE MAIN

Input

1. First integer

2. Second integer

3. Third integer

4. Fourth integer

This is the given code:

#include <iostream>

using namespace std;

int main(void) {

int a, b, c, d;

cout << "Enter a: ";

cin >> a;

cout << "Enter b: ";

cin >> b;

cout << "Enter c: ";

cin >> c;

cout << "Enter d: ";

cin >> d;

cout << "Highest integer = " << highest;

return 0;

}

Instructions:

1. Your task is to ask the user for a character input.

2. Then, include the cctype built-in library and call the toupper() function. In case you do not know what this function is, this function has the following definition:

Return type - int

Name - toupper

Parameter - one integer which represents the ASCII of a character

Description - returns the ASCII of the uppercase equivalent of the character passed

Extra note - even though it's function definition in the C++ Programming Language Documentation is int toupper(int ch), you can just pass a normal char variable instead and this will just be automatically typecasted/converted to its integer equivalent.

3.Once you get the uppercase equivalent, print this out.

Input

1. Letter to be updated

Instructions:

1. You are provided with the isLeapYear() function which is already declared and defined for you.

2. Your task is to ask the user for a year and then call the isLeapYear function to check whether the year is a leap year or not.

Input

1. Year to be checked

Output

If a certain year is a leap year, print "<INSERT_YEAR_HERE> is a leap year"

Otherwise, print "<INSERT_YEAR_HERE> is not a leap year"

Sample Output:

Enter·year:·2020

2020·is·a·leap·year

This is the given code:

#include <iostream>

using namespace std;

int isLeapYear(int);

int main(void) {

// TODO: Write your code here

return 0;

}

int isLeapYear(int n) {

if(

(n % 4 == 0 && n % 100 != 0) ||

(n % 100 == 0 && n % 400 == 0)

) {

return 1;

}

return 0;

}

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for an integer input n, and passes this value to the function call of the generatePattern() function.

2. Your task is to implement this generatePattern() function which has the following description:

Return type - void

Function name - generatePattern

Parameters - 1 integer n

Description - this function prints a triangular pattern of letter T's based on the value of n. For more information, refer to the output in the test cases

3.DO NOT EDIT ANYTHING IN THE MAIN

Input

1. Integer n

This is the given code:

#include <iostream>

using namespace std;

int main(void) {

int n;

cout << "Enter n: ";

cin >> n;

generatePattern(n);

return 0;

}

1. In the code editor, you are provided with a main() function that asks the user for 2 characters, passes these characters to a function call of the getHigherValue() function, and then prints out the ASCII value of the higher character.

2. Your task is to implement the getHigherValue function which has the following details:

Return type - int

Name - getHigherValue

Parameters - 2 characters to be compared

Description - the ASCII value of the higher character.

3. Hint: Comparing characters in C++ is just like comparing integers.

4. DO NOT EDIT ANYTHING IN THE MAIN

Input

1. First character

2. Second character

This is the given code:

#include <iostream>

using namespace std;

int main() {

char a, b;

cout << "Enter first character: ";

cin >> a;

cout << "Enter second character: ";

cin >> b;

cout << "Result value = " << getHigherValue(a, b);

return 0;

}
