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.

Color's RGB value indicates its red, green, and blue intensity. Each intensity value is on a scale of 0 to 255, or in hexadecimal from 00 to FF.
RGB values are used in HTML, XHTML, CSS, and other web standards. For more, including visual samples and RGB values, see:
Answer:
The RAM capacity expressed in bytes is
512 million bytes
Explanation:
a) Data and Calculations:
RAM contains 256m words
Each word = 16 bits
1 bit = 0.125 byte
This means that each word will have 2 (16 * 0.125) bytes
Therefore, the RAM contains 256m * 2 = 512 million bytes
b) A bit is 0.125 bytes and a byte is eight times bigger than a bit. This implies that there are eight megabits in every megabyte, and one gigabyte is eight times bigger than one gigabit. The 512 million bytes above are about 488.3 gigabytes, since 1 gigabyte equals 1,024 megabytes or 1,046,576 kilobytes.
Solution :
It is given that :
The digits 0 through 9 in hexadecimal have their usual meanings. But letters A through F function like the digits and it means digits 10 through 15, respectively.
Now the base of a hexadecimal is 16.
Now we know from 0 to 9 
A, B, C, D, E, F
Now the maximum two digits hexadecimal numbers are = F F
So, F F 
= 255
