C++ :: Read HTML Code - Count / Sort And Print Out Only First 10 Frequently Used Attributes
Mar 14, 2013
I have to write a c++ program to read html code and do bunch of stuff. One thing that i have to do is to count the no of attributes and sort them in descenting out and print out only first 10 frequently used attributes. I counted them using maps and sorted them using multimaps but now dnt knw how to print only 10 elements
for(std::map<string, int>::iterator it = Element.begin(); it != Element.end(); ++it)
Elements.insert(pair<int, string>(it->second, it->first));
for(std::multimap<int, string>::reverse_iterator it = Elements.rbegin(); it != Elements.rend(); ++it) {
cout << "Element: " << it->second << " : " << it->first << endl;
}
This is how i did it . How to display only 10 elements and not all the elements.
This time I need to generate random shapes (circles, rectangles, squares, and ellipses) with random attributes with C, to html.
I am able to create specific shapes with random attributes, but I am unsure how to have the function create a random shape...
Also, the function "box" is meant to create a black border around the shapes. It does this, but I do not know how to make it so that the other shapes do not show up along the lines of this "box."
I guess it appears that certain shapes are "layered" over top of others? ie. My circles/ellipses always show up on top of the rects/squares/box.Currently I have this:
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.
My C programming class wants us to write a program to read integers into an array, sort the numbers and print out the occurrence of each number. I've tried everything that I can think of but the core dump is still occurring.
void countValues ( FILE *inf, int list[], int size ); /* Function prototypes. */ void printFrequencies( const int list[], int size ); int main (void) { int status = EXIT_SUCCESS; /* defaulting status to success. */ FILE *inf = fopen( "numbers.txt", "r" ); /* input data file */
Suppose I have a txt file that I want the contents printed to the console in such a way that every five words are colored blue and the following five are red. How do I accomplish such a task? I am currently only able to print the contents of the file in regular color using ifstream.
write a c++ program that reads an unknown number of integer values and then print count, sum and average of odd values, even values, positive values, negative values!!
How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.
Here I want to connect to website every 60 minutes and fetch only first 100 lines of the run.txt file as mentioned above. How can I do this using C++ and asynchronous winsock ???
Code: #define WIN_OS #define _DEBUG_PRINT(X) /* X */
I am writing an MFC app in Visual Studio 2012 that will open a JPG file as binary and read all the contents to a CString.
I am able to read it to a std::Vector, but that doesn't work much as i need to pass all the binary content as a MFC CString to another function.
More Update:
Let me explain the problem a little more deeper.
I am trying to call a JavaScript (JS) function in a HTML page and then want to pass the binary date. The C++ function that calls the JS is given below.
The 1st argument is the JS Function Name and 2nd is the one to pass the Binary Data. 1st argument works fine as i am able to call the JS fucntion called "LoadImage" without any problem. Problem is with 2nd argument that's supposed to take the Binary data of the JPG file.
If i try to pass a std::Vector or std::string then it will give me an error.
But it's happy if i pass CString. But then with CString there's a problem with NULL characters.
Actually my plan is to pass the binary of a JPG to a JS function and let it display the JPG in the HTML page.
Can i typecast a Vector or std::string to a CComVariant*?
I have the following code to print a string to the LCD using my PIC32 Starter Kit; I have made this code work with success. I cannot, however, make the LCD print numbers.
#include<p32xxxx.h> #define LCD_PRT PORTE //LCD DATA PORT //#define LCD_DDR DDRE//LCD DDR //#define LCD_PIN PINE//LCD PIN

I want to change the original code as little as possible, don't worry about my header files - they are fine.
I'm redesigning some code and I'm wondering what the best ways to store and access certain data is. The characteristics are as followed:
1) Based on data from a file, a distance matrix (N x N) is calculated. 2) Once the matrix is complete, the data will never change (unless a new file is read, but I can work around that by iteratively calling the problem with a new datafile on as command line parameter). 3) The data from the matrix is accessed billions of times from pretty much every other line of code.
In my old version, I had a class "Data" which a sub-class "Data::Distance" and I would put a reference in every other class that needed it. Now, my class hierarchy will be much flatter (basically all logic will be in one class; other classes will be POD structs).
Given the characteristics of the Distance table, is there a way to store them in a very efficiently-accessible way? Does it matter if it's stored in the main class where all the action happens in contrast to being a different class? Does making it static improve the performance? Casting it to const? Anything?
Again, the data is accessed billions of times so even minor differences can save a lot of time.
Write a count controlled loop than can print "i" char. The user is supposed to input a integer and that integer is how many asterisks there is on the blade, in this case it is 5.
* * ** ** **--------------- ******* ** ** ** * ** * -10 Rows high ** -blade always connects on second row of handle ** ** ** **------------------
I'm trying to write a code that takes two arrays from the user (presumably in ascending order) and then passes the sizes of both arrays and a pointer to each to a separate "int* mergeArrays" function that will merge sort the two. I've written a lot of the code, but I can't get it to compile. I get errors: lab6.c: In function "main":
lab6.c:31:14: error: expected expression before "int" mergeArrays(int* firstArray, int size1, int* secondArray, int size2); ^ lab6.c:31:14: error: too few arguments to function "mergeArrays"
I seem to get an error after int main (void) saying 'a function definition isnt aloowed here before { token? And then also at the end of main saying 'expexted } at end of output?
My programme is trying to create a random array of 100 ints between 0 and 250, sort them and print them.
Here is my code:
#include <iostream> #include <stdio.h> #include <stdlib.h> #include <time.h> #include <cstring> void bubbleSort(int *array,int length)//Bubble sort function { int i,j; for(i=0;i<10;i++)
I'm trying to code a program to read the user's input and have it:
-count vowels -stop counting vowels after '.' or '?' (ie. abcdjwef is 1 a, 1 e; while fje.fwdfeiii is just 1 e) -closes when ENTER is pressed after a '.' or '?' is found (ie. closes after 'abacds. ENTER' as well as 'as.fefsdf ENTER') -display the number of vowels
Is there any way to do this with only 'cin >> userInput' and a while loop checking for punctuation?
I have a .txt file that contains, together with a few characters, columns of values that I want to save in different files like is written in the program (file 1, file2, file3 - a with x, b with y, c with z). The pattern of the source text file is like this:
Until now I could manage to split the files, but the output gives me only zeros. First the program count the number of lines of the read text file, then it should display the desired columns of double values in three other .txt files.I've got for the three .txt files columns like this:
I am supposed to read(scan) data from a folder with multiple(21578) text files, and file names are numbered from 1 to 21578,and read each word that occurs in a text file, and count the number of times it occurs in the entire folder,i.e; in all the files how do i go about it? I've tried this so far..but it isn't working..
I am suppose to make a program that reads in data from a text file (integers only) and sorts them as it inserts them into an array of size 10. I did this using an insertion sort, which worked great. But now I am being told that I need the function has to read ALL of the numbers in the text file, not just the first 10, and I am not allowed to store them THEN sort, it has to be sorted as being stored.
I have a pre-declared array which sorts strings to it's alphabetic order and want to change it so it reads from stdin.
char *array[] = {"aaa", "ccc", "bbb", "ddd"}
I tried doing something like this:
for (i = 0; i < length; i++) scanf("%s", &array[i]);
I just can't bring it to work. Another thing is, the input is a a bunch of strings separated by commas and ends with a period. Since I have to make a working C model which gets translated to assembly language later on I can't use functions like strtok.
