A no difficulty, pay attention to the beginning of a formula directly counted 5 actually denote by h, there is 2i plus to minus 2, because i starting at 1.

#include<stdio.h>
int main()
{
    int h;
    while(scanf("%d",&h)!=EOF)
    {
        for(int i=1;i<=h;i++)
        {
                int len=2*h-2*i;
                while(len--)
                    printf(" ");
                for(int j=1;j<=h+2*i-2;j++)
                    printf("*");
                printf("\n");
        }
    }
    return 0;
}
