c语言循环语句打印如下图形： ********A *******BB ******CCC *****DDDD

#include <stdio.h>
int main() {
    int n = 4;
    char c = 'A';
    for (int i = 1; i <= n; i++) {
        for (int j = n; j > i; j--) {
            printf(" ");
        }
        for (int k = 1; k <= i; k++) {
            printf("*");
        }
        printf("%c", c);
        c++;
        printf("\n");
    }
    return 0;
