Questions: The following code snippet contains an error. What is the error? ``` int cost = 0; cin >> cost; if ( cost > 100); cost = cost - 10; cout << "Discount cost: " << cost << endl; ```

Solution Steps

The given code snippet is:

int cost = 0;
cin >> cost;
if (cost > 100);
{
    cost = cost - 10;
}
cout << "Discount cost: " << cost << endl;

The error is in the if statement. The semicolon (;) after the if condition terminates the if statement prematurely.

Remove the semicolon after the if condition to ensure the block of code within the braces is executed only if the condition is true.

Final Answer

int cost = 0;
cin >> cost;
if (cost > 100)
{
    cost = cost - 10;
}
cout << "Discount cost: " << cost << endl;
