十进制转二进制的C语言入门编程

十进制转换成二进制的基本思想是不断除以2并取余数，直到商为0。以下是使用C语言实现十进制转二进制的一个简单入门示例：

#include <stdio.h>
#include <string.h>

// Function to convert decimal to binary
void decToBinary(int num) {
    int binary[32] = {0}; // Array to store the binary digits (enough for 32-bit numbers)
    int i = 0;

    while (num > 0) {
        binary[i++] = num % 2; // Get the remainder after dividing by 2
        num /= 2; // Divide the number by 2 and remove the last digit
    }

    // Print the binary representation from end to beginning (reverse order)
    for (int j = i - 1; j >= 0; j--) {
        printf("%d", binary[j]);
    }
}

int main() {
    int decimal;
    printf("Enter a decimal number: ");
    scanf("%d", &decimal);

    decToBinary(decimal);
    printf("\nBinary representation is: ");
    
    return 0;
}
