PSeInt profile UNICEQ
These are the rules of the UNICEQ profile, explained simply, with an example that follows them and opens in Codoritmo with one click.

In short
What changes compared with Codoritmo's default profile:
- You can assign with = as well as <-
- Arrays start at 0
All of its rules
Marked rules differ from Codoritmo's default profile; everything else behaves the same.
Variables
How they are declared and when they can be used.
- Declare variables with Definir
- Optional. You can use a variable without declaring it: its type comes from the first value you store in it.
- Give a value before use
- Not checked. It's still good practice to give every variable a value before using it.
- Protected Para counter
- You can change the counter inside the
Paraand keep using it after the loop ends. - Accents and ñ in names
- Allowed: a variable can be called
añoorposición.
Writing style
Punctuation, closing words and how values are assigned.
- Semicolon at the end
- Optional. You can end statements with
;or leave it out. - Relaxed syntax
- Accepts handy variants:
Fin Sias two words, optionalEntoncesandHacer,Mientras QueandDesdein loops, and values inEscribirseparated by spaces. - Assign with =Differs from default
- Allowed: besides
x <- 5you can writex = 5. Inside a condition,=is still a comparison.
Operators and conditions
How comparisons are written and text is put together.
- Word operators
- You can write
Y,O,NOandMOD(and, or, not, remainder) as well as their symbols&,|,~and%. - Plain-language conditions
- Accepts conditions such as
x Es Par(is even),x Es Mayor Que 5(is greater than 5) orx Es Divisible Por 3. - Join text with +
- Allowed:
"Hola, " + nombremakes a single piece of text.
Arrays
Where indexes start and how the size is set.
- First array indexDiffers from default
- Arrays start at 0: after
Dimension notas[3]the slots arenotas[0],notas[1]andnotas[2]. - Array size from a variable
- Allowed: you can read
nand then writeDimension datos[n]. - Resize arrays
- You can change the size of an existing array with
Redimensionar.
Loops and Segun
Which ways of repeating and choosing between cases it accepts.
- Para Cada loop
- Available:
Para Cada nota de notas Hacergoes through every slot of an array. - Repetir … Mientras Que
- A
Repetirloop can end withHasta Que condition(until) orMientras Que condition(while). - Para counting down
- If the start is greater than the end,
Paracounts down one by one even withoutCon Paso -1. - Segun with whole numbers
- The value a
Segunchecks can also be text, with options such as"a".
Subroutines and text functions
Which extra tools you get to organise the program.
- Your own subroutines and functions
- You can write your own
SubProcesoorFuncionto split the program into parts. - Text functions
- Available:
Longitud,Subcadena,Mayusculas,MinusculasandConcatenar(length, substring, upper case, lower case, join).
An example that follows these rules
It works out the average of three marks. It's written for this profile, and the comments point out what changes compared with the default. We checked it with Codoritmo's interpreter using these same rules.
// Example written with the rules of the UNICEQ profileAlgoritmo PerfilUNICEQ Dimension notas[3] // Arrays start at 0: the slots are 0, 1 and 2 notas[0] <- 8 notas[1] <- 9 notas[2] <- 7 // This profile also lets you assign with = suma = 0 Para i <- 0 Hasta 2 Hacer suma <- suma + notas[i] FinPara promedio <- suma / 3 nombre <- "Ana" Escribir "Hi, ", nombre Escribir "Average: ", promedio Si promedio >= 7 Y promedio <= 10 Entonces Escribir "Passed" SiNo Escribir "Failed" FinSi Si suma Es Par Entonces Escribir "The sum is even: ", suma SiNo Escribir "The sum is odd: ", suma FinSiFinAlgoritmoWhat it prints
This is the example's real output, run with the UNICEQ profile.
Hi, Ana Average: 8 Passed The sum is even: 24
Profiles with the same rules
One other profile uses exactly these rules; what you practise here works for it too.
