进制转换

输入一个十进制数

输出将进制转换为素数之后的十进制的值

例： 输入十进制111，再输入三个进制2,3,5，输出为37.

 

#include<stdlib.h>
int transNum(int* toNum, int fromNum){
	int temp;
	int count = 0;
	int sum = 0;
	while(fromNum){
		temp = fromNum % 10;
		if(toNum[count] <= temp){
			return -1;
		}
		if(count == 0){
			sum += temp;
		}
		else
		{
			int i = count;
			for(;i >= 0; i--)
			{
				temp = toNum[i] * temp;
				
			}
			sum += temp;
		}
		fromNum = fromNum / 10;
		count++;
	}
	return sum;
}

int main(){
	int fromNum = 222;
	int toNum[] = {2,3,5,6,7};
	int result = transNum(toNum, fromNum);
	printf("%d" ,result);
	getchar();
