Randomize (please help

Hi guys

I am new to programming and need help. I need to create a quiz using random in C++. I have 2 arrays of the same words in the same order in 2 languages. I would like to write a piece of code that picks a word at random from one of the arrays and askes for the equivelent word from the other array. I would need a loop of some kind to give the user so many attemps. What header file do I need to use for random? Any help would be great.

Thanks in advance

edit:

When you says two arrays of words, are you talking about a string of words separated by spaces like

Code:

---

EnglishWord1 EnglishWord2 EnglishWord3

---

or something similar? If so, I would rethink your design. It'd be much easier to have an array of char pointers and set those equal to string constants (or the addresses of other strings if the strings are supplied by file or other method at run time).

to get random numbers use the rand() function

to control how many attempts the user gets use a loop (most likely a for loop)

instead of using arrays i would use a vector:

Sorry, here is more info.

Code:

---

#include "stdafx.h"
#include <iostream>
using namespace std;
 
 char engwords [50][12] = {"Dog","Cat","Computer","Chair","Love","School",
 "Talk","Word","Letter","Jump","Pencil","Paper","Coffee",
 "Milk","Bag","Board","Eraser","Wound","Morning","Night","Noon",
 "Dinner","Skin","Green","Blue","Red","Earthequake","Volcano","River",
"Sea","Trousers","Joy","Happy","Stairway","Vegetables","Cup","Scissor","Shoes","Can","Car","Job","Work",
"Boy","Girl","Soil","Baby","Leader","Shout","Write","Hand"};//the array of 50 english words


char philwords [50][12]= {"Aso","Pusa","Kompyuter","Silya","Mahal","Paaralan","Usap","Salita",
"Letra","Lukso","Lapis","Papel","Kape","Gatas","Bag","Pisara","Pambura","Sugat","Umaga",
"Gabi","Tangali","Hampunan","Balat","Berde","Asul","Pula","Lindol","Bulkan","Ilog","Dagat",
"Pantaloon","Ligaya","Maligaya","Hagdanan","Gulay","Tasa","Gunting","Sapatos","Lata","Kotse",
"Trabaho","Gawa","Lalake","Babae","Lupa","Bata","Pinuno","Sigaw","Sulat","Kamag"};//the array of 50 philippine words



char option;
int translator();
int quiz();
int main()
{

i want the programme to randomley pick an english word from the english array and ask for the philopine translation. possibly giving the user 3 chances to get it right.

If your array has 50 entries, simply use the links posted above for how to get a random number between 0 and 49 (inclusive). That will randomly pick an english word from your array.

To ask for a translation might be more difficult, since you would have to search your Tagalog array for the string the user enters. One easier option is to list all the words in the tagalog array with a number (like 1 - 50: the array index + 1) and have the user pick the number of the matching word. If the number they pick matches the random number + 1, it is correct. The +1 is because array offsets start at 0 but users usually will think starting from 1.

Maybe use a map<int,pair<string,string> > container? As a demonstration of how it could be setup and the data within accessed:

Code:

---

map<int,pair<string,string> > dictionary;


// Insert English/Tagalog strings into the map container
dictionary.insert(make_pair(0,make_pair(string("Dog"),string("Aso"))));
dictionary.insert(make_pair(1,make_pair(string("Cat"),string("Pusa"))));
dictionary.insert(make_pair(2,make_pair(string("Computer"),string("Kompyuter"))));
dictionary.insert(make_pair(3,make_pair(string("Chair"),string("Silya"))));
...

// Pick a random index
int indx = rand() % dictionary.size();

// Show English/Tagalog side-by-side
cout << "The Tagalog translation of the English word \"" << dictionary[indx].first
    << "\" is \"" << dictionary[indx].second << "\"." << endl;

---

Possible output:

Code:

---

The Tagalog translation of the English word "Chair" is "Silya".

---

The setup of the map could be made easier if the English/Tagalog words were read in from a file. Then you wouldn't need some huge set of insert statements, you'd just have a loop that reads through a file. You should be able to take the above a modify it to print out the English word stored in the map, ask the user for the translation, and then compare what the user entered with the translation that is also stored in the map.

Many thanks for you help
