C++的简单问题

#include <iostream>

using namespace std;

int main()
{
const int N = 5;
int num[N];

cout << "请输入五个整数--> ";
cin >> num[0];
int min, max;
min = max = num[0];

for (int i = 1; i < N; i++)
{
cin >> num[i];
if (num[i] > max)
{
max = num[i];
}
if (num[i] < min)
{
min = num[i];
}
}

cout << "max = " << max << endl;
cout << "min = " << min << endl;

system("Pause");
return 0;
}

用2个FOR就可以.
#include <stdio.h>
void main()
{
int i,j,temp;
int a[]={54,65,78,98,55};
for(i=0;i<5;i++)
{
for(j=0;j<i;j++)
{
if(a[j]>a[j+1])
