I have a 2D array with 108 strings. How do I shuffle it correctly?
Code:
void Shuffle( char dest[208][13] )
{
// Initialize variables
char temp[13];
// Loop and shuffle(swap array values)
[Code] .....
The program force closes.
Is there member functions for STL's like vector,list etc., to shuffle the content of that STL.
eg:
int arr[] = {1,2,3,4};
std::vector<int> v1(arr, arr+ sizeof(arr) / sizeof(int) );
now i need to shuffle the data randomly like
Now vector may contain {3,2,4,1} or {2,1,4,3} ...
I have taken vector as an example. let me know if there is any alternative way with other STL's
I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.
void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';
} for(int a = 0; a <= numCards; a++) {
cout >> showCard(cards[a]);
} }
I'm trying to make a calendar and I don't know how to cin strings into an array's index inside a function.
This is my current program.
Code:
#include<iostream>
#include<string>
using namespace std;
void viewMonth (string month[], int num);
void dayNote (string month[]);
int main()
[Code].....
I have a function that concatenate the strings in an array(2D)
Ex 1: Sean Connery Micheal King James Wood
Result: SeanConnery MichealKing JamesWood ...
The concatenation function working correctly and displays correctly in the function. But if I make another function to display it, it shows this
Ex 2: SeanConnery Sean MichealKing Micheal JamesWood James..
It adds to first name. Why?
Code:
void Concatenation( char dest[200][13] ) {
// loop through and concatenation the strings
for(int i=0;i<200;i+=2) {
myStrCat(dest[i],dest[i+1]); // mystrcat is equalto strcat()

I am trying to write a sub-program that takes a deck of 52 cards and will shuffle it up using this algorithm:
Start with n=51
Repeatedly:
Generate a random integer between 0 and n. Call it i.
Swap card i and card n in the deck.
Decrease n by 1
However the code that I've written,
vector<int> shuffleDeck(vector<int> deckVector)//deckVector is the original deck in order
{
int temp, n, i, s;
n = 51;
[Code].....
when I output the new vector, only produces this output(note- it is a random number every time, but it just repeats over and over):
8 8 8 8 8 8 8 8 0 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8
8 8 8 8 8 8 8 8 8 8 8 8
or:
22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 0 22 22 22 22

What's wrong with my shuffle function? It shuffles some songs, yet completely gets rid of others.
Here's the code:
void shuffle() //Shuffles songs into a random order. {
Music temp, temp2; //Temporary music file holders, 'Music' is a struct with string title;, string artist;, and int size;.
unsigned int currentTime = (unsigned)time(0);
srand(currentTime);

I want it to output this:
1. Title: Runaway2, Artist: Bon Jovi2, 2 MB
2. Title: Runaway5, Artist: Bon Jovi5, 5 MB
3. Title: Runaway1, Artist: Bon Jovi1, 2 MB
4. Title: Runaway4, Artist: Bon Jovi4, 1 MB
5. Title: Runaway7, Artist: Bon Jovi7, 5 MB
6. Title: Runaway6, Artist: Bon Jovi6, 5 MB
7. Title: Runaway3, Artist: Bon Jovi3, 5 MB
8. Title: Runaway8, Artist: Bon Jovi8, 1 MB
Or something along those lines, but instead I get something like this:
1. Title: Runaway7, Artist: Bon Jovi7, 1 MB
2. Title: Runaway2, Artist: Bon Jovi2, 2 MB
3. Title: Empty, Artist: Empty, 1856312448 MB
4. Title: Runaway4, Artist: Bon Jovi4, 1 MB
5. Title: Runaway5, Artist: Bon Jovi5, 5 MB
6. Title: Empty, Artist: Empty, 0 MB
7. Title: Runaway7, Artist: Bon Jovi7, 1 MB
8. Title: Empty, Artist: Empty, 1856312448 MB
I learned the bitwise operations in c, but how to shuffle the bits of the plain text accoring to DES's standard. Even with the key and the S-boxes. How DES is performed in C step by step. I have a fair knowledge in C.

I am writing a driver program that will eventually need to pass two strings to a function I am writing in a separate file. I am reading data from a file that is formatted like this:
ac: and
amo: love

Only a few of the words are actually being processed in the way I want. It appears that only words followed by a comma are processed correctly.
I made my own function to search if two given strings in my function are equal but the problem is if i pass two variable like hello,hello ... result is string equal but if i pass hello , hello also give me string equal because last 4 characters same to last 4 characters of hello ...

int getSimilarityOfTwoStrings(const char str1[],const char str2[]){
int str1Len = getStringLength(str1);
int str2Len = getStringLength(str2);

dont need to write the string encrypted and dont need to crate a decrypt function.
The following code fails/crashes in the second loop where it prints the content and frees the memory. But the issue could be with the first loop.

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?
My code so far
Code:
#include <stdio.h>
#include <ctype.h>
#include <string.h>

I have the following function I would like to convert to work with std:string. I don't understand QT strings at all.
Code:
void FromHexString(const QString &hexText, void* pData, int dataSize) {
for (int i = 0; i < hexText.length(); ++i) {
bool ok = false;
((uint8_t*)pData)[ i ] = hexText.mid( 2*i, 2 ).toInt( &ok, 16 );
}

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;
Code:
char name[max];
char listofnames[maxname];
int counter;
....
printf("Add names
");
And how can I print it?
I am having this problem were the user types in a substring to search in the main string and replace it with another string
for example:
string: hello
sub string: el
replace: i
should print this: hillo
I tried using some string functions but I am having problems with that.
How do you use a for loop to iterate through strings to display them in a console?

i have been trying to do a function that unites strings entered by user, i need to do this without any other libraries but i keep getting an output of the first word and dots.
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.
I am creating a doubly linked list that will store strings, for example:
struct node{
string data;
node* next;
node* prev;
};
node* head; //first element from left to right (global)
node* tail; // last element from left to right (global)
And here is the function:
void deleteNode(int n){
struct node* temp1 = head;
if (n == 1){
head = temp1->next;
free(temp1);

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).
