User input:
Getting user input is easy, just make sure to include get.e and create a prompt like so:
myprompt = prompt_string("Type a message here: )
The user's input is stored in mystring with which you can use in various situations.
Below is an example of taking input from the user and comparing it against various strings using -
the equal() function
include std/io.e
include get.e
sequence input
input = prompt_string("Type here: ")
if equal(input, "test") then
printf(STDOUT, "Test Successful\n")
elsif equal(input, "test1") then
printf(STDOUT, "Test1 Successful\n")
else
printf(STDOUT,"Unrecognized input\n")
end if
Compare Sequences
You can use a couple of built-in functions to test strings or other sequences.
They are:
compare("string1", "string2")
equal("string1, "string2")
Below is an example of using the compare function.
Notice with this function you need to check it against a number.
0 - true
1 - false
include std/io.e
sequence mystring
mystring = "hello"
if compare(mystring, "hello") = 0 then
puts(1,"The condition is true!")
else
puts(1,"The condition is false!")
end if
On the other hand, the equal() function does not need a 0 or 1 to work:
include std/io.e
sequence mystring
mystring == "hello"
if equal(mystring, "hello") then
puts(1,"The condition is true!")
else
puts(1,"The condition is false!")
end if
