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;
}
