Binary Conversion

Binary is a base-2 number system where numbers are represented using only 0s and 1s. Each position represents a power of 2, and we can convert decimal numbers to binary through repeated division by 2.

Conversion Steps:

C Code Example:

// Function to convert decimal to binary
void decimalToBinary(int decimal) {
    // Cannot store numbers larger than 32 bits
    int binary[32];
    int i = 0;
    
    // Continue dividing by 2 until quotient becomes 0
    while (decimal > 0) {
        binary[i] = decimal % 2;
        decimal = decimal / 2;
        i++;
    }
    
    // Print binary array in reverse order
    for (int j = i - 1; j >= 0; j--) {
        printf("%d", binary[j]);
    }
}
