C++ Program to Calculate Simple Interest By Passing Arguments

Percent means per cent (hundreds), i.e., a ratio of the parts out of 100. The symbol of percent is %. We generally count percentage of marks obtained, return on investment etc. Percentage can go beyond 100% also.
For Example − assuming that we have total and a part. So we say what part is what percent of total and should be calculated as −
percentage = ( part / total ) × 100

Algorithm

Algorithm to find percentage is as follows −

C++ Program To Calculate Income Tax Using Default Arguments

START
Step 1 → Collect values for part and total
Step 2 → Apply formula { percentage = ( part / total ) × 100 }
Step 3 → Display percentage
STOP

Pseudocode
Pseudocode for the algorithm can be written as −
procedure percentage()

   VAR value, total

   percentage = value / total * 100

   RETURN percentage

end procedure
