This assignment is a continuation from the previous assignment of CBCP2101. You are required to accomplish the assignment by writing complete codes in C language. Read again the following scenario and fulfill requirements in completing the codes. 

You are required to analyse a problem to calculate and show the output of an interest-bearing investment. All the investment is interest bearing and compounded quarterly (the interest is calculated and added back to the balance four times a year), and is extended for three years.

 The users will input the rate for the investment and show to the users how that investment would progress over the next three years.

 A table showing the investment’s history (see Table 1)– starting amount, interest and ending amount – for each quarter of each year is prepared. It should also show the total interest earned in each year as well as over the three years.

The input will consist of an interest rate to be analysed. Anything less than 5 percent or greater than 20 percent will be deemed an unreasonable rate and should be rejected.

The interest is calculated by multiplying the current balance by the rate by the time period, one quarter of a year in this case. A new balance is calculated by adding that interest to the current balance.
