What if -1 is assigned to a unsigned variable in C plus plus?
If you assign -1 to a unsigned variable it will contain the biggest number its able to hold. For example if you assign -1 to a unsigned int it will be 4294967295 as its the biggest number a unsigned int can hold.
What is a program that calculates the sum of any 5 digit integer number entered by user?
#include<iostream> unsigned sum_of_digits(unsigned num) { unsigned sum = 0; do { sum += num%10; } while (num/=10); return sum; } int main() { unsigned number = 12345; unsigned sum = sum_of_digits (number); std::cout << "Sum of digits in " << number << " is " << sum << std::endl; }

What is the program for palindrome numbers from 500 to 100?
#include<iostream> // forward declarations... unsigned reverse (unsigned, const unsigned base = 10); bool is_palindrome (const unsigned); // the program... int main (void) { const unsigned max {500}; const unsigned min {100}; std::cout << "Palindromes from " << max << " to " << min << std::endl; for (unsigned num {max}; num>=min; --num) { if (is_palindrome (num)) { std::cout << num << std::endl; } } } // Returns the reverse of a number using the given base (default: base 10) // Note: trailing zeroes do not become leading zeroes so reverse (100) returns 1 not 001. // However, the reverse of 0 is obviously 0. unsigned reverse (unsigned num, const unsigned base /* = 10 */) { unsigned rev {}; // zero-initialised while (num) { rev *= base; rev += num % base; num /= base; } return rev; } // If the reverse of a number is the same number, that number is a palindrome. // All single-digit numbers are palindromes, including 0. bool is_palindrome (const unsigned num) { return num == reverse (num) ; }
Which one is equivalent to multiplying by 2Left shifting a number by 1 or Left shifting an unsigned int or char by 1?
The second.
Difference between signed number from unsigned number?
a signed number is one that can be negative (have a sign) whereas an unsigned number will only be positive. due to less information, you can double the largest number storable in a signed integer to get the data available in an unsigned integer. However, PHP doesn't have unsigned integers, they're all signed.
What if -1 is assigned to a unsigned variable in C plus plus?
If you assign -1 to a unsigned variable it will contain the biggest number its able to hold. For example if you assign -1 to a unsigned int it will be 4294967295 as its the biggest number a unsigned int can hold.
