请问如何调用findmax（）函数，寻找数组中的最大元素？

Question

#include<iostream>
using namespace std;
int *findmax(int *array,int size,int *index);
void main()
{
int a[]={33,23,78,99,54,45,76,12,90};
int *maxaddr;
int idx;
maxaddr=findmax(a,sizeof(a)/sizeof(*a),&idx);
cout<<"the index of maximum element is"<<idx<<endl;
cout<<"the address of is"<<maxaddr<<endl;
cout<<"the valve of is"<<a[idx]<<endl;
}

Answer 1

findmax函数只声明，没有实现，

Answer 2

int *findmax(int *array,int size,int *index){ASSERT(index != NULL);int iMax = 0;for(int i = 0; i < size; i++){if(array[i] > iMax){iMax = array[i];*index = i;}}return iMax;}
