What is the newline character in Free Basic?

[dodicat]

printf can be used.
Remember to put the escape character in front of the string to handle things like \n
http://www.cplusplus.com/reference/cstdio/printf/
I have made one small difference to suit freebasic in the first printf.
(NOTE: I use #macro as a convenient way to hold comments, it has nothing to do with running code)

Code: Select all

#include "crt.bi"

   printf (!"Characters: %c %c \n", asc("a"), 65)
   printf (!"Decimals: %d %ld\n", 1977, 650000L)
   printf (!"Preceding with blanks: %10d \n", 1977)
   printf (!"Preceding with zeros: %010d \n", 1977)
   printf (!"Some different radices: %d %x %o %#x %#o \n", 100, 100, 100, 100, 100)
   printf (!"floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416)
   printf (!"Width trick: %*d \n", 5, 10)
   printf (!"%s \n", "A string")
 '===========================  
   
 #macro C_code_from_the_link

   return 0;

@dodicat,

NOTE: I use #macro as a convenient way to hold comments, it has nothing to do with running code

I don't see a reason for that, you could simply stick them into a multiline comment: /' ... '/ ???
Seems to me to be a 'clean' solution (as provided by the language itself).

[dodicat]

I always get mixed up and have to redo them.

Thanks all of you.

Print numbers as string that is all

Code: Select all

print str(sqr(2))

If you print numbers the space is a place holder for an minus sign

Code: Select all

print -1
print atn(1)*4

Imagine you print a table in the console
without the placeholder the result of negative and positive numbers would look ugly right ?

try it if you like

Code: Select all

for x as integer = 1 to 4
  for y as integer = 1 to 4
    print int((rnd-rnd)*9),
  next
  print
next
print
for x as integer = 1 to 4
  for y as integer = 1 to 4
    print str(int((rnd-rnd)*9)),
  next
  print
next
print
sleep
