Question

Which of the following suggested changes will fix the error(s) in this code?

double num1, num2;
cout << "Please enter two numbers: ";
cin >> num1 >> num2;
if (num2 == 0)
cout << "Division by zero is not allowed. " << endl;
cout << "Please run the program again. " << endl;
else
cout << "The result is: " << num1/num2;

Answer 1

The error in the code is due to improper formatting and missing statements. The correct code fixes the formatting and adds the necessary statements.

Step-by-step explanation:

The error in the code is that the if statement and the else statement are not properly formatted and indented. The correct indentation should be:

if (num2 == 0) {
cout << "Division by zero is not allowed." << endl;
cout << "Please run the program again." << endl;
}
else {
cout << "The result is: " << num1/num2;
}

Additionally, the #include <iostream> statement is missing at the beginning of the code, which is necessary to use input/output streams. The corrected code would be:

#include <iostream>
using namespace std;

int main() {
double num1, num2;
cout << "Please enter two numbers: ";
cin >> num1 >> num2;

if (num2 == 0) {
cout << "Division by zero is not allowed." << endl;
cout << "Please run the program again." << endl;
}
else {
cout << "The result is: " << num1/num2;
}

return 0;
}
