e. None will cause an error

Answer 1

The line that will cause a compiler error is line 6.

Step-by-step explanation:

The line that will cause a compiler error is line 6.

The line if (number >= 0 && <= 100) is missing a variable to compare to 100. It should be written as if (number >= 0 && number <= 100). The compiler needs both sides of the comparison operator to have a value.

The corrected code would be:

#include <iostream>
using namespace std;

int main() {
int number = 5;
if (number >= 0 && number <= 100)
cout << "passed.\\";
else
cout << "failed.\\";
return 0;
}
