When I am compiling this program I am getting some random number as output.. In Cygwin the output is 47 but in RHEL5, it is giving some negative random numbers as output.
Can anyone tell me the reason?
Code:
main()
{
printf("%d");
}
This program provokes undefined behavior since it does not follow the rules of C. You should give
printfone argument per format specifier after the format string.On common C implementations, it prints whatever happens to be on the stack after the pointer to
"%d", interpreted as an integer. On others, it may send demons flying out of your nose.
