将开发过程重要的一些代码片段备份一次，下边代码内容是关于C语言二进制转十进制的代码。

#include <iostream>#include <string>using namespace std;unsigned int pow(unsigned int a, unsigned int n);int main(){ string binary; unsigned int decimal = 0; cout << "Enter a binary number: "; cin >> binary; for(int i = binary.length()-1; i >= 0; i--) { if(binary[i] > '1' || binary[i] < '0') { cout << "Invalid binary number!" << endl; return 1; } else { } } cout << "Decimal: " << decimal << endl; return 0;}unsigned int pow(unsigned int a, unsigned int n){ unsigned int r = 1; return r;}
