利用栈结构二进制数转十进制数代码实现c++

#include<string>#include<iostream>#include<cmath>#define MAXLEN 50using namespace std;struct StackType{char data[MAXLEN];int top;};StackType*STInit(){StackType*s;if(s=new StackType){s->top=0;return s;}return NULL;}StackType*STPush(StackType*s,char e){if(s->top==MAXLEN)cout<<"栈溢出！"<<endl;s->data[++s->top]=e;return s;}char STPop(StackType*s){if(s->top==0){cout<<"栈为空！"<<endl;exit(0);}return s->data[s->top--];}int main(){StackType*s;int i,len,sum=0;char e,h;cout<<"请输入二进制数："<<endl;s=STInit();cin>>e;while(e!='#'){STPush(s,e);cin>>e;}len=s->top;for(i=0;i<len;i++){sum=sum+(STPop(s)-48)*pow(2,double(i));}cout<<sum<<endl;system("pause");return sum;}
