    Storing values in arrays

    Hi, I was wondering if it is possible to store strings in a different array element. for example variable[1] = some_string. If that is possible, I was wondering if you can store any variable in an array? Ok thanks!

    Of course like this?
    Code:
    #include <iostream>
    #include <string>
    
    using namespace std;
    
    int main()
    {
    	string names[] = {"John", "Steve", "Alice"};
    
    	for (int j = 0; j < 3; ++j)
    		cout << names[j] << endl;
    return 0;
    }
    But insteed of using the built in arraymechanism use the STL-component vector.

    I was wondering if you can store any variable in an array
    Only variables of the same datatype.

    char arrayOfStrings[10][20];
    strcpy(arrayOfStrings[0], "Hello");
    strcpy(arrayOfStrings[1], "world");
    strcpy(arrayOfStrings[2], "my name is");
    //etc.

    or a variant to adding string literals

    char word[20] ;
    cout << "enter a word/phrase of less than 20 characters, including any spaces" << endl;
    cin >> word;
    strcpy(arrayOfStrings[8], word);

    those are both character wtrings, for an array:

    Code:
    int numbers[20];
    //all values in array 'numbers' are of int type, and the maximum capacity of the array is 20
    
    numbers[1] = 1;
    numbers[2] = 2;
    //this method gets dull, try something like this
    int i =3;
    while (i < 20) {
    numbers[i] = i;
    i++;
    }
    i = 0;
    //lets output it all
    while (i < 20) {
    i++;
    cout << numbers[i] <<"\n";
    multi-valent arrays (I believe thats the correct term) look like this:
    int mvarray[1][2];
