#include <stdio.h>int main(){//整數(shù)按從小到大排列,不破壞原數(shù)值void swap(int *p1,int *p2); //申明swap函數(shù)int a,b;??????????????????? //定義初始變量int *pointer_1,*pointer_2;? //定義兩個(gè)指針變量printf("please enter a and b:\n");scanf("%d,%d",&a,&b);?????? //將輸入的兩個(gè)常數(shù)賦值給初試變量a ,bpointer_1 = &a;pointer_2 = &b;if (a>b)swap(pointer_1,pointer_2);printf("min = %d,max = %d\n",b,a);printf("max = %d,min = %d",*pointer_1,*pointer_2);return 0;}void swap(int *p1,int *p2){?int p;?p = *p1;?*p1 =*p2;?*p2 = p;}
為什么a,b使用指針交換值編譯通過(guò)，但出現(xiàn)異常值？（什么先輸出大先輸出小就別管了，懶得改）
