如何输出此图案。希望大神们可以写清楚注释

Answer 1

for (int i = 0; i < 7; i++)///方法:按空格个数的规律和数字的规律分别计算

{

if (i<4)

{

for (int m = 0; m < 3- i; m++)

printf(" ");

for (int k = 0; k < 2 * i + 1; k++)

printf("*");

printf("\n");

}

else

{

for (int m = 0; m < i-3; m++)

printf(" ");

for (int k = 0; k < 7-(i-3)*2;k++)

printf("*");

printf("\n");

}

}
