Answer

Explanation:

Step1: Identify syntax - case sensitivity

In C++, cout and cin are case - sensitive. Here, Cout and Cin are misspelled. They should be cout and cin.

Step2: Identify assignment operator usage

The statement number1 + number2 = sum; is incorrect. In C++, the left - hand side of an assignment operator = must be a modifiable lvalue. Here, number1 + number2 is an expression (rvalue), not a modifiable lvalue. It should be sum = number1 + number2;.

Step3: Identify missing semicolon

The statement Cout "The sum of the two numbers is " << sum is missing the << operator before the string literal and also a semicolon at the end of the statement. It should be cout << "The sum of the two numbers is " << sum << endl; (adding endl is optional but a good practice to flush the output buffer and move to the next line).

Answer:

  1. Cout and Cin should be cout and cin.
  2. number1 + number2 = sum; should be sum = number1 + number2;.
  3. Cout "The sum of the two numbers is " << sum should be cout << "The sum of the two numbers is " << sum << endl;.
