C# :: Comparing String Arrays To String

Mar 26, 2014

My program will scan a message sent over Steam (An online game distributor ) and I want it to check if the Message contains one of the elements in the array. I want it to compare the String of the message to the values in the String array. I have tried looking into it but have unfortunately found nothing that would go along with my program outline. Here is my code so far:

if (add == true) {
string[] itemNames = { "keys", "tickets", "nametags", "descriptiontags" };
string[] splitmessage = message.Split(' ');
foreach (string word in splitmessage) {
int strNumber;

[Code] .....

I am hoping for this to look like the picture of the code I wrote in the Attachments. [URL] .....

C++ :: How To Do Loops With String Arrays

Oct 23, 2014

understanding how to do loops with string arrays.

If I have few string arrays with some elements, for example:

string pizza[3]= {"ham", "tomato", "chees"};
string pasta[3]= {"tomato", "chicken", "olive"};

I wonder how, if I was to ask user for example:

string ingredient;
cout << " Please type an ingredient: ";
cin >> ingredient;

If user was to type in tomato, how can I loop it, to get an output like:

Pizza and pasta have tomato as an ingredient.

Is there any other way, to get the same result for this kind of problem.

C/C++ :: How To Sort String Arrays Alphabetically

May 9, 2014

I have a homework assignment in C++ where I have to: "Write a program which asks user to input 10 students names. Store them in an array. Convert all the names to UPPERCASE without using any built-in functions. You must write the function to do that yourself. Lastly, sort the name in alphabetic order."

Here is my code so far, but my program won't compile, and the message it gives me is gibberish.

#include <iostream>
using namespace std;
void sortNames(string name[], int cap);
void toUpper(string name[]);
int minIndex(string name[], int i);
void sort(string name[]);
void swap(string name[], int i, int j);

C/C++ :: Sorting And Searching Two Arrays (int / String)

Apr 2, 2014

Write a function to read and display the contents of names and marks. You then ask the user for a name and using the linear search return the index to the user. If -1 is returned then the name is not in the file. Otherwise write out the name and mark for that student.

Next, sort the arrays, write them out and then ask the user for a name to search for. This time use the binarySearch to return -1 or an index. Display the student's name and mark if found.

void getNames(ifstream& inStream, string names[], int marks[], int numElts);
int linearSearch(const string names[], int numElts,string who);
int binarySearch(const string names[], int numElts,string who);
void selectionSort(string names[], int marks[],int numElts);
void displayData(const string names[], const int marks[], int numElts);
[Code] ....

Now I have worked up some stuff in parts but I am so lost and confused with these specific requirements: Previous questions asked me to sort out a linear search, a binary search and

LINEAR SEARCH:

int searchList(int list[], int numElems, int value) {
int index = 0; // Used as a subscript to search array
int position = -1; // To record position of search value
bool found = false; // Flag to indicate if value was found

C/C++ :: Comparing Two String Arrays For Unique Words?

Oct 2, 2014

I'm looking to take in an array of less than 50 strings, and I want to find all of the unique words in that array (omitting the words that are repeated) and then outputting the unique words and unique word count. My code compiles, but my unique array is couting all of the words contained in the original array regardless of uniqueness.

#include <iostream>
#include <string>
#include <stdio.h>
#include <string.h>
using namespace std;
int main() {
cout << "Please type in some words." << endl;
cout << "Type END and return when you are finished." << endl;

[code].....

This is what I get back.

You typed the following 14 words: red, green, blue, red, red, blue, green, blue, orange, red, reg, apple, banana, banana, END,

You typed the following 0 unique words: red, green, blue, red, red, blue, green, blue, orange, red, reg, apple, banana, banana, END

I'm not worried about the unique count yet, I just want to get the unique array containing the correct strings.

C :: Handling Strings In 2 Dimensional Arrays / Multilingual String Organization

Jan 9, 2015

I have a firmware application that works well where I display simple text messages on an LCD screen. At the moment, the User Interface is only in English and I have the text strings simply declared as follows:

Code:
static char msg1[] = " Welcome ";
static char msg2[] = " Data Read ";
//etc...

I want to add a variable that can set the language dynamically from an external device, and so I thought I could do the following:

Code:
#define ENG 0
#define FRE 1
#define GER 2
//...
static char msg1[ENG][] = " Welcome ";
static char msg2[ENG][] = " Data Read ";

[Code] .....

writeLCD(msg1[cLang][]); When I try to compile the above I get a compiler error at the "static char msg..." declarations. The error is: "error: array type has incomplete element type"

Is this method valid, but I have a simple syntax problem with the arrray declarations? Or is this method unworkable and I should find a different method?

C++ :: Using Arrays As Sources Of Data For Arrays In A Structure?

Feb 6, 2014

I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.

I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.

How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)

Code:

int _tmain(int argc, _TCHAR* argv[]) {
int comm = 10;
int targ = 5;
int death;
struct AI_WORDS

C :: Assigning Values To Arrays / Printing Arrays

Jul 1, 2014

Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.

I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?

Code:
#include<stdio.h>
#include<stdlib.h>

int main () {

C++ :: Ranged For Loop With Arrays Of Arrays

Dec 17, 2014

int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }

Why do we name it row instead column?

int arr[row][column]

Wouldn't this be like

int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}

It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?

C++ :: Dynamic Creation Of Arrays Of Pointers To Arrays Of Pointers

Apr 15, 2013

I'm trying to write a function that takes a 32bit address and a data to store at this address.

I'm wanting to take the 32 bit memory address eg 0x12345678 and split it
into 4 x 2 bytes
12, 34, 56, 78

then each of the 4 entries is at most a 256 entry array.eg
FF, FF, FF, FF

So in this example, 0x12 points to 0x34 in the second array, which points to 0x56 in the third array, which finally points to 0x78 in the last array. This last array holds the actual data.

After successfully doing 0x12345678, say I might get a read for 0x1234AABB. So, the first and second pointers already exist, but I then have to create and write to dynamically created arrays.

The arrays need to have all entries set to NULL so that i know whether to follow the pointers to overwrite a previously entered value or create new arrays and pointers.

It all looks good and simple in the pseudo code I've written up but I'm having trouble coding it. I'm currently trying to deal with the first entry case, ie all array elements are NULL, but I'm getting confused with the pointers and creation of new arrays.

void cpu::store(unsigned int mem_add,unsigned int mem_val) {
int first = (mem_address&4278190080)>>24;
int second = (mem_address&16711680)>>16;
int third = (mem_address&65280)>>8;
int fourth= (mem_address&255);

[Code] .....

A1 has been declared as
int* A1[256] ;

Visual C++ :: Retrieving Size Of Each String In Order To Produce A New Buffer For Concatenated String

Feb 25, 2013

What is the efficiency of the two assignments (line 1 and 2), i.e. (function calls, number of copies made, etc), also the Big O notation. I know there are function calls for retrieving the size of each string in order to produce a new buffer for the concatenated string...any difference between line 1 and 2 in terms of efficiency?

String s("Hello");
String t("There");
1. s = s + t;
2. s += t;

C :: Program Where User Inputs A String And Prints Out Length Of String

Jan 29, 2014

I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.

Code:
#include <stdio.h>
#include <string.h>
int main() {
char str[100];
int i = 0;

[Code] ....

Now I understand that it returns the count in "int" so my question is:

Let's say i declared

Code: int count = 0;
at the beginning of the code and then made
Code: count = strlen(str);
why wouldn't i have the same result? Is there a way to do it also?

C++ :: Eliminate Comma And Split String Into Individual String Variables

Nov 15, 2013

I have this string d ="3 J JD, K" and i want to split the string to individual string. I have this code which eliminates the comma but doesn't split the string into individual string.

#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main() {
string str = "3 J JD,K";
stringstream ss(str);

[Code] ....

Output of the code is
3 J JD
k

but I want
3
J
JD
K

Also after I split the string is there any way to put the split string into individual string variables.

C/C++ :: Comparing Input String To Type String Vector

May 29, 2014

I wrote a program that reads a list from a file and stores it in a string type vector. Now, I want the user to input a word so that the program can search the vector to see if that word already exists. I have used every possible way of reading input from the console and storing it in order to compare with the vector but it never results in a match. When I print the input string and the vector string they are exactly the same thing (or at least print to the console as if they were). I've tried using getline; using cin direct to a string var; using cin to a char array and then casting to string using string str(arr); I even added a newline at the end just in case and STILL I cannot get a match.

vector <string> currentSet; //read a list in from a file and has 9 items in it
cin.ignore();
string line;
getline(cin, line);
if(line == vector[0]){//if printed to console line is HEAT and vector[0] is HEAT
cout<<"match"<<endl;
}

C/C++ :: Input Lowercase String / Output Uppercase String

Dec 3, 2014

write a program that prompts the user to input a string and outputs the string in uppercase letters. (Use a character array to store the string.) Does this follow the criteria? This program is very similar to one I found on these forums but I have one problem, it outputs everything backwards! EX: dogs will output to SGOD. What I need to do to make it output correctly, I think it may have to do with getline?

#include <iostream>
#include <cctype>
#include <cstring>
using namespace std;
int main() {
char let[100];
cout << "Enter what you would like to be UPPERCASE: ";

Code:

int main() {
HANDLE clip; // assigns the var. clip to hold a handle ID.

C :: Comparing Of Characters In Given String From Input String?

Feb 7, 2013

I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string

1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)

Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>

[Code]...

2-what is the longest substring of characters strictly rising interm of ASCII code(the following is greater (>) of the previous)

3- what is the longest substring of successive characters interm of given string rannge (i.e.: fhkjshdfruytyzABCDEfglsj => 7)

I'm having lots of trouble with storing a cin string text into a string array. It just seem that after I cin newvalue, the program crashes. Is this way of storing it considered illegal? I'm just a beginner with 5 months of coding experience in C++.
