代码题 10进制转任意进制

#include<iostream>
using namespace std;
void convert(int n,int base,char a[]){
	int i=0;
	while(n>0){
		if(base<10||n%base<10){
			a[i++]=n%base+'0';//填空
			}
		else{
			a[i++]=n%base+'A'-10;//填空
		}		
		n=n/base;	
	}
	a[i]='\0';
} 
void print(char a[]){
	int i=0,j=0,temp=0;
	while(a[j])j++;
	j=j-1;//填空
	for(;i<j;i++,j--){//填空
		temp=a[i];
		a[i]=a[j];
		a[j]=temp;
	}
	cout<<"结果："<<a;
}

int main(){
	int number,base;
	char a[20];
	cin>>number>>base;
	convert(number,base,a);//填空
	print(a);
	return 0;
}
