Question

求改错：用C语言把任意进制转化成十进制的算法，检验二进制的有时候有问题。代码如下。看project1就可以

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

void project1();
void project2();

int x;
int y;
int a;
int b;

int main(int argc, char *argv[])
{
printf("1.十进制转化为任意进制；\n");
printf("2.任意进制转化成十进制；\n");
printf("3.退出\n");
while(x!=3)
{
printf("请选择服务序号：\n");
scanf("%d",&x);
if(x==1)
project1();
else if(x==2)
project2();
else if(x==3)
break;
else
printf("输入不符合规范，请重新输入\n");
}
system("PAUSE");
return 0;
}

void project1()
{
printf("请输入进制数：\n");
scanf("%d",&y);
int num1;
int num2=0;
int s=0;
int i=0;
printf("请输入一个数：");
scanf("%d",&num1);
while(num1>0)
{
s = num1 % y;
num2 = s*pow(10,i) + num2;
num1 = (num1-s)/y;
i++;
}
printf("转化成%d进制后为：%d\n",y,num2);
return ;
}

void project2()
{
printf("请输入进制数：\n");
scanf("%d",&y);
int num1,num2=0;
int s,i;
i=0;
printf("请输入一个数：");
scanf("%d",&num1);
while(num1>0)
{
num2=(num1%10)*pow(y,i)+num2;
num1=num1/10;
i++;
}
printf("转化成十进制后为：%d\n",num2);
return ;
}

extern "C"
{
__declspec(dllexport)
int WINAPI icePub_binaryStringToHexString(char *strBinary,char *strHex);
}

#pragma comment(lib,"icePubDll.lib")

char strResult[1024];

我测试的都通过了啊 ，你是什么错误？

我测试十进制下的4转化成二进制，结果输出99
