c# - Why is my foreach printing out 2 char? -

i trying create encryption (ceasar) education , reason can't seem understand why simple code (so far) making such hazzle

static void main(string[] args)     {         string word;         int key = 0;         console.writeline("write messages");         word = console.readline();         console.writeline("enter key cypher");         key =int.parse(console.readline());         encrypt(word, key);     }      static void encrypt(string message, int key)     {         foreach (char otherword in message)         {             console.write(otherword);             console.read();         }     } 

if write example test after "write messages" , place string word , use in function encrypt, should output

t  e s t 

but whatever god forsaken reason output

t es t 

and dont understand why.

you want use console.writeline(otherword); then. spacing of newlines in output dependent on key press after console.read(); line. (for example, if press [enter], newline, if press a not.)

you should use console.readkey(true); rather console.read(); method of separating output, make key press not show up.
