一、c语言嵌套循环类型

---

for(初始值；表达式；表达式)
{
	for（初始值；表达式；表达式）
	{
	代码
	}
}

---

int main()
{
	for (int i = 0; i < 5; i++)
	{
		for (int j = 0; j < 5; j++)
			printf("%d\t%d\n", i, j);
	}
}

二、嵌套循环案例九九惩罚口诀

---

int main()
{
	for (int i = 1; i < 10; i++)
	{
		for (int j = 1; j <= i; j++)
		{
			printf("%d*%d=%d", i, j, i * j);
		}
		printf("\n");
	}
}
