Make up a program (20), three type double variables, respectively from the keyboard input values for them, and then use the Console. WriteLine method output them into a column, the decimal point alignment, to 3 decimal places. (20) make a program, type three Numbers from the keyboard, and find the maximum number with the operator (? :). (20) make a program, type three Numbers from the keyboard, and find the smallest number using the operator (? :). (20) make a program, type a character, and if its a capital letter, turn it into a lowercase letter, otherwise it wont change. (20) enter a character and determine what type of character it is (capital letter, lowercase, number, or any other character) (20) make a program, set the radius of the circle r = 1.2, high h = 1.5, define Pi = 3.1415, and figure out the volume of the cylinder. (20) make up a program, set the radius r = 1.5, the garden column high h = 3.6, the circle ratio 3.1415 is defined as the constant, the circumference of the circle, the circle area, the cylinder volume. Then use the Console. WriteLine method to output the calculation, and the output requires that the text be specified to take the decimal point two digits. For example, the circumference of a circle is equal to x times x times x. (20) make up a program, type in a character, and if the input character is a capital letter, it converts to lowercase.
