The following is an extremely useful programming algorithm for rounding a real number to n decimal places: Step 1: Multiply the number by 10^n step 2: Add 0.5 Step 3: Delete the fractional part of the result Step 4: Divide by 10^n For example, using this algorithm to round the number 78.374625 to three decimal places yields: Seep 1:78.374625 times 10^3 = 78374.625 Step 2: 78374.625 + 0.5 = 78375.125 Step 3: Retaining the integer part = 78375 Step 4: 78375 divided by 10^3 = 78.375 Using this algorithm, write a C++ function that accepts a user-entered value and returns the result rounded to two decimal places. b.
