数组初始化

---

---

方法一

---

int main()
{	//像变量赋值一样，为数组的元素一次赋值
	int socres[5] = { 99,89,78,67,78 };
	for (int i = 0; i < 5; i++)
	{
		printf("%d\n", socres[i]);
	}
}

---

方法二

int main()
	//赋值时为数组前面元素赋值，如果数组长度超过赋值元素个数，后面元素依次默认赋值为0
{	int socres[5] = { 99,89 };
	printf("数组长度：%d\n", sizeof(socres) / sizeof(socres[0]));
	for (int i = 0; i < sizeof(socres) / sizeof(socres[0]; i++)
	{
		printf("%d\n", socres[i]);
	}
}

---

方法三

int main()
{	int socres[] = { 99,89,78 };
	printf("数组长度：%d\n", sizeof(socres) / sizeof(socres[0]));
	for (int i = 0; i < sizeof(socres) / sizeof(socres[0]); i++)
	{
		printf("%d\n", socres[i]);
	}
}

---

方法四

int main()
	//给数组赋值全为0
{	int socres[3] = { 0 };
	printf("数组长度：%d\n", sizeof(socres) / sizeof(socres[0]));
	for (int i = 0; i < sizeof(socres) / sizeof(socres[0]); i++)
	{
		printf("%d\n", socres[i]);
	}
}
