c++进制转换，函数调用

Question

Answer 1

你题目的解答代码如下：

#include<iostream>
using namespace std;

void DecToBin(int n, char b[])
{
    int i, t = 0;
    int v;
    do
    {
        v = n % 2;
        b[t] = v + '0';
        n = n / 2;
        t++;
    } while (n > 0);
    for (i = 0; i < t / 2; i++)
    {
        v = b[i];
        b[i] = b[t - 1 - i];
        b[t - 1 - i] = v;
    };
    b[t] = '\0';
}
int main()
{
    int n;
    char b[500];
    cin >> n;
    DecToBin(n, b);
    cout << b << endl;
    return 0;
}
