How do you assign values to elements in an array in c? - c

Question

I've tried two-dimensional arrays, varying prototype functions, and I can't seem to implement a score system for this game. Any ideas on what I can do? I want to take the output from this code, which are 6 varying numbers from 1-6, and assign them a value that I can add up to make a score. Ex. If I roll a 1, it would be worth 100 points. What's the quickest and most efficient way to assign a point value to the rolled value?
#include <stdio.h>
#include <time.h>
int main() {
int i, r, diceRoll;
char player1[20];
int temp, swapped;
int roll1[6];
srand(time(NULL));
printf("Enter name for Player 1:\n");
scanf(" %s", &player1);
for(i = 0; i < 6; i ++) {
r = ( rand() % 6 ) + 1;
diceRoll= r;
roll1[i] = diceRoll;
}
while(1) {
swapped = 0;
for( i = 0; i < 6-1; i++ ) {
if( roll1[i] > roll1[i + 1] ) {
temp = roll1[i];
roll1[i ] = roll1[i+1];
roll1[i+1] = temp;
swapped = 1;
}
}//for
if( swapped == 0) {
break;
}
}//while
printf("\n\n %s's Dice Roll:\n\n", player1); // prints out the dice rolls of player 1
return 0;
}//main

Why not do a straight aggregation of the values mapped to the corresponding point value? (Unless it is straight 100 * the roll value, in which case it is even easier.)
int score = 0;
for( i = 0; i < 6; ++i )
{
switch( roll1[i] )
{
case 1: score += 100; break;
case 2: score += 230; break;
case 3: score += 540; break;
case 4: score += 2320; break;
case 5: score += 13130; break;
case 6: score += 454260; break; /* Of course, change to the score you want for each value. */
}
}
printf("\n\n %s's Dice Roll:%d\n\n", player1, score);
"What I originally had in mind was to make the game like Farkle, where 1 is 100pts, 5 is 50pts, and everything else is 0 until you get 3 of a kind ( Three 3s = 300pts, Three 1s is 1000, etc). Any input would be greatly appreciated" There are many ways. You can do this easily and use Chux map approach for base and three of a kinds.
int score = 0;
int face_score = 0;
int base_points[6] = { 100, 0, 0, 0, 50, 0 };
int three_of_a_kind_points[6] = { 300, 200, 300, 400, 500, 600 };
int four_of_a_kind_points[6] = {
int repeat_counter[6] = { 0, 0, 0, 0, 0, 0 };
int kind_mask = 0;
int pair_count = 0;
int three_of_a_kind_count = 0;
int four_of_a_kind_count = 0;
for( i = 0; i < 6; ++i )
{
kind_mask |= 1 << ( roll1[i] - 1 );
switch( ++repeat_counter[roll1[i] - 1] )
{
case 1: break;
case 2: ++pair_count; break;
case 3: score = three_of_a_kind_points[rolli[i] - 1]; ++three_of_a_kind_count; break;
case 4: score = 1000; ++four_of_a_kind_count; break;
case 5: score = 2000; break;
case 6: score = 3000; break;
}
}
if( pair_count == 3 ) /* Three pairs */
score = 1500;
else if( three_of_a_kind_count == 2 ) /* Two three of a kinds */
score = 2500;
else if( four_of_a_kind && ( pair_count == 2 ) ) /* A four of a kind and one pair (2 because four of a kind counted as a pair in the aggregation phase) */
score = 1500;
else if( kind_mask = 0x2F ) /* One of each type */
score = 1500; /* Straight */
else if( !score ) /* score only 1's and 5's */
score = repeat_counter[0] * 100 + repeat_counter[4] * 50;
printf("\n\n %s's Dice Roll:%d\n\n", player1, score);
I have not compiled or run this code, so it may not be 100% correct.
