使用指针拷贝数组

int arrayCopy(char *from,char * to){//不要轻易改变形参的值，引用辅助指针变量，把形参接过来；char *myfrom=from;char *myto=to;if(from==NULL||to==NULL)//if语句增强程序健壮性{return -1;}while(*myto=*myfrom){myfrom++;myto++;}}int main(){char from[]="COPY ARRAY";char myArray[100];arrayCopy(from,myArray);printf("%s\n",myArray);system("pause");return;}
