你题目的解答代码如下：

#include<stdio.h>
int main()
{
    for (int i = 0; i < 4; i++)
    {
        for (int j = 0; j < 3-i; j++)
            printf(" ");
        for (int j = 0; j < 2*i+1; j++)
            printf("%c", i+'a');
        printf("\n");
    }

    for (int i = 2; i >= 0; i--)
    {
        for (int j = 0; j < 3-i; j++)
            printf(" ");
        for (int j = 0; j < 2*i+1; j++)
            printf("%c", i+'a');
        printf("\n");
    }

    return 0;
}
