it's a computer programming c++ .please give me right programming answer

1. Write a program that converts an input grade from 60 to 100 and outputs a converted grade from 0.0 to 4.0 a. Minimum input value is 60, maximum is 100. b. All whole numbers must display as decimals. (0 displays as 0.0 and 3 as 3.0) The solution requires that you create a simple mathematical expression that converts the input value into the output value. Example Output input in bold italics Grade Converter Converted grade (0.0 to 4.0) 2.5 Some example values are (70 1.0, 89 2.9 63 0.3, 96 3.6). 2. Write a program that converts dollars into coins. a. Request a dollar amount as an integer: $5.34 is input as 534 b. Use a constant variable to represent each coin as a fixed value : const int NICKEL=5; c. Use division and the mod function to calculate the number of each coin. Output Example input bold and italics) Change Calculator Enter dollar amount (as an integer): $534 The equivalent in coins: 21 Quarters 0 Dimes 1 Nickels 4 Pennies
