程序填空,使得输出结果为:
1,4,9,16,25,
h,e,l,l,o,!, -
#include <iostream> using namespace std; void ForEach(void * a, int width, int num,
// 在此处补充你的代码
-
) { for(int i = 0;i < num; ++i) f((char*)a+width*i); } void PrintSquare(void * p) { int * q = (int*)p; int n = *q; cout << n * n << ","; } void PrintChar(void * p) { char * q = (char*)p; cout << *q << ","; } int main() { int a[5] = {1,2,3,4,5}; char s[] = "hello!"; ForEach(a,sizeof(int),5,PrintSquare); cout << endl; ForEach(s,sizeof(char),6,PrintChar); return 0; }
