Swap的简单实现 //C语言方式(by-pointer): template <typename Type> bool swapByPointer(Type *pointer1, Type *pointer2) { //确保两个指针不会指向同一个对象 if (pointer1 == NULL || pointer2 == NULL) { return false; } if (pointer1 != pointer2) { Type tmp = *pointer1; *pointer1 ...

swap函数一般是一个程序员自定义函数。通常是实现两个变量数值的交换,用法比较广泛。可使用临时变量实现交换；可通过临时指针变量实现交换；可借助指针加入临时变量来实现交换。return 0;} swap1: x:4,y:3 swap2: x:4,y:3 swap3: x:3,y:4 swap4: x:4,y:3 swap5: x:3,y:4 swap6: x...

先前我们说了C语言中整型变量的形式参数传递的是值而不是地址,那么现在我们就让它传递地址,直接交换实际参数的值。 #include <stdio.h> void swap(int *x,int *y)//使用指针传递地址 { int temp; temp=*x; *x=*y; *y=temp; } int main() ...
