Free pascal random 255 generator#

Readln (Guess ) If Guess =Random ( 5 ) + 1 then inc (count ) end Write ( 'Guess a number between 1 and 5 : ' ) Writeln ( 'out of 1000 generated numbers.' ) We could easily use a timer with a set of colors but we want to use random colors so they are unpredictable. The point of this program is to simply have the user click a button and the background begin to flash Random colors. We in are spare time are trying to make a 'Siezure' program.

Writeln ( 'Generated ' ,Count, ' numbers > 0.5' ) We are using the schools outdated microsoft visual basic 2003. If speed is an issue, then alternate random number generators should be considered.Įxample Program Example49 Ĭount := 0 For i := 1 to 1000 do If Random > 0.

Free pascal random 255 generator#

This implementation has a better statistical distribution than for example a Linear Congruential generator algorithm, but is considerably slower than the latter. The Free Pascal implementation of the Random routine uses the Mersenne Twister to simulate randomness. If the argument L is omitted, a Real number between 0 and 1 is returned (0 included, 1 excluded). The packed specifier means that the array will be squeezed to take up the smallest amount of memory. Most of the time it's the null-character (ordinal number 0, or ord (0)). Random returns a random number larger or equal to 0 and strictly less than L. type String packed array 0.255 of char and using some kind of terminating character to signify the end of the string.
