// C program to swap two variables in single line #include <stdio.h> int main() { int x = 5, y = 10; //(x ^= y), (y ^= x), (x ^= y); int c; c = y; y = x; x = c; printf("After Swapping values of x and y are %d %d", x, y); return 0; } ...
执行以上代码输出结果为: 输入x值:1输入y值:2交换后x的值为:2交换后y的值为:1 Python3 实例
Write a Python code snippet to swap the values of two variables without using a temporary variable.相关知识点: 试题来源: 解析 a, b = b, a 在Python中,可以使用元组解包的方式直接交换两个变量的值,无需临时变量。Python的赋值语句右侧会先计算出所有表达式的值,生成一个元组(b, a),然后依次赋值给...
As we can see the codes above, the second method involves a new variables 'temp' while the first method not, so the second method is slower than the first method.
*Write a program to swap the values of two variables.* my Answer m=y n=x x=m y=n *· C**oding Exercise: Shopping* *You are going shopping for meat and milk, but there is tax. You buy $2.00 of milk and $4.00 of meat, and the tax rate is 3%. Print out the total cost...
三、交换变量值(Swap Values) 在其他语言中,交换两个变量值的时候,可以这样写: temp = a a = b b = temp 在Python中,我们可以简单的这样写: b, a = a, b 可能你已经在其他地方见过这种写法,但是你知道Python是如何实现这种语法的吗?首先,逗号(,)是Python中tuple数据结构的语法;上面的语法会执行一下的...
如果playerMoveTo 变量不再设置为 None,那么我们知道玩家打算移动。对 makeMove() 的调用处理了改变 gameStateObj 中玩家位置的 XY 坐标,以及推动任何星星。makeMove() 的返回值存储在 moved 中。如果这个值是 True,那么玩家角色就朝那个方向移动了。如果值是 False,那么玩家一定试图移动到一个墙上,或者推动一个背...
If instead, we were to use Java, the same program would have to be written in the following way: publicclassSwap{publicstaticvoidmain(String[] args){inta,b,temp;a= 15;b= 27;System.out.println("Before swapping : a, b = "+a+", "+ + b);temp=a;a=b;b=temp;System.out.println...
For example, if you wanted to swap two variables, the following looks cleaner than explicitly declaring a temporary variable:a, b = b, a Likewise, if a function returns multiple variables, it's cleaner to say:a, b, c = fun()
When you run this program, the output will look something like this: Enter the name of cat 1 (Or enter nothing to stop.): Zophie Enter the name of cat 2 (Or enter nothing to stop.): Pooka Enter the name of cat 3 (Or enter nothing to stop.): Simon Enter the name of cat 4 (...
