I've got this program that I'm working on. Most of the code is from a video tutorial, but I was editing it to be able to search for an element by name. That's working fine, but suddenly the part of the program that prints out all the elements starts in an infinite loop after I input two elements, and search for one.
I have the structure defined in the code below and need to insert a new string into the middle of the string array. I know there is a way to insert a new element with a vector. How to do this. I have tried several variations similar to uniqueList.word.insert(400,"disisdabomb"); but with no luck.
const int maxWordCount=1500; struct wordCountList { string word[maxWordCount]; int count[maxWordCount]; }; wordCountList uniqueList;
these are the errors that I'm getting from an online c++ compiler
// main.cpp:4:10: error: #include expects "FILENAME" or // main.cpp: In function 'void permute(char*, int)': // main.cpp:17:9: error: 'f' was not declared in this scope
I don't understand how to print full_string to a file!// otherwise, I know that it gives the correct output -- 90 strings.
#include <string> #include <iostream> #include <fstream> #include >ios> // line 4 error using namespace std; char full_string[] = "112233";

//iter_swap – it just swaps the elements pointed to by the respective pointers without changing the pointers themselves. so, it's basically equivalent to the function:
// min_element – finds the location of the minimum element that exists in the given range. in this case,
it is the char* pointer pointing to the location of that element. it can be implemented like:
char *min_element(char *start, char *end) { // end is 1 beyond the last valid element if(start == end) return end; // empty range char *min_pos = start; for(char *iter = start+1; iter != end; ++iter)
So I have linked list and function which deletes element if next element is bigger, so my code is working but its not working with first element, in the comment I have wrote code which I would code for checking that first element, but when ever I check it is blowing up all program.
#include <iostream> using namespace std; struct llist { int x; llist *next;
I'm having trouble printing the text in between separators like commas, periods, and at signs. I'm following Jumping into C++ Chapter 19 Practice Problem 2.
This is what I have so far:
Code: #include <iostream>#include <string> usingnamespacestd; int findNeedle (char separator, string inputLine) { int needleAppearences = 0;

And this was my test run output:
Enter the contact info. one, two, three, ,? , one two, th three, Program ended with exit code: 0
I am trying to save 5 persons names to a struct, and then printing them afterwards, shortly before the program ends. I tried to print the char string out right after it has been copied over, and it showed fine, but when i try to write it out right at the end of the program (its in a separate function) the terminal just prints gibberish.
the function looks like this:
Code: int printUser(){ printf("Following patients have been recorded in this session: "); struct database patient1; struct database patient2; struct database patient3;
[Code]...
the output looks like this(as you can se in under structest, that it shows the correct string, it also uses printf):
So I have an array of char called s.This array has many words inside, each one separated by ''.The words are sorted by length (from bigger to smaller).I have have a char matrix with random things inside (it was not initialized) caled mat.I want to copy the first word from the array s to the matrix mat.
Code:
int nlin, ncol; /*number of lines and collumns.*/ int c,l,a,q; char mat [1000][1000]; char s[1000]; }
[code]....
I can't see where this is wrong, but, when i test it, it clearly is not right. for example, if the input is 3 lines and 3 columns for the matrix and the word is crate, the output is :
I am trying to write a program for printing all the combinations of a string. Why this program is giving the error message.

How to print a string in reverse order(for example: "today is Wednesday " to "Wednesday is today"). My professor said we should begin with a null string and build it one word at a time.
#include <iostream> #include <fstream> #include <string> using namespace std; int nwords(string);
i couldnt solve the algorithm exactly. The program asks the user for a string. "Bugun h@v@ cok g'uzel" for example. then the program asks for another string. If that string doesnt exists in the main string program should say there isnt any substring. If it exist then the program should print the remaining part of main string. For example:
Write the first string: Tod@y weather is be'@utiful write the substring : ug >>ugun h@v@ cok guzel write the substring :wldnqwbdbj >>there isnt any substring Here where i came so far
#include <stdio.h> int main() { char mainstr[50],substr[50];
I'm reading in a string from the command line into a char array followed by a series of ints which are read into an int array.
The command line
Code: lab3 word word word 0 0 2 3 results in the following output:
Code: Word: .N=▒ Number of Words: 0 Word: .N=▒word word word Number of Words: 3 Num: 0 Num: 0 Num: 2 Num: 3
Here is the source code:
int main(int argc, char *argv[]){ if(argc < 2){ //command line must have at least three arguments (one //char, one integer) printf("Error: invalid number of arguments
For the last part of this problem, if player 2 loses the game of hangman, I need to display the letters they did get right. In order to do that, I believe that I need to traverse vector v for the elements that exist in the string hiddenword, and then print those characters that match.
I have a global list that contains smaller lists of char arrays. I have an issue where when I'm reading back the inner lists the last element of one list seems to point to first element of the next.
So my data looks like the below (values separated by commas with the pairs separated by tabs. The last pair in a line is the same as the first). When I read the first list back instead of seeing "456.678,678.98" as the last element in the list. I see "435.67,234.98" twice: at the end of the first list and start of the other. I have debugged when the list is populated and can see the correct values going in so I can't figure what's happening.
obstacle_list = op_prg_list_create(); while (fgets(line, sizeof(line), obstaclePositions_traj_file) ) { token = strtok(line, " "); //Pull the string apart into tokens using the
I have an std list of type double.. and the list is always guaranteed to have just 2 elements. I need to get the value of element 2 minus element 1. What is the least amount of code to accomplish that?
I tried this:
Code: list<double> dList; dList.push_back(1.0); dList.push_back(2.0); list<double>::iterator iter = dList.begin(); list<double>::iterator iter2 = dList.end(); double result = *iter2 - *iter;
I'm making my first steps in STL, and I have a few question:
Is there a way to get an iterator to the i'th element in the collection (set or list), instead of just to the end or the begin?
And another question: Let's say I have an iterator, pointing to some element in my collection, and I use erase() (which takes as parameter an iterator that points to the soon-to-be erased element), what happens to that iterator? will it now point to NULL?
My code has been acting odd. I made a function that layers my art resources but only the last tile of my art resource acts the way it should. My character goes behind and in front of the last tile and gets printed correctly. Strangely its really exclusive to the last tiles I print. What I need is to figure out in step by step order what going on with my code sample below and be able to layer the resources.
Here is a small sample of my main function. This is how I do my rendering.
Code: Int main (int arc, char* args[]) { //Move class Move character; //Class Tile & Side Tile Tile *tiles [TOTAL_TILES];
