c语言怎样交换两个数组 用swap函数

Answer 1

void swap_array(int *pa,int *pb);

main(){
int x[]={0,1,2,3,4};
int y[]={5,6,7,8,9};
swap_array(x,y);
int i;
for(i=0;i<5;i++)
printf("%d",x[i]);
printf("\r\n",x[i]);
for(i=0;i<5;i++)
printf("%d",y[i]);
scanf("%d",&i);
}
void swap_array(int *pa,int *pb){
int n;
n= sizeof(pa);
int c;
int i;
for(i=0;i<=n;i++){
c=*pa;
*pa=*pb;
*pb=c;
++pa;
++pb;}
}
