Question

I just want to write a simple text file:

ofstream test;
test.clear();
test.open("test.txt",ios::out);
float var = 132.26;
BYTE var2[2];
var2[0] = 45; 
var2[1] = 55;
test << var << (BYTE)var2[0] << (BYTE)var2[1];
test.close();

But in the output file I get:

132.26-7

I don’t get what the problem is…

Answer 1

BYTE is nothing but an alias for unsigned char. By default, when you output a char in a stream, it is converted to its ASCII character. In the ASCII table, the character 45 is ‘-‘ and the character 55 is ‘7’.

Try this instead:

test << var << (int)var2[0] << (int)var2[1];
