answer by C LANGAUGE  (NOT C++ or JAVA):-

1. 

Given  that two int  variables , total and amount, have been declared , write a sequence of statements  that:

• initializestotalto 0
• reads threevalues  intoamount, one at a time.

After each value  is read in to amount, it is added to the value  in total (that is, total is incremented  by the value  in amount).

2.Write a loop that reads positive integers  from standard input and that terminates when it reads an integer  that is not positive. After the loop terminates , it prints out the sum  of all the even integers  read and the sum  of all the odd integers  read. Declare  any variables  that are needed.

3.Write a loop that reads positive integers  from standard input and that terminates when it reads an integer  that is not positive. After the loop terminates , it prints out the sum  of all the even integers  read. Declare  any variables  that are needed.

4.Write a loop that reads positiveintegers  from standard input, printing out thosevalues  that are even, separating them with spaces, and that terminates when it reads aninteger  that is not positive.Declare  anyvariables  that are needed.

5.Write a loop that reads positive integers  from standard input and that terminates when it reads an integer  that is not positive. After the loop terminates , it prints out the sum  of all the even integers  read, the sum  of all the odd integers  read, a count of the number of even integers  read, and a count of the number of odd integers  read, all separated by exactly one space. Declare  any variables  that are needed.

6.Write a loop that reads positive integers  from standard input and that terminates when it reads an integer  that is not positive. After the loop terminates , it prints out the sum  of all the even integers  read and the sum  of all the odd integers  read. Declare  any variables  that are needed.

7.Given  that two int  variables , total and amount, have been declared , write a loop that reads non-negative values  into amount and adds them into total. The loop terminates  when a value  less than  0 is read into amount. Don't forget to initialize  total to 0.

8.Given  an int  variable  n that has already  been declared , write some code that repeatedly reads a value  into n until  at last a number between  1 and 10 (inclusive) has been entered.

9.Two variables , num and cost have been declared  and given  values : num is an integer  and cost is a double . Write a single statement  that outputs  num and cost to standard output . Print both values  (num first, then cost), separated by a space on a single line that is terminated with a newline character . Do not output  any thing else.

10.Write a single statement  that will print the message  "first is " followed by the value  of first, and then a space, followed by "second = ", followed by the value  of second. Print everything on one line and go to a new line after printing. Assume  that first has already  been declared  as a double  and that second has been declared  as an int . Assume  also that the variables  have already  been given  values .

11.Two variables , num and cost have been declared  and given  values : num is an integer  and cost is a double . Write a single statement  that outputs  num and cost to standard output . Print both values  (num first, then cost), separated by a space on a single line that is terminated with a newline character . Do not output  any thing else.

The exercise instructions here are LONG -- please read them all carefully. If you see an internal scrollbar to the right of these instructions, be sure to scroll down to read everything.

 

Given  that an integer  variable  i and a floating-point variable  f have already  been declared  and given  values : 

    Write a statement  in C that displays the values  of i and f 
    to standard output  in the following format:

    i=value -of-i f=value -of-f

 

Two Examples:

Example 1: if the values  of i and f were 25 and 12.34 respectively, the output  would be:

i=25 f=12.34

 

 

Example 2: if the values  of i and f's value  were 703 and 3.14159, (respectively) the output  would be:

i=703 f=3.14159

 

 

Remember: you areGIVENiandf-- that means they arealreadydeclared  and theyalready  havevalues ! Don't change theirvalues  by assigning or initializing them! Just print them out the way we have shown above. Just write onestatement  to produce theoutput .

 

Remember: you don't know what the actualvalues  ofiandfare-- they are unlikely to be thevalues  used in the examples above!

 

Remember: in youroutput  you must be displaying both thename  of thevariable  (likei) and itsvalue .

13.

Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". Any value  that is the same as the immediately preceding value  is considered a CONSECUTIVE DUPLICATE. In this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. Note that the last 3 is not a consecutive duplicate because it was preceded by a 7.

Write some code that uses a loop to read such a sequence of non-negative integers , terminated by a negative number. When the code exits the loop it should print the number of consecutive duplicates encountered. In the above case, that value  would be 3.

15.3.16 (Gas Mileage) Drivers are concerned with the mileage obtained by their automobiles.
One driver has kept track of several tankfuls of gasoline by recording miles driven and
gallons used for each tankful. Develop a program  that will input the miles driven and
gallons used for each tankful. The program  should calculate and display the miles per
gallon obtained for each tankful. After processing all input information, the program 
should calculate and print the combined miles per gallon obtained for all tankfuls.

Here is a sample input/output  dialog: 

Enter the gallons used (-1 to end): 12.8
Enter the miles driven: 287
The miles/gallon for this tank was 22.421875 miles.
Enter the gallons used (-1 to end): 10.3
Enter the miles driven: 200
The miles/gallon for this tank was 19.417475 miles.
Enter the gallons used (-1 to end): 5
Enter the miles driven: 120
The miles/gallon for this tank was 24.000000 miles.
Enter the gallons used (-1 to end): -1
The overall average miles/gallon was 21.601423 miles.

Note that both the gallons used and the miles driven may be decimal values .
