C语言二进制转十进制源码

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
#include

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;
}
