C++ program to develop a detailed program using all basic logics .

Write a program that behaves as the program in example 1 on the next page. (In the examples text entered by the user is shown in bold to distinguish it from the text produced by the program.) Test your program carefully with all conceivable input. When and why does it fail? Modify your program to handle more input. It should now work for both example 1 and example 2. You will need to read up on and the input buffer. Pay careful attention to the example output and match the output of your program to them exactly. Note specifically the right alignment of the reals and integers. Demonstrate to your assistant when you think your program is correct. Follow the instructions for how to demonstrate given earlier in the document. You may assume the user never enter letters when the program expects numbers. In the final version you must be prepared the user enters more digits and letters on each line than asked for (example 2). Some students always point out that you cannot read four integers using only one integer variable. But you can. And you shall. Go do your homework on the input buffer (cin,cout). 

Example 1: 

Enter one integer: 123 

You entered the number: 123

 Enter four integers: 12 34 56 78 

You entered the numbers: 12 34 56 78 

Enter one integer and one real number: 4711 3.14159265

The real is: 3.142 

The integer is: 4711

Enter one real and one integer number: 2.71828183 1392 

The real is: ______2.718 

The integer is: ____1392 

Enter a character: a 

You entered: a

Enter a word: calvin 

You entered: calvin 

Enter an integer and a word: 32 students 

You entered ’32’ and ’students’.

Enter an character and a word: Q garden 

You entered the string "garden" and the character ’Q’. 

Enter a word and a real number: three .14 

You entered "three" and "0.140". 

Enter a text-line: The quick brown fox jumps over the lazy dog. 

You entered: "The quick brown fox jumps over the lazy dog." 

Enter a second line of text: That was a pangram phrase. 

You entered: “That was a pangram phrase.” 

Enter three words: Testing One Two 

You entered: “Testing One Two” 

Example 2:

Enter one integer: 123.4 

You entered the number: 123 

Enter four integers: -12 100034 56 0 

You entered the numbers: -12 100034 56 0 

Enter one integer and one real number: 4711 3.14159265 messing up 

The real is: 3.142

The real is: ___1396.000 

The integer is: _______2 

Enter a character: abcd 

You entered: a Enter a word: 124calvin 

You entered: 124calvin 

Enter an integer and a word: 24students here 

You entered ’24’ and ’students’. 

Enter a character and a word: Qgarden 34 

You entered the string "garden" and the character ’Q’. 

Enter a word and a real number: three.14 16.17.18 

You entered "three.14" and "16.170". 

Enter a text-line: AND 1T D03S N0T rea11y matter. 

You entered: “AND 1T D03S N0T rea11y matter.” 

Enter a second line of text: Testing One Two three. 

You entered: “Testing One Two three.” 

Enter three words: Testing One Two three. 

You entered: “Testing One Two”
