Create a program P1 which takes as input a base 10 number N1 (the numbers for the variables are important). Given N1, P1 will print a program P2. P2 will take as input a base 10 number N2 and output N1+N2.

P1 and P2 have to be in the same language.

If your language doesn't have STDIN, for P1 and P2 you may specify a placeholder in your answer where the "input" would be.

The person who creates the shortest scoring program wins. Have fun, everyone!

# Ruby, 28 bytes

puts"puts #{gets}+gets.to_i"

puts"puts                     # print P2, which prints
#{gets}             # P1's input value, interpolated
+gets.to_i"  # plus P2's input value

For instance, if the input to P1 is 10, then P2 is

puts 10+gets.to_i

STDIN is ugly in J because you have to use foreigns.

## ESCR, 35 bytes

show "show [+ [arg 1] " [arg 1] "]"

The SHOW command writes to standard output. The parameters in quotes are just fixed strings. The ARG function returns a numbered argument. In the case of programs, these are command line parameters. Running this program with 13 as example parameter yields:

show [+ [arg 1] 13]

Which writes the value of the first command line parameter plus 13 to standard output.
