#include <stdio.h>                                      *                     
int main()                                             ***
{                                                     *****
    int i,t,m;                                       *******           
   
    for(i=1;i<=4;i++)
    {
        for(t=i;t<=4;t++)                                            
        {
            printf(" ");
        }
        for(m=1;m<=i*2-1;m++)
        {
            printf("*");
        }
        printf("\n");

        

    }
   
}

但是如何使用for或while把这个三角写出来

把for(i=1;i<=4;i++)
改成for(i=4;i>=1;i--)
看看

谢谢~！已经过关了~！
