用C语言将二进制转换成十进制

在C语言中，将二进制转换为十进制可以使用循环和位操作来实现。以下是一个简单的函数示例：

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

// Function to convert binary to decimal
int bin_to_dec(int binary) {
    int decimal = 0;
    int base = 1;

    // Iterate through the binary number from right to left (least significant bit)
    while (binary > 0) {
        int remainder = binary % 10;  // Get the remainder after division by 10
        decimal += remainder * base;   // Add the current digit to the result
        binary /= 10;                // Shift binary number to the left
        base *= 2;                   // Double the base for each iteration
    }

    return decimal;
}

int main() {
    int binary_num = 101010; // Replace with your binary value
    int decimal_num = bin_to_dec(binary_num);
    printf("Binary %d is equal to decimal %d\n", binary_num, decimal_num);
