1+1

Step 1: Define the variables: In C++, the first step is to define the variables that will be used in the expression. In this case, there are no variables involved, so we can skip this step.

Step 2: Perform the computation: In this step, we perform the addition operation between the two numbers. In this case, the numbers are 1 and 1, so we simply add them together.

Step 3: Store the result: After performing the computation, we need to store the result in a variable. However, since we don't have any variables in this case, we can skip this step as well.

Step 4: Output the result: Finally, we need to output the result to the user. In C++, this can be done using the "cout" statement. In this case, the result of the addition operation is 2, so we would output "2" to the user.
