修改后的C++程序
#include<iostream>
using namespace std;
void HextoBin(char deststr[],char srcstr[]);
void main()
{
char *BB1="efcdab89",BB[32]="aaaaa";
cout<<BB<<endl;
HextoBin(BB,BB1);
cout<<BB<<endl;
}
void HextoBin(char deststr[],char srcstr[]){
int k=0,w=0,i,j,a[8],total=0;
char str[4]="",stra[32];
deststr[0]=0;
for(i=0;i<8;i++){
if(srcstr[i]>='0'&&srcstr[i]<='9'){
a[i]=srcstr[i]-'0';
}
else{
a[i]=srcstr[i]-'a'+10;
}
itoa(a[i],str,2);
cout<<"測試輸出："<<str<<endl;
strcat(deststr,str);
}
}
