Switch statement into an array.

[johnnydiamond08]

Hello, I'm trying to store the count of each roll into an array to simplify the code. However, I'm fairly new to C++ programming and could use some help. I have commented out some ideas I have that just don't work. All input is greatly appreciated thank you!

const int FACES    = 6;    //faces of a standard die
const int LOW_FACE = 1;    //lowest face on a standard die

//function header
int roll2Dice(void);
int roll(void);

int main ()
{
    const int NUM_ROLLS = 120000;    //number of rolls

    //variable declaration
    int num2  = 0;   //number of faces with 2
    int num3  = 0;   //number of faces with 3
    int num4  = 0;   //number of faces with 4
    int num5  = 0;   //number of faces with 5
    int num6  = 0;   //number of faces with 6
    int num7  = 0;   //number of faces with 7
    int num8  = 0;   //number of faces with 8
    int num9  = 0;   //number of faces with 9
    int num10 = 0;   //number of faces with 10
    int num11 = 0;   //number of faces with 11
    int num12 = 0;   //number of faces with 12
    int toss  = 0;   //roll of 2 dice
    int seed;        //seed for random number generator

    for (int cnt=1; cnt <= NUM_ROLLS; cnt++)
    {

        toss = roll2Dice( );

Do it so,

int num[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};

        switch (toss)
        {
            case 2:
                num[2]++;
                break;

That should work.

Do I encase every num in the array?

Actually I just realized I'm supposed to store each roll into an array. I'm not sure how they are suppose to connect in the code, and I'm very confused by this idea. I understand all the fundamentals just not how they mesh.
Ex:

int num[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};

        switch (toss)
        {
            case 2:
                num[2]++;
                break;
           case 3:
                num[3]++;
                break;

use this for variable declaration. SO much easier it gives an array of 6 characters and setts them all to 0.

void setting(int faces[], int &toss, int &seed)
{
	int i;
	for(i=0; i<highest; i++)
	{
		faces[i]=0;
	}
	toss=0;
	seed=0;
}

void main()
{
int faces[highest];
int toss, seed, i;

//sets All faces to zero
setting(faces, toss, seed);



system("pause");
}
