Printing Binary in C

To print binary numbers in C, you can use the bitwise operators and loops to convert decimal numbers to binary representation. Here's an example code snippet that demonstrates how to print a binary number in C:

#include <stdio.h>

void printBinary(int num) {
    int i;
    for (i = sizeof(num) * 8 - 1; i >= 0; i--) {
        if (num & (1 << i))
            printf("1");
        else
            printf("0");
    }
    printf("\n");
}

int main() {
    int decimal = 10;
    printf("Binary representation of %d: ", decimal);
    printBinary(decimal);
    return 0;
}

Explanation of the code: 1. The printBinary function takes an integer num as input and prints its binary representation. 2. The loop iterates from the most significant bit (MSB) to the least significant bit (LSB) of the number. 3. Inside the loop, the bitwise AND operator (&) is used to check if the bit at the current position is set or not. 4. If the bit is set, the function prints "1"; otherwise, it prints "0". 5. Finally, the main function calls printBinary with a decimal number and prints the binary representation.

Note: The code provided is a basic example to demonstrate how to print binary numbers in C. It assumes that the size of an integer is 4 bytes (32 bits). If you are working with a different data type or platform, you may need to modify the code accordingly.
