C :: Can Strings Fit In Array

Mar 5, 2013

1. I finished reading a beginning C book, and in the section about arrays, it says that one string can fit in a character array (char arrayname[]) but there cannot be a string array (string arrayname[]) that have multiple strings. Is

Code: string arrayname[4] = {"one", "two", "three"}; not valid?

My compiler lets me run it and it works, but why is the book saying it's wrong?

2. I know you can represent multiple strings in a character array by:

Code: char newarray[10][4] = ("one", "two", "three");

because [10][4] indicates that there should be four newarrays created with a max of 10 characters each, but is

Code: string multiplestrings[10][4] = ("i love you", "hello come to me", "i don't get C"; "hello world", "what are arrays"; "i am happy", "I am learning how to code"); valid?

Does multiplestrings[10][4] basically create 4 string arrays that have a maximum of 10 different strings within each string array?

C :: Array Of Pointers To Strings

Mar 6, 2015

I'm wondering how to access Buffer 1 and 2 via the pointer array;

Code:
char *BufPtrs[3];
char Buffer1[64];
char Buffer2[64];
BufPtrs[0] = Buffer1;
BufPtrs[1] = Buffer2;
BufPtrs[2] = NULL;

I thought that if I were to access Buffer1 via BufPtrs[0], I would simply just put an * to it before printf()-ing or store it in a char[] (equivalent to a string).

I am having trouble storing strings into an array. Basically I have a console program where it has an option. This is just an example;

And how can I print it?

C/C++ :: How To Input Strings Into 3D Array

Feb 19, 2014

I was very much confused with managing the 3d arrays. Other than initialising it is tough for me to input the data into the 3d array at runtime. I have tried the every possible method i know untill now but i can't successfully input and output the data.

I have written a code by declaring the 3d array of char s[5][2][20] in main and passing it's base address into another function, lets say input(char (*p)[2][20],int ,int ,int). I have passed the 3 dimensions in declaration 5,2,20 to the input function i have used these 3 values as the subscript for the pointer p and tried to input the data. But i wasn't successful.

How to input the strings into the 3d array.

My preferences were:

1.The change of subscript value should take place in loop(eg:for).
2.Which indexes should be used for inputing the data through pointer.
3.Use either "scanf" or "gets" function to inputs the data and print using "printf" or puts.

C :: How To Convert From Array Of Chars To Strings

Jan 13, 2014

As a part of a program I am supposed to write, I would like to receive a string from the user (for example: "Hi my name is Joe").

obviously, the string is inserted to an array of chars (arr[0]='H', arr[1]='i', arr[2]=' ',... and so on).

What I would like to do, is to put each word separately in each array cell (for example arr[0]='Hi', arr[1]="my"..., and so on). How can I do this? (I can not use any functions, unless I write them myself).

C++ :: Dynamically Allocate Array Of Strings

Jul 26, 2014

I know I can allocate it this way, on the stack:

char* str[5];
for(i = 0; i < 5; ++i) {
str[i] = new char[STR_SIZE];
}

But if I want to allocate array size through 'new', what's the syntax for that?

I thought this might work, but it gives error: "Initialization with {...} expected for aggregate object"

char* newString[] = new char[5][ARRAYSIZE];

C# :: Randomly Select Strings From Array

Mar 27, 2014

I am trying to select 3 questions randomly from a string array and create another array with the randomly selected questions then display them in labels.

As you can see in the code I have used Array.Clear method to remove the selected question from the array to prevent duplicate questions being selected. For some reason this is not working! The "Randomly" selected question is ALWAYS the 5th element [4] of the randomQuestions array and this element is duplicated for each iteration of the loop.

public void shuffleQuestions() {
string questionselected;
string[] randomQuestions = {
"What is the speed limit from the time you pass an Accident sign until you have passed the crash site?",
"What must you do at a red traffic light?",
"What is the maximum possible speed limit on the open road?",

C :: Concatenate Strings In Array (2D) - Function Not Working Right?

I have a function that concatenate the strings in an array(2D)

The concatenation function working correctly and displays correctly in the function. But if I make another function to display it, it shows this

It adds to first name. Why?

C :: Combinations - Putting Strings Into Array From A File

Apr 4, 2014

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];

[Code] .....

What I am trying to get working right now is just to scan a file and put the strings into an array so then I can work on sorting the array. How can I add strings from a file into an array?

C/C++ :: Reading Strings To Char Array From Exe File

Feb 25, 2014

I am trying to read strings to an char array from an .exe file and then i would check some of the strings, but the problem is that the only thing that is read from the file is the first string (MZ) and an 'square' that is some incorrect character. I am using fread to read from the file. Here is my code:

FILE * pFile;
long lSize;
char * buffer;
size_t result;
pFile = fopen("my_file.exe", "rb");
if( pFile == NULL) exit(1);
fseek(pFile,0, SEEK_END);

C# :: How To Match Regex If Input Was Array Of Strings

May 19, 2014

In the MSDN, it gives an example using Regex.Matches method:

using System;
using System.Text.RegularExpressions;
public class Example {
public static void Main() {
string pattern = "a*";
string input = "abaabb";
foreach (Match m in Regex.Matches(input, pattern))
Console.WriteLine("'{0}' found at index {1}.",
m.Value, m.Index);

[code]......

I am wondering if string input was an array of strings instead, how would I use Regex.Matches?

What I was thinking about doing is having the input array set to ToString(), input.ToString(), but that doesn't seem to work.
