# include main(){ int n=65,s=1,i,j,k,l; for(i=1;i<=6;i++){ printf("%c ",n); n++;} printf("%c ",n); n--; for(j=1;j<=6;j++){ printf("%c ",n); n--;} printf("\n\n"); for(i=6;i>=1;i--){ n=65; for(j=1;j<=i;j++){ printf("%c ",n); n++;} n--; for(k=1;k<=s;k++){ printf(" ");} for(l=1;l<=i;l++){ printf("%c ",n); n--;} s=s+2; printf("\n\n"); }}
