I want to convert a string, using the string class - to Binary. What is the fast way to do this character by character. Loop? Or is there some function out there that will convert for me? 1's and 0's binary.
A string being:
#include <string>
using namespace std;
int main(){
myString = "Hello World";
}
To convert a string to binary, we first append the string's individual ASCII values to a list ( l ) using the ord(_string) function. This function gives the ASCII value of the string (i.e., ord(H) = 72 , ord(e) = 101). Then, from the list of ASCII values we can convert them to binary using bin(_integer) .
To convert integer to binary, start with the integer in question and divide it by 2 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero. Then just write out the remainders in the reverse order.
In Python, you can simply use the bin() function to convert from a decimal value to its corresponding binary value. And similarly, the int() function to convert a binary to its decimal value. The int() function takes as second argument the base of the number to be converted, which is 2 in case of binary numbers.
WriteFile function (MSDN)
Using std::bitset
would work:
#include <string>
#include <bitset>
#include <iostream>
using namespace std;
int main(){
string myString = "Hello World";
for (std::size_t i = 0; i < myString.size(); ++i)
{
cout << bitset<8>(myString.c_str()[i]) << endl;
}
}
Output:
01001000
01100101
01101100
01101100
01101111
00100000
01010111
01101111
01110010
01101100
01100100
