My scrabble program gets broken when I put numbers into it.
#include <ctype.h>
#include <cs50.h>
#include <stdio.h>
#include <string.h>
// Points assigned to each letter of the alphabet
int POINTS[] = {1, 3, 3, 2, 1, 4, 2, 4, 1, 8, 5, 1, 3, 1, 1, 3, 10, 1, 1, 1, 1, 4, 4, 8, 4, 10};
int compute_score(string word1);
int main(void)
{
// Get input words from both players
string word1 = get_string("Player 1: ");
string word2 = get_string("Player 2: ");
// Score both words
int score1 = compute_score(word1);
int score2 = compute_score(word2);
if(score1>score2)
printf("Player 1 wins!");
else if(score1<score2)
printf("Player 2 wins!");
else
printf("Tie!");
// TODO: Print the winner
}
int compute_score(string word)
{
// TODO: Compute and return score for string
int sum = 0;
for(int i = 0, n = strlen(word); i < n; i++)
sum = sum + (POINTS[(int)(toupper(word[i]))- 65]);
return sum;
}
How can I screen out any sort of number input, or negate it so a user can't enter numbers whatsoever to the string?
I'd be particularly interested in learning how I could reject any values within the compute_score function that aren't 0-25 (Values that fall outside of my array length).
Thanks for the help!
