Best Pattern Made from Alphabets

#include<stdio.h>/*calling the header files*/
int main()
{
    int i,j,k,n,c,c1=0;  /*initializing the variables which are needed*/
    printf("Please enter the rows for the right and led triangle \n");
    scanf("%d",&n);
    /*Loop for the upper part of the pattern*/
    for(i=n;i>=1;i--)
    {
        c=64;
        for(j=1;j<=i;j++)
        {
            printf("%c",c+j);
            }
        for(k=n;k>i;k--)
        {
            printf("  ");
            }
        c=65+n-c1;
        for(j=1;j<=i;j++)
        {
            printf("%c",c-j);
            }
        c1++;
        printf("\n");
        }
    /*loop for lower part */
    c1=2;
    for(i=2;i<=n;i++)
    {
        c=64;
        for(j=1;j<=i;j++)
        {
            printf("%c",c+j);
            }
        for(k=i;k<n;k++)
        {
            printf("  ");
            }
        c=65+c1;
        for(j=1;j<=i;j++)
        {
            printf("%c",c-j);
            }
        c1++;

When I tried to compile this on my Linux machine, I got the two haves similar to each other. That is, I had the first half repeated, as a doubled left-facing arrow.
