Output single character in C
4 answers
I'm trying to code a simple fruit slot machine, where it outputs 3 random values and then if there are two or more matching values, then the user "wins".
The problem I have is that when I output the 3 reels, when I set the values of the array to letters, it outputs numbers such as 99, which I presume are ASCII values of the letters.
Below is the code I currently have:
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
int main()
{
srand (time(NULL));
int i;
int reels;
char images[4] = {'b', 'o', 'c', 'h'};
for (int reels = 1; reels < 4; reels++)
{
int reelNumber = rand() % 4;
int reelValue = images[reelNumber];
printf("And the winnings for reel %d is: %dn", reels, reelValue);
}
return 0;
}
All help is appreciated,
Thanks.

In the printf function your using the %d substitution for reelValue and %d is for decimal types; if you use %c instead the program will print the character instead of the number.

The array is accessed starting at 0. What is starting at 1 is the number of the reel which ist not used to access an array. No risk of out of bounds accesses.

Ah, yes you're correct the modulus 4 takes care of it.
