I am supposed to make a program that take a list of integers from the user and to delete the smallest part of it in order to make it sorted in non decreasing order ..
Code: // string::erase #include <iostream> #include <string> int main () { std::string str ("This is an example sentence."); std::cout << str << ' '; str.erase (10,8); std::cout << str << ' ';
Code:
Output:
I don't understand this program. What do these 2 numbers represent? The index of an element in a character array? The 10th character of the array is 'n' and 8th is a "space".
I'm having a problem converting part of a string to an integer.I used strtok to seperate my string and I have also a function for atoi but how to apply it to my strtok function.What i need is to change the char *years to an int.Have a look of what I got:
Code: int main() { char sentence[]="trade_#_2009_#_invest_#_DEALING"; char *word=strtok(sentence, "_#_"); char *year=strtok(NULL, "_#_");; // assigning NULL for previousely where it left off char *definition=strtok(NULL,"_#_"); char *synonyms=strtok(NULL,"_#_");
I have a string that contains a various number of lines which are each separated by and so what I want to do is to put each line into a node in a linked list.The relevant sections in my code are as follows:
Code:
typedef struct line *Line; struct line { char *text; int lineNum; Line next; }
[code]....
Code:
strncpy(curr->text, text[prevPos], subLength);
With this line, I was hoping to make curr->text a string that is length subLength and begins at position prevPos in the text string. Except text[prevPos] is treated as a single character and not a string that begins at that position.
"Type a function that take in a string containing numbers and others characters and print on stdout all the numbers contained into the string, where for number is mean every maximal numerical sequence, of numbers not separed by spaces. Numbers printed on exit must be separated by commas. For example, if i put in the function the string "paje27hg78 2k f562" my function must print:
27, 78, 2, 562 "
So i started my code like so: (I WANT TO NOTICE THAT WE HAVE ONLY USED IOSTREAM AND FSTREAM LIBRARY FOR NOW, SO DON'T USE OTHERS LIBRARY ELSE MY TEACHER WON'T CORRECT MY HOMEWORK!)
#include <iostream> #include <fstream> using namespace std;
I want do delete all occurrences of a char in a given string, but I really don't see my error in the code. Here is how I did it:
Code:
char *input = "example_string"; int len = strlen(input); char *new_line[len]; char bad = 'e'; //the one to delete int i; int j = 0;
[Code]...
I get segmentation or bus errors.. And I also don#t understand the warning I get. new_line is an array of chars, and I am trying to assign to it a certain char.
I have to manage a Clinic. I need to delete a booking (for example, if John said he's coming on March 22nd at 15:30 but then he say he's not going to come, I have to delete that booking so another person can use it).
idSearched: the id of the person that is not going to come. I have a lot of specialties and each one has a list. So I ask for the speciality to delete the node (the node contains John's booking). If I don't find it, I return (-1). searchSpecByID return a pointer to the list where the speciality is. So head will point to the first node of the list. In nodeToDelete I have the node I want to delete.
The program detects OK when is the first in the list and when not, but it doesn't delete the node.
And I want to create a function to print either c or x. However, I don't want to just use a switch or something to figure this out, I want to reference which part I'm outputting.
Now here's the twist
vector<data> dataList;
I need to access element x or c in the vector, but all I pass is the vector and which element, so that I might have something like:
int count = t1; while(count>counter){ Sleep(delay); Int32::TryParse(textBox2->Text,add); result = result + add; counter = counter + 1;
Problem is that sleep stops all program for specified time, Is there an alternative to sleep that would only stop part of code or can i use sleep different way to specify what it pauses?
Is there any way I can clear only a selected part of the screen? (I'm aware of system("cls"))
For example, when you enter a date, and is wrong, could it just errase that input and only say "Wrong try again" without errasing everything else you where doing?
In this case, a function that only errases what is in the while
I am having a little bit of trouble with what should be a simple part in my code. For some reason it keeps looping the name part of the program and I seem to be passing over the problem in the code.
Here is the code:
#include <iostream> #include <string> using namespace std;
I have a character array that includes configuration bits that are 0x00, thus when I try and do a strcat it adds the appended string into one of those spots instead of the end of the array.
I'm writting an algorithm which equals to std::to_string. The inttostring part is fine, and the decimal_part too. But when the number digits > 5, the program loops infinitely.
I have a vector of sets, which I am removing any element which contains a certain value. For example, if I was looking for 2:
[0] 1 2 3 [1] 4 5 6
After the program was run, I would be left with just [0]4 5 6.
This is the code I have been using
auto iter = std::remove_if( clauseVector.begin(), clauseVector.end(),[propagator] ( const std::set<int>& i ){ return i.find(propagator) != i.end() ; } ) ; clauseVector.erase( iter, clauseVector.end() ) ;
I want to know, is there any way I can tweak this code so that it only removes one part of the set rather than the whole thing. For example with above example, I would be left with
The exercise is : Define a class Arc, which draws a part of an ellipse.
Hint: fl_arc()
And the body of the class ellipse is as follows in the book (PPP):
struct Ellipse :Shape { Ellipse(Point p, int w, int h); //center, max and min distance from center void draw_lines()const; Point center()const; Point focus1()const; Point focus2()const;
[Code] ....
And the fl_arc() probably is part of FLTK which I've installed it on my machine.
Now the problem here is that while I don't can see the full version of the body of the ellipse how to do this exercise?
How can I Passe some part of multi-Dimensional Array to a Function; for example only two dimension of three dimension of a an array with 3 dimension. This is because my function is defined for working with 2 dimension arrays.
I want to compare the part of the character array with the scanned input. I've initialized the character array (colourCompare).
What I want to do is, if the input colour matches up with one of the elements in the colourCompare array, it will then read the next value(I did not include "read the next value part"). If the input does not match up, then it goes back to the scanning part.
How to find the biggest column of the matrix (higher of main diagonal) Here is the draft of code that i desighned/ Of cause it has a several mistake. My task is here to create the matrix, allocate the dynamic memory for it, and to find the biggest sum of the column elements that is located over main diagonal. So main points is correct memory allocation, and the sorting to the biggest sum of column higher than diagonal.
