日常C语言小练习-1.0

1. 给定两个整形变量的值,将两个值的内容进行交换。

int i = 1, 
    j = 2, 
    temp = 0;
temp = i;
i = j;
j = temp;
printf("i:%d j:%d", i, j);

2. 不允许创建临时变量,交换两个数的内容

int i = 1,
    j = 2;
i = i + j;
j = i - j;
i = i - j;
printf("i:%d j:%d", i, j);

3.打印10个整数最大值

int num[10] = {6,10,2,4,6,1,8,9,3,5};
	int j,
		max = num[0],
		len = sizeof(num) / sizeof(num[0]);
	for (j = 1; j < len; j++) {
		if (num[j] > max)
			max = num[j];
	}
	printf("这十个整数中的最大数是:%d\n", max);
4.将三个数按从大到小输出。
int a, b, c, temp;
	printf("输入三个数:\n");
	scanf_s("%d %d %d", &a, &b, &c);
	if (a < b) {
		temp = a; a = b; b = temp;
	}
	if (b < c) {
		temp = b; b = c; c = temp;
	}
	if (a < b) {
		temp = a; a = b, b = temp;
	}
	printf("从大到小:%d %d %d\n", a, b, c);

5.求两个数的最大公约数

int x, y, temp;
	printf("请输入两个数\n");
	scanf_s("%d,%d", &x, &y);

	if (x < y) {
		temp = x;
		x = y;
		y = temp;
	}
	for (temp = y; x % temp || y % temp; temp --);

	printf("最大公约数为:%d\n", temp);
