Most likely it’s False . But look it up just in case
Answer:
A.
Explanation:
Mark Brainliest if correct!
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string
I believe it’s called a virus or a hacker
Answer:
b. an instruction is executed at runtime.
Explanation:
In assembly language, an instruction typically dictates what task to be performed or executed by the processor and this happens at run time.
Closely related to an instruction is a directive which is a special type of instruction that tells the assembler how to perform a particular task and this happens at assembler time.
Instructions dictate what and directives dictate how.
Instructions typically generate machine codes while directives don't.
Examples of instructions are;
i. AND for logical AND
ii. OR for logical OR
Examples of directives are;
i. ORG for origin
ii. EQU for equate
Therefore the only correct option is b. an instruction is executed at runtime.
