Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be…

Write a program that can calculate the future and present value of an investment given various parameters. When you calculate the future value of an investment, the more years you hold the investment and the higher the rate of return, the more valuable it is. For example, a $1000 investment at 7% return will give you $1070 (1000+ 0.07-1000) after one year and $1144.90 (1070+0.07-1007) after two years. However, because of inflation, that $1144.90 after two years is not worth the same as $1144.90 now. If the inflation rate is 2%, $1144.90 in two years is the equivalent of $1100.44 now-i.e- 102 More generally, the present value, p, of an investment is 1.02² 1144.90 f p= where is the inflation rate as a percentage. Typically, one would add to the investment with annual contributions. Let's say you start with a $1000 investment and add $100 every year. Therefore, after the first year, you will have $1177 - 7% return on $1100i.e. $1000 initial investment + the $100 year one contribution.…

Running the program Your program should take 5 arguments: start annual years return inflation where start is the initial investment amount annual is the amount that is added to the investment every year years is the number of years that the investment is held return is the annual investment return expressed as a percentage inflation is the annual inflation rate expressed as a percentage So, to calculate the future and present value of $1000 investment after 10 years where you add $100 every year with a 7% return and 2% inflation, you give the following arguments and get this output: $ ./fv 1000 100 10 7 2 Future Value: $3445.51 Present Value: $2826.52 Writing the code Starter code is provided for you below int main(int arge, char **argv ) { int a, n double value, present, I, is value= atof (argv[1]); a = atoi (argv[2]); natoi (argv[3]); r = atof (argv[4])/100; i = atof(argv[5])/100; // TODO write your code here printf ("Future Value: $%.2f\n", value) printf("Present Value: $%.2f\n",…
