哪个z（）函数是用来转进制的

if(x<=9&&x>=0) return x+48; else return x+55;

#include<bits/stdc++.h>
using namespace std;
int n,r,cnt;
char a[1000001];
int main(){
    cin>>n>>r;
    while(n!=0){
        cnt++;
        if(n%r>=10)a[cnt]='A'+n%r-10;
        else a[cnt]=n%r+'0';
        n/=r;
    }
    for(int i=cnt;i>=1;i--)cout<<a[i];

}

这样更直观一点
