Answer: A #3f107f.
Letter B would produce a lighter blue-purple color rather than a darker shade of purple. Letter C would produce a very light purple color. Letter D would produce a Black color, making it very dark and not in the range of being purple.
Letter A would produce a darker shade of purple. As explained in the way that the RGB color hexadecimal uses, the amount of each respective color is 2 digits for each color Red, Green, Blue respectively. By reducing the amount of each color in the RGB mode, the output will become a darker shade as the RGB mode is an ADDITITIVE type of color mode.
Answer:
#include <iostream>
#include <array>
using namespace std;
bool isPalindrome(string str)
{
int length = str.length();
for (int i = 0; i < length / 2; i++)
if (toupper(str[i]) != toupper(str[length - 1 - i]))
return false;
return true;
}
int main()
{
array<string, 6> tests = { "madam", "abba", "22", "67876", "444244", "trymEuemYRT" };
for (auto test : tests) {
cout << test << " is " << (isPalindrome(test) ? "" : "NOT ") << "a palindrome.\n";
}
}
Explanation:
The toupper() addition forces characters to uppercase, thereby making the comparison case insensitive.
Answer:
Explanation:
The following code is written in Java and creates all of the methods that were requested in the question. There is no main method in any of these classes so they will have to be called from the main method and call one of the objects created method for the code to be tested. (I have tested it and it is working perfectly.)
class Point {
private int x, y;
public void Point(int x, int y) {
this.x = x;
this.y = y;
}
public double distance (Point other) {
double distance = Math.sqrt(Math.pow((other.x - this.x), 2) + Math.pow((other.y - this.y), 2));
return distance;
}
public int quadrant() {
if (this.x > 0 && this.y > 0) {
return 1;
} else if (this.x < 0 && this.y > 0) {
return 2;
} else if (this.x < 0 && this.y < 0) {
return 3;
} else if (this.x > 0 && this.y < 0) {
return 4;
} else {
return 0;
}
}
}
class Name {
String firstName, lastName;
char middleInitial;
public String getNormalOrder() {
String fullName = firstName + " " + middleInitial + " " + lastName;
return fullName;
}
public String getReverseOrder() {
String fullName = lastName + ", " + firstName + " " + middleInitial;
return fullName;
}
}
Answer:
B. global
Explanation:
A global variable lives on even when a function returns.
