C ++で2つの2進数を追加するにはどうすればよいですか?正しいロジックは何ですか?
これが私の努力ですが、正しくないようです:
#include <iostream>
using namespace std;
int main()
{
int a[3];
int b[3];
int carry = 0;
int result[7];
a[0] = 1;
a[1] = 0;
a[2] = 0;
a[3] = 1;
b[0] = 1;
b[1] = 1;
b[2] = 1;
b[3] = 1;
for(int i = 0; i <= 3; i++)
{
if(a[i] + b[i] + carry == 0)
{
result[i] = 0;
carry = 0;
}
if(a[i] + b[i] + carry == 1)
{
result[i] = 0;
carry = 0;
}
if(a[i] + b[i] + carry == 2)
{
result[i] = 0;
carry = 1;
}
if(a[i] + b[i] + carry > 2)
{
result[i] = 1;
carry = 1;
}
}
for(int j = 0; j <= 7; j++)
{
cout<<result[j]<<" ";
}
system("pause");
}
