I am trying to print all combinations of a string but I couldn't figure out how to do loop for it. Code works only 2-3-4 letters words
I am trying to write a program for printing all the combinations of a string. Why this program is giving the error message.
"First-chance exception at 0x761bc41f in word.exe: Microsoft C++ exception: std::out_of_range at memory location 0x0026f6b4..

I have a minor issue in my program:

When I run the program, it gives:
To search for a specific word, type (Y), to use a dictionary file, type (N):
Sorry, the given input is invalid, please try again:
I can then input the number. Typing n,N,y or Y goes to the next part of the program without any problems, but if I type something else, I get:
Sorry, the given input is invalid, please try again:

I've fiddled about with the code for a while now, but nothing I do seems to work. What is causing it to be printed twice, or why the first getchar() is ignored.
these are the errors that I'm getting from an online c++ compiler

//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:
void iter_swap(char *ptr1, char *ptr2) {
char tmp = *ptr1; *ptr1 = *ptr2;
*ptr2 = tmp;
}
// 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)

Code:

I don't understand how it printing each element of whole string. Like L a s. But I did not declared array.
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 :
cra
t
e
but it should be:
cra
t
e
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.

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

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

Where is the .N=▒ coming from?
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.

A few days ago I got a "bright idea" to see if I could match a string, with an arbitrary length from 1 to 12, to its formulated sequence by using an algorithm to find all possible combinations of the integer combinations from 0 to 9 at each length (1 to 12).
Example: Desired numerical combinations from integers 1 to 3:
At Length 1:
1, 2, 3
At Length 2:
11, 12, 13, 21, 22, 23, 31, 32, 33
At Length 3:
111, 112, 113, 121, 122, 123, 131, 132, 133, 211, 212, 213, 221, 222, 223, 231, 232, 233, 311, 312, 313, 321, 322, 323, 331, 332, 333
And so on until the nth length (in my case a length of 12).
First off, I would like to say that this is not as easy as I thought. I clearly underestimated the problem seeing as I've spent hours attempting to write a working algorithm, but feel like I've made no progress.
Here are a few of my attempts:
Attempt 1:
#include <iostream>
#include <algorithm>
#include <math.h>
#include <string>
[Code]....
I can't exactly explain this one. It works if the length is 2 or less; however, the order of the output is horrendous.
Attempt 3: I tried using recursion, but only found myself getting more and more lost the further I tried developing my function. Cannot find my work for this attempt.
I would really like to figure this out on my own, but I am very stuck as you can see. I also lack time that I can spend working on this since im a full time student.
I need to create a function that outputs all possible binary combinations. I'm really stumped on this. I have to do it with nested loops, and am not sure how to go about it. Below is what I tried so far.
The output should look like this:
00000000
00000001
00000010
00000011
00000100
...
11111110
11111111
Code:
void outputBinary(){
int a[2][2][2][2][2][2][2][2];
for (int i = 0; i < 2; i++){
for (int j = 0; j < 2; j++){

I wanted to create a 5, 3 combinations. i know how to calculate to get the number of combinations 5 3 would have (which is ten), but it seem it's a bit harder for me to print those data ...
View 2 Replies View RelatedHow to find all possible combinations of coordinates on a 2d grid with a given sum. The sum is not fixed!
E.g. N=nxm=25 thats our grid.
The sum=distance between points on a grid.
For two points distance=|(x1-x2)+(y1-y2)| point A(X1,Y1) B(X1,Y1)
My interest is to know how to find the combinations of coordinates with a given sum, it doesn't matter how many points are there.
If i enter the sum e.g sum=7 and the program has to show all possible combinations which gives the sum of 7 the number of point does not play in row they might be two or maybe more.
How to get all the possible combinations for 4 digits from a 5 digit number. I need a pair that has both 5 digits and four digits. their sum must be equal to a five digit user input. i.e.
user input : 14690
output:
14690 has pairs 12345 + 2345
2345 came from 12345
lets say that x = 12345 and y =2345
besides y == x%10000
other formula can i have since if i use % and / i will have a lot of declarations....
I have an integer vector of size "n".
e.g.
std::vector<int> vec;
vec.pushback(0);

vec.pushback(2);

Now I want to generate all possible combinations of size = {0, 1, 2, ... , n}.
{0, 1, 3} is not equal to {3, 1, 0} or {1, 0, 3} or {3, 0, 1}
how to write a password cracking program that will try all possible char combinations for just two chars (without duplicating any combination guesses). Obviously, there would only be 4 possible truth table combinations for two boolean values, but how would a person calculate the number of all possible combinations for two values with 70 different possible chars?
#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
static const char alphanum[] =
"0123456789"
"!@#$%^&*"
"ABCDEFGHIJKLMNOPQRSTUVWXYZ"
"abcdefghijklmnopqrstuvwxyz";
/*
Boolean Truth Table for two values:
p q
-----
T T
T F
F T
F F
Note that there are 70 chars in all specified above.
It will require much more than a simple truth table to try every possible char combination (especially if the password to be cracked is 2 or more chars). Using this guy's code: [URL] ..... as a starting point, I'm writing a program that will crack a password with a length of just 2 chars.
*/
int stringLength = 2;
char genRandom() {
return alphanum[rand() % stringLength];
}
int main() {
std::string password = "Sp";
srand(time(0));

The first line of my input file is going to contain some number "T" which will represent the "combination length" of a list of random words. (In this case, they are Taco Bell items). The first number on the second line represents the number of unique items on the menu to get, and the second number on the second line represents the number of unique items that are supposed to be bought.
Basically the input will look like this: 2 3 2 taco burrito nacho
And the output looks like this: burritos nachos nacho taco burrito taco
This is what I have so far:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
int main(void){
int N, T, K;
char menu[N][20];
