.txt to ASCII Code Array

[rudster816]

How would I go about importing a text in to an array in ASCII code. Not the actual characters, but the number representation.

e.g. the .txt contains
"sample text"

I want it to load

115 97 109 112 108 101 32 116 101 120 116

in to a 2D array.

I dont really know how to approach this other than writing a separate program outside of what I want to do that loads each individual character and "manually" change it to a number.

Thanks

Er, that's exactly what happens when you load strings from a file normally.

1 2 3 4 5 6 7 8 9 10 11 12 13

#include <iostream> using namespace std; int main() { const char s[] = "Hello world!"; for (unsigned n = 0; n < sizeof( s ) - 1; n++) cout << (int)s[ n ] << " "; cout << endl; return 0; }

72 101 108 108 111 32 119 111 114 108 100 33

If you want to copy a char array to an int array, use the copy() algorithm:

#include <algorithm>
...
const char s[] = "Hello world!";
int xs[ sizeof( s ) - 1 ];

std::copy( s, s + sizeof( s ) - 1, xs );

Etc. Hope this helps.

Thanks, that worked beautifully.

Another possibly noobish question. How would I convert an ASCII number taken from an array to its corresponding letter\symbol?

EDIT:

Figured it out (I think)

You've got it.

The only difference between and ASCII value and what gets printed is whether or not you are looking at it as a char or an int.

cout << (int)65 << endl;
cout << (char)65 << endl;

Enjoy!
