One dimensional Array_1.2

#include <stdio.h>
int main(void)
{
    int i,a[100];
    char k='A';
    for(i=1;i<=26;i++)
    {
       a[i]=k;
       k++;
    }
    
    for(i=1;i<=26;i++)
    {
       printf("%2c",a[i]);
    }
    printf("\n");
    system("pause");
    return 0;
}

This is the output:
