10011101 - C++

What is 10011101?

10011101 is a binary number which is equal to 157 in decimal.

How to represent 10011101 in C++?

In C++, we can represent binary numbers using the prefix "0b" followed by binary digits. However, this syntax is not supported in all versions of C++. Alternatively, we can represent 10011101 in decimal and convert it to binary using bitwise operators.

One way to represent binary numbers in C++ is the following:

int binary_num = 0b10011101;

Alternatively, we can use bitwise operators to convert decimal to binary, as follows:

int decimal_num = 157;
int binary_num = 0;
int bit_position = 0;

while (decimal_num > 0)
{
    int bit = decimal_num % 2;
    binary_num = binary_num | (bit << bit_position);
    decimal_num = decimal_num / 2;
    bit_position++;
}

Here, we start by initializing binary_num and bit_position to 0, and decimal_num to the decimal representation of 10011101 (i.e., 157). Then, we loop until decimal_num becomes 0. Inside the loop, we extract the least significant bit of decimal_num using the % operator, and set the corresponding bit of binary_num using bitwise OR (|) and left shift (<<) operations. Finally, we divide decimal_num by 2 and increment bit_position.

After executing this code, binary_num should be equal to 10011101 in binary.

Conclusion

In summary, 10011101 is a binary number that can be represented in C++ using binary literals or by converting it from decimal using bitwise operators.
