Anonymous said...: Can i get some help in writing code to answer these two questions. Thanks

Call the function change() from main() three times and print out the contents of the variables quarters, dimes, nickels, and pennies after each function return.
First Call--pass in the total value $1.88 and on return print the contents of the variables.
Second Call--pass in the total value .32 and on return print the contents of the variables.
Third Call--ask for a total value input from the keyboard and on return print the contents of the variables.

Output should look like:
TOTAL VALUE ENTERED: 1.88
7 quarters
1 dime
0 nickels
3 pennies
and not:
TOTAL VALUE ENTERED: 1.88
7 quarters
18 dimes
37 nickels
188 pennies

2. Write a C function named
liquid() that is to accept an integer number and the addresses of the variables gallons, quarts, pints, and cups. The passed integer represents the total number of cups, and the function is to determine the number of gallons, quarts, pints, and cups in the passed value. Using the passed addresses, the function should directly alter the respective variables in the calling function. Use the relationships of 2 cups to a pint, 4 cups to a quart, and 16 cups to a gallon.
Include this function in a program, printing the results after the function has run.
If the user enters 27 cups, the output should be:
1 gallon
2 quarts
1 pint
1 cup
and not:
1 gallon
6 quarts
13 pints
27 cups; 10/17/14, 1:10 AM

Write a program to read lines of text up to EOF, and then print them out in reverse order. You can use getline to read each line into a fixed-size array, but you will have to call malloc and make a copy of each line before you read the next one.

Royalking said...: i want c programe for ( Adjacency List A graph is abstractly a collection of vertices which are labelled by
non-negative integers, and a collection of edges. A graph called an
undirected graph if we talk of merely the presence of an edge between
vertices i and j, rather than its direction.

For example, the following is a graph:

In this problem, you are given the edges in an undirected graph. An
edge is a pair of non-negative integers (i, j) which indicates that
the vetex i is connected to vetex j by an edge.

Afterwards, you will be given a vertex number n. You have to output
the list of vertices which are connected n by an edge, in the order in
which the edges were input.

Input

You are given the following.

1. The first line contains an integer, E, between 1 and 1000

2. This is followed by E lines, where each containing a pair of
numbers i and j where i and j are both non-negative integers <=
34,000. No edge will be listed more than once.

3. The last line contains a non-negative integer n <= 34,000. n is
assured to be a vertex listed in one of the E lines in part (2).; 11/6/14, 9:25 AM

I got a hard homework to any help pleas...
I have to write program that receives (a,b) 2 int number , a>1 , b>1 , b>a
the program should find out factor between 2 and b-1, this factor divides max numbers between a and b includes b.
the program prints all factor like what I explained .
for instance > if a=2 and b=10 > the program prints 2 because 2 divide max numbers between 2 and 10.
another instance > if a=17 b=18> the program prints 2,3,6,9,17 because each number of them divide just one number that is 18 or 17 .

Please help me answer this question:
where t is the time since the power failure. Your program should prompt the
user to enter how long it has been since the start of the power failure in whole
hours and minutes. Note that you will need to convert the elapsed time into
hours. For example, if the user entered 2 30 (2 hours 30 minutes), you would

Problem : Between Devil and Deep Sea
A band of pirates have made loot. By their misfortune though, instant Karma is delivered. While they are travelling a treacherous route in the high and the deep seas they are also haunted by a devil, perhaps a spirit who suffered at their hands previously. The pirates now have to make tricky decisions. They run forward to save themselves from the Devil, but the deep seas force them backwards. There is a danger of falling in a whirlpool if they move forward rashly and there is a danger of being caught by the Devil if they move too much back. But move they must.

First they recede backwards B meters and then advance forward F meters, in a straight line. They cover 1 meter in T units of time. This backward and forward movement is performed repeatedly by the Pirates because they have panicked.

Your task is to find out if they will perish at the hands of the Devil or they will get sucked into the whirlpool of the Deep Sea and in how much time. It is also possible that by good fortune they might survive. Write a program to calculate the outcome; 8/8/15, 10:17 AM

Cobbletown has a lottery (a small version of California's Lotto) in which players guess four number between 1 and 9. Larry likes to play and thinks he has a scheme to pick winning numbers. He keeps a history of past winning numbers in a text data file. Larry thinks that if a number hasn't occurred recently then it is more likely to show up as a winner. (Obviously Larry isn't familiar with the statistical fact that each number has an equal likelihood of being picked, since each week's drawing is an independent event). Larry wants us to write a program to assist him in his wacky scheme.
INPUT REQUIREMENTS
The lotto history data: a file of unknown length, with four integers per line. Each integer is in the range 1 to 9.
OUTPUT REQUIREMENTS
1. The four least frequently occurring integers in the history data. (That is, counting all the weeks, the four numbers that appeared fewer times than any others).
2. The one integer with longest time since last occurrence. (That is, if you count backward from now, the number for which you count the most weeks since it occurred).
FUNCTIONAL REQUIREMENTS
(You may assume that no data validity checking is required).
1. Determine and display the four integers which occur least often in the history data. Note: To make the problem easier, if there is a tie between two or more numbers for fourth place, it doesn't matter which one is printed. 2. Determine and display the integer which has gone the longest without appearing in a winning sequence.
At a minimum your program must work correctly for the following sample data.
