Why is it that in the STL it is standard to indicate a sequence of elements in a container by a begin iterator that points to the first element and an end iterator that points to one past the last element?
View 2 RepliesWrite a program that gets a sequence of unsigned integers.the user can enter at most 100 integers.
After getting the numbers, the program allows the user to repeatedly choose one of the three options:
1. swap the location of two entries in the sequence. if this option is chosen the user is prompted to enter the two locations to be swapped.
2. print out the sequence.
3. repeatedly swap two locations in the sequence until getting back to the state before this operation started. then print out the number of swaps performed.
Let assume that there is an array of integer numbers in the range from 1 to N that are located in the ascending order. For example
#include <iostream>
#include <numeric>
#include <iterator>
int main() {
const size_t N = 20;
[Code] .....
How can it be converted using some one standard algorithm such a way that the resulted sequence would look like
1 3 5 7 9 11 13 15 17 19 20 18 16 14 12 10 8 6 4 2
We have to write a function named fibonacci that takes an int indicating the length of the series and then store it in an array of size 20 printing the sequence from largest to smallest. Here is the small bit i have so far:

void Fibonacci( int );

How to draw a hollow triangle given a user input indicating the number of rows.
Eg:
Number of rows = 4
___*
__*_*
_*___*
*******
My idea was to split up the triangle into three parts (first row, middle part, last row) and I've managed to write some code on printing the first and last row of the triangle
Code:
int main() {
//Declaring the variables.
int rows, position;
//Prompts user to enter number of rows.
printf("Enter the number of rows in the triangle: ");
scanf("%d", &rows);
[Code] .....
What to do so that I can print the middle part of the triangle. All I know is that I need to use loops. I've also been told that drawing a flow chart would work but I really don't know how to even begin with a flow chart then transform it into code.
If I have a pointer variable indicating memory location in which we have stored what user entered and the pointer is of type volatile if the user gives the character 'a' twice , then this character will not be fetched twice from the memory but only when the character is changed???
This is the one meaning of the volatile? the other is that the value will be changed without the program itself change it?
unsigned char x1, x2, x3;
size_t ix = 0;
size_t count;
std::string Input = "EFEF9E9475C8C2D938C204EAE058F2B3";

when debug and have a watch on out i get incomplete sequence,
Code:
int main()
{
int n;
int* fib;
printf("
Fibonacci test 1: enter an integer
");
scanf("%d",&n);
fib = fibonacci(n);
printf("fib(%d) = ", n);
for(int i = 0; i < n; ++i){
printf("%d ", fib[i]);
}
What should I do/write for the fibonnaci function Code: int fibonnaci(int size)
I made a fibonacci series with label above it now how to put the label after the first layer because as you can see in the screenshot the label is continuous.

I have to write a program to find the nth number of the Ulam numbers.
It's a bit complicated to explain what an Ulam number is but Wolfram explains it very well here: [URL]
I have to find the nth Ulam number but I don't know what I have to do to get that. My program gives me all the Ulam numbers from a range of 0 to n.
What I want the program to do is tell me that the 49th Ulam number is 243.

I made a program that prints out arithmetic sequence.. but problem is that,
when I enter a(first term) =5, d(differnce)=2.4 and n=3 the program prints out only first two terms not three.. for all the other numbers it works correctly..
I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find
1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).
Q) How to do nested loops?
Q) How to do Array?
Q) How to do Fibonacci sequence?
The next code is right. I mean it works. It gives the sequence of fibonaci numbers ...
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int fibo(int pos) {
if(!pos)return 0;
if(pos==1)return 1;
[Code] .....
But.... when I change the lines:
Code:
int r1=fibo(pos1);
int r2=fibo(pos2);
int r=r1+r2;
For the lines:
Code:
int r=fibo(pos1)+fibo(pos2);
It doesn't work right. Apparently it should work the same.
I'm doing some file input/output work here in C and received this warning during compilation (GCC). My research indicates that this error is in response to white space or a character cancellation function or something like that. I'm not 100% sure exactly what it means. My code works fine, but the following warning does appear.
Code:
warning: unknown escape sequence: '40'
Here's my code (excluding a bunch of comments at the bottom of the file).
Code:
#include <stdio.h>
int main(void){
FILE *file;
file = fopen("Running Practice.c", "a");
fprintf(file, "Testing...
");
fclose(file);
}
I believe the error I received has to do with either the ' ' I used when appending text to my file, or something to do with there being a space in the file name itself.

A sequence point in a C program is defined as "Any point in a program's execution at which it is gauranteed that all side effects of previous evaluations will have been performed and no side effects from subsequent evaluations have yet been performed."
What is a side effect?
I was trying to create a code to calculate the nth number in a Fibonacci sequence, when the nth number is entered interactively.
View 4 Replies View RelatedWrite a C program that calculates the sum and average of a sequence of numbers. Assume the first number specifies the number of values remaining to be entered. If the first number is less than 1, then the program should display an "Invalid Entry ... Please enter a positive number." message.
THIS IS HOW IT SHOULD COME OUT...
Enter the number of values to process 0
Invalid Entry ... Please enter a positive number.
Enter the number of values to process 3
Enter 3 numbers:

my data structures and algorithms professor gave us the following assignment. We are to reimpliment a class we wrote earlier in semester called sequence(which holds a sequence of floats) using a linked list. However I am having trouble with the class's copy constructor and assignment operator, specifically when the sequence is not empty.

I need to implement the fibonacci number sequence. Here is an example output of the program:
Server:Waiting for connection

Client:10
Server:Print 10 Fibonacci
Server:1 1 2 3 5 8 13 21 34 54
Client:1 1 2 3 5 8 13 21 34 54
if Client send value of 5, the output would be 1 1 2 3 5

Given a set of DNA string. Find minimum length string S so that, given DNA strings are subsequence of S.
For example, if given set of string is: {CAGT, ATGC, CGTT, ACGT, AATT} then answer is: 8. Because, ACAGTGCT contains all given DNA as subsequence.
Given n such DNA string (n <= 8), each of length atmost 5. Find out the least length.
Sample:
5
AATT
CGTT
CAGT
ACGT
ATGC
Output:
8
