using fstream to read every character including spaces and newline

Question

I wanted to use fstream to read a txt file.

I am using inFile >> characterToConvert, but the problem is that this omits any spaces an

Answer 1

I also find that the get() method of ifstream object can also read all the characters of the file, which do not require unset std::ios_base::skipws. Quote from C++ Primer:

Several of the unformatted operations deal with a stream one byte at a time. These operations, which are described in Table 17.19, read rather ignore whitespaces.

These operations are list as below: is.get(), os.put(), is.putback(), is.unget() and is.peek().

Below is a minimum working code

#include 
#include 
#include 

int main(){
    std::ifstream in_file("input.txt");

    char s;

    if (in_file.is_open()){
        int count = 0;
        while (in_file.get(s)){

            std::cout << count << ": "<< (int)s <<'\n';
            count++;
        }

    }
    else{
        std::cout << "Unable to open input.txt.\n";
    }
    in_file.close();

    return 0;
 }

The content of the input file (cat input.txt) is

ab cd
ef gh

The output of the program is:

0: 97
1: 98
2: 32
3: 99
4: 100
5: 10
6: 101
7: 102
8: 32
9: 103
10: 104
11: 32
12: 10

10 and 32 are decimal representation of newline and space character. Obviously, all characters have been read.
