console-game

Create a simple console game in which the computer generates a random math expression like 7 * 9 / 3 and asks the user to solve the equation.

The game must take a level parameter, the level determines the length of the generated equation; for example:

--level 1 68 = 68 17 = 17 40 = 40 97 = 97 58 = 58

--level 2 75 - 54 = 21 62 + 15 = 77 88 / 22 = 4 93 + 22 = 115 90 * 11 = 990

--level 3 ( 21 + 13 ) * 56 = 1904 82 - 19 + 16 = 79 51 * ( 68 - 2 ) = 3366 41 + 55 + 31 = 127 82 * 22 - 16 = 1788

--level 4 99 * 1 * ( 1 + 79 ) = 7920 ( 80 + 84 ) * ( 89 + 65 ) = 25256 54 * 64 * 75 * 68 = 17625600 89 + 10 - ( 8 / 2 ) = 95 12 + 70 + 48 + 39 = 169

--level 5 49 * 11 - ( 33 + 71 - 39 ) = 474 5 / 5 + ( 75 + 91 ) / 83 = 3 42 + 38 + 67 * 37 - 47 = 2512 ( 17 - 10 ) * ( 40 + 67 - 67 ) = 280 91 * 80 - ( 40 * 19 / 2 ) = 6900

Note that level 1 is useless! We just have it for simplicity.

The game starts with a command like ./game --level 3

The numbers in the equations must be integers between and including 1 to 100.

The game must produce equations with addition + and multiplication * operators like ( 21 + 13 ) * 56.

Bonus 1:

The game should print out the simplest form of the expressions (by removing unnecessary parentheses), for example it should simplify (5 + 3) + (8 * 3) to 5 + 3 + 8 * 3.

Add subtraction - operator.

Bonus 2:

Add division / operator.

Make sure the result of the equation is always a positive integer.
