Step by Step solution about How to resolve the algorithm Copy stdin to stdout step by step in the Smalltalk programming language
Source code in the smalltalk programming language
"using Stream class's bulk copy method:"
Stdin copyToEndInto:Stdout.
"line wise"
[Stdin atEnd] whileFalse:[ Stdout nextPutLine:(Stdin nextLine) ].
"character wise"
[Stdin atEnd] whileFalse:[ Stdout nextPut:(Stdin next) ].
"no EOF test, but handle EOF Exception"
[
[ Stdout nextPut:(Stdin next) ] loop.
] on: StreamError do:[]
