How to output binary in the C language?

In C language, binary numbers can be printed using bitwise operations.

Here is an example code:

#include <stdio.h>

// 以二进制形式输出整数
void printBinary(int num) {
    int i;
    for (i = sizeof(int) * 8 - 1; i >= 0; i--) {
        if ((num >> i) & 1) {
            printf("1");
        } else {
            printf("0");
        }
    }
    printf("\n");
}

int main() {
    int num = 10;
    printf("二进制形式：");
    printBinary(num);
    return 0;
}

Running the above code will output the following results:

二进制形式：00000000000000000000000000001010

In the printBinary function, the integer is output in binary form bit by bit by using bitwise operations and loops.
