Thread: cannot understand this output - atoi

Code:

#include<stdio.h>
#include<conio.h>
#include<string.h>
#include<stdlib.h>

int main(void)
{
        char arr[50],a;
        char *ar;
        int x;
        
        printf("GETS --> ");
        ar = gets(arr);

        printf("PUTS --> ");
        puts(arr);

        sscanf(arr,"%c",&a);
        printf("PRINTF --> ");
        printf("%c\n",a);

        printf("ATOI --> ");
        x = (int) atoi(&a);
        printf("%d\n",x);

        getch();
}

OUTPUT

GETS --> 2
PUTS --> 2
PRINTF --> 2
ATOI --> 22 ? It should be 2
