写一个c语言程序，实现二进制到十进制的转换

#include <stdio.h>
#include <math.h>

int main() {
long long binaryNumber;
int decimalNumber = 0, i = 0, remainder;

printf("请输入一个二进制数: ");
scanf("%lld", &binaryNumber);

// 将二进制数转换为十进制数
while (binaryNumber != 0) {
remainder = binaryNumber % 10;
binaryNumber /= 10;
decimalNumber += remainder * pow(2, i);
++i;
}

printf("转换后的十进制数为: %d", decimalNumber);

return 0;
}
