c_cpp 将全零移动到数组的末尾

Posted 2021-05-14

#include <iostream>
using namespace std;

int main(){
    int n;
    cout << "No.of elements:";
    cin >> n;
    int a[n];
    cout << "Enter the elements:\n";
    for (int i = 0; i < n;i++)
        cin >> a[i];
    int count = 0;
    for (int i = 0; i < n;i++)
        if (a[i] != 0)
            a[count++] = a[i];
    for(int i=count; i < n; i++)
        a[i] = 0;

    for (int i = 0; i < n;i++)
        cout << a[i] << "  ";
}
