Input A B C * + D E / F * - Output (A+(B*C))-((D/E)*F)) Algorithm of Postfix to infix 1. Push postfix notation to the PostfixStack reverse order ( eg. push - * F / E D + * C B A) 2. while there are no data at PostfixStack 3. read one symbol from the PostfixStack 4. if the symbol is an operand 5. push it into the InfixStack 6. else 7. pop the top 2 values from the InfixStack 8. put the operator between two operand 9. Encapsulate the resulted string with parenthesis 10. if there is only one value in the stack That value in the stack is the desired Infix notation.

Write a program that reads the file, then displays the average number of steps taken for each month. (the data is from a year that was not a leap year, so february has 28 days.) your program needs to use at least 3 functions not counting main and display the information in a neat well formatted fashion.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
