C++ 最小绝对值

解题思路:

注意事项:

参考代码:

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

int a[10], i = 0, temp, k,min;

for (int i=0;i<10;i++)

cin >> a[i];

min = fabs(a[0]);

for (int i=0;i<10;i++)

{

if (fabs(a[i]) < min)

{

min = fabs(a[i]);

k = i;

}

}

temp = a[k];

a[k] = a[9];

a[9] = temp;

for (auto& r : a)

cout << r << " ";

}
