Answer 1

//#include "stdafx.h"//vc++6.0加上这一行.
#include "stdio.h"
void main(void){
char binary[33],i=0,x;
int n=0;
printf("Type a binary(<33 bit)...\n");
while((x=getchar())=='0' || x=='1'){
binary[i++]=x;
if(i==33) break;
}
binary[i]='\0';
for(i=0;binary[i];(n*=2)+=binary[i++]-'0');
printf("To Dec is %d.\nTo Oct is %o.\nTo hex is %X.\n",n,n,n);
}
