// Convert Decimal to Binary in C using Function

// It's the driver function

// This function will convert number decimal to binary
long long convert(int x) {
    long long bin = 0;
    int rem, i = 1, step = 1;

    while (x != 0) {
        rem = x % 2;
        x /= 2;
        bin += rem * i;
        i *= 10;
    }
    return bin;
