**Hi, this is kind of silly request, can anyone help me with these three C++ progs:**

**I - Predefined number of operation Calculator**:

e.g.

5 + 12 - 3

10 / 3 - 5 /12

The program should ask for the following

1- number of operations

2- the equation

for example

please enter the number of operations

2

Please Enter equation in the form num [op num] then press enter

6 / 2 * 3

9

**II - Unknown number of operation Calculator**:

accept an equation of any number of operatoins ending with the equal (=) operator.

e.g.

6 + 9 - 3 / 2 =

6

2 * 3 + 3 * 2 / 6 =

3

**III - Priority Calculator**:

caculate the (*, /) operations first then (+, -).

e.g.

6 + 2 * 9 - 3 / 2 =

processing

[6 + 18 - 3/2]

[6 + 18 - 1.5]

[24 - 1.5]

22.5

2 * 3 + 3 * 2 / 6 =

processing

[6 + 3 * 2 / 6]

[6 + 6 / 6]

[6 + 1]

7

I really hope that you help me, thanx in advance
