First, we need to transform the matrix of outgoing

number of outgoing links per page and identifying leaf


nodes:

contains the pages each page points to.


However, what we want is to know which pages


point to a given page. However, we


will still want to know how many links each


page contains (so store that in a separate array),


as well as which pages contain no links at all


(leaf nodes).





@param outGoingLinks outGoingLinks[ii]

Check to see if there is any error or warning which might be causing that.
Reply:Try to run the exe file (of your compiled program) from command prompt .





start -%26gt; run -%26gt; command


or


start -%26gt; run -%26gt; cmd





cd %26lt;path%26gt; //your program folder

C++: Changing a number into a string of chars?

How would I change an int variable which is 12345 into a char array with [1,2,3,4,5]?





Tell be the corresponding library please, if there is one.

C++: Changing a number into a string of chars?
Use sprintf.





char buf[32];


sprintf(buf, "%d", nValue);





where nValue is your int variable.
Reply:How about incorporating a straight c fix:





#include %26lt;stdio.h%26gt;


int yo = 12345;


char buf[30];


sprintf(buf, "%d", yo);





or if you use a char to hold initially 12345, then it is already in an array.





for(int i = 0; i %26lt; strlen(buf); i++)


printf("%c\n", buf[i]);

How I can use graphics.h file on visual c++?

all the time I compile it said this library not exits . anybody can help me what I cant do when It said this library not exits or where is the place where I cant put header file like math.h normally exits but some library not work so where I will put those header file and where I can get that

How I can use graphics.h file on visual c++?
This package does not exist for Visual C++. You'll have to use the standard packages.

C++ string functions help?

I need to write a library similar to the %26lt;string.h%26gt; header file. I need help writing the following functions. They are included in my own class called "string".





void resize(unsigned int, char);


//resizes character array "Buffer" to number specified by


//first parameter


//fills extra space by the second parameter character





void insert(unsigned int, string %26amp;);


//Inserts a string into "Buffer" a character array.


//First parameter: Place to insert


//Second parameter: string to insert.








void remove(unsigned int, unsigned int);


//removes characters from "Buffer", a character array.


//First parameter : Starting position,


//Second parameter : number of characters to remove.

C++ string functions help?
Okay, this is pretty obviously homework. I won't show any code here, but I'll give you an idea how to implement the functions listed.





First, void resize(unsigned int, char); It has to do these things in approximately this order:


Validate int as greater than zero, or the operation is over before it starts. Next, it needs to allocate memory for a new Buffer with the extra space. Oh-oh. How do you find the buffer if it doesn't return a pointer or a reference to it? Better change the return type to char%26amp; or char *. Okay, now the new characters are written into the new buffer and then the old characters ... Oh-oh, we need to know where that things at too. Better include a reference or pointer to the old buffer as a parameter. So we take the old buffer and move the old characters over into the new buffer behind(?!) the new characters. Rats! Do we need to consider that the new characters should always be prepended or appended or does it change?





void insert(unsigned int, string %26amp; old_string, string %26amp; new_string); maybe?





void remove(unsigned int, unsigned int, string %26amp; buffer);





Unless you MUST follow these exact prototypes for your assignment, you may want to consider these modifications.





I think you can work these last two from the first walk through I gave you. They aren't really any different as to the mechanics of the problem, just what information is needed to operate from. Good luck!
Reply:I can understand that. Next time post partial code with specific questions and I (we?) can take the sting out of those sticky points. Sorry to be a drag. Cheers! Report It

Reply:Sounds like homework to me...


And if you can't do these simple things, you are in trouble!


Do it as a for(i=..;i%26lt;..;i++) loop, and use Buffer[i].


(or review the use of pointers: that's the beauty of C)

C.D. Burner?

My CD burner has been working all day, but after I went through and deleted songs that I don't need anymore out of my library, It won't burn. what can be done to fix this?

C.D. Burner?
Don't download Nero unless you want a whole new burning program.





I don't think it's got to do with deleting stuff out of your library, just a concidence(sp?). Maybe the burner cd drive itself?

C program to add two non-negative integers , without using +, -, *, /, ++, --, %?

Assume both the no. be less than 16383,Don’t use any standard library function too (except printf and scanf, for output and input).and without using above mentioned operator anywhere in ur programme

C program to add two non-negative integers , without using +, -, *, /, ++, --, %?
I won't write the code for you, but take a look at what he *DIDN'T* tell you not to use. Conspicuously available are all the bitwise operators. Perhaps a binary manipulation answer? Hmmmm....

I am using Borland C++ 5.5 compiler. I wrote the code and I added #include <graphics.h>,an error displayed

The error says" Unable to open %26lt;graphics.h%26gt;". Is there a missed "graphics" library in the Borland compiler?


I installed "graphics.h" from another site, but more errors appear especially in this library:(





What is the solution? any answer will be appreciated..

I am using Borland C++ 5.5 compiler. I wrote the code and I added #include %26lt;graphics.h%26gt;,an error displayed
Try #include "graphics.h" and put graphics.h in the same directory as your code.
