Print a prompt and wait for user input. For example,
input ("Pick a number, any number! ")prints the prompt
Pick a number, any number!and waits for the user to enter a value. The string entered by the user is evaluated as an expression, so it may be a literal constant, a variable name, or any other valid expression.
Currently,
input
only returns one value, regardless of the number of values produced by the evaluation of the expression.If you are only interested in getting a literal string value, you can call
input
with the character string"s"
as the second argument. This tells Octave to return the string entered by the user directly, without evaluating it first.Because there may be output waiting to be displayed by the pager, it is a good idea to always call
fflush (stdout)
before callinginput
. This will ensure that all pending output is written to the screen before your prompt. See Input and Output.
