Create an Convert Decimal to Binary Program in C++ with Free Codes

Starting – Decimal to Binary

Converting Decimal to Binary means a decimal (base-10) number to its binary (base-2) equivalent is a fundamental operations in computer science and digital electronics. Binary numbers are composed of only two digits, 0 and 1, making them essential for representing and manipulating data in computing systems. Implementing Decimal to Binary Conversion in C++ involves understanding a basic arithmetic operations and bitwise operations.

Formula for Decimal to Binary Conversion

To convert a decimal number to binary:

1. Initialize an empty string or array to store binary digits.
2. While decimal>0:
   • Compute remainder=decimal%2.
   • Append remainder to the beginning (or end, then reverse later) of the binary representation.
   • Update decimal=decimal/2.
3. Reverse the binary representation (if appended from end to beginning) to get the correct binary format.

C++ Codes for Project

#include <iostream>
#include <string>
#include <algorithm> // for std::reverse

std::string decimalToBinary(int decimal) {
    if (decimal == 0)
        return "0";

    std::string binary = "";
    while (decimal > 0) {
        int remainder = decimal % 2;
        binary += std::to_string(remainder);
        decimal /= 2;
    }

    // Reverse the string to get correct binary representation
    std::reverse(binary.begin(), binary.end());

    return binary;
}

int main() {
    int decimal;
    std::cout << "Enter a decimal number: ";
    std::cin >> decimal;

    std::string binary = decimalToBinary(decimal);
    std::cout << "Binary representation: " << binary << std::endl;

    return 0;
}
