The question has the multiple choices below
A) Input validation
B) output correction
C) compiler criticism
D) output validation
The answer is (A) Input validation
Also known as data validation, it is the correct and proper
testing of any input supplied by an application or a user. It prevents wrongly
formed data from entering the system. Applications should be able to check and
validate every input entered into the system since it is hard to detect a
malicious user trying to gain entry into software.
The compiler translates each source code instruction into the appropriate machine language instruction, an
Answer:
Explanation:
To resolve this problem, first, we need the current date and a pass day, with these two values, we're going to use the formula called "DAYS" this formula returns the numbers of day between two dates, when we get the number of days, only we must multiply the result by 24, in this case, this represents the 24 hours in a day.
Answer:
#include <iostream>
using namespace std;
int main()
{
cout<< rand() % 50 + 100 <<endl;
cout<<rand() % 50 + 100 <<endl;
return 0;
}
Explanation:
The rand() gives you a random number. If you use rand() % 50, it will give you a random number between 0 and 49. Since we are required to have the numbers between 100 and 149, add 100 to this expression. This way, you will have a random number between 100 and 149. Type this expression two times and use "endl" to end with a new line.
