你说的是那道题？是编译错误么

by zhangcnmua @ 2024-07-18 16:38:40

@wky_wsy 建议用cin输入和cout输出

@wky_wsy

1. l%r 不需要 -1

2. while 循环中你没有 i++

#include <bits/stdc++.h>
using namespace std;
char z[10000000]="";
string m="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
int r,n,l,i=0;
int main(){
    scanf("%d%d",&n,&r);
    l=n;
    while(l){
        z[i]=m[l%r];
        l/=r;++i;
    }
    int L=strlen(z);
    for(int i=L-1;i>-1;i--){
        printf("%c",z[i]);
    }
    return 0;
}

@wky_wsy你试一试这个代码 ```cpp

• include <bits/stdc++.h>

• std::string dec_to_base(int N, int R) - {

  • const std::string digits = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

  • std::string result;

  • do {

    • result = digits[N % R] + result;
    • N /= R;

  • } - while (N > 0);

  • return result; }

• int main() {

  • int N, R;
  • std::cin >> N >> R;
  • std::cout << dec_to_base(N, R) << std::endl;
  • return 0;

• }
