How do you convert a number that consist of alphabet and number in reverse order?
To reverse a number, first convert the number to a string, then reverse the string. Given your number consists of alphanumeric characters, the number must already be a string so simply reverse the string: #include<string> using std::string; string reverse (const string& s) { string str {}; for (auto c : s) str.insert (str.begin(), c); return str; } int main () { std::cout << "Enter a number: "; string s {}; std::cin >> s; std::cout << "The number in reverse is: " << reverse (s); }

How many different ways can a string of 23 pearls be strung?
The number of different ways to string a necklace of 23 pearls depends on whether the pearls are identical or distinct. If the pearls are distinct, the number of arrangements is (23!) (23 factorial). If the pearls are identical, there is only one way to string them. If there are groups of identical pearls, the calculation would require dividing by the factorial of the counts of each group.

How would you implement a substr function that extracts a sub string from a given string?
substr(string, position [, count]) It extract substring starting from start and going for count characters. If count is not specified, the string is clipped from the start till the end
How to display number in asm?
To display a number in assembly language, you typically convert the number to a string format. This involves dividing the number by 10 repeatedly to extract each digit, storing the digits in reverse order, and then using a system call (like write in Linux) to output the string to the console. The specific implementation can vary depending on the assembly language syntax and the operating system being used. Always ensure to handle any necessary conversions and character encoding for proper display.
