this is a code for generating prime number.here i am checking the number to be divisible by 2 ,3 & 5 first & after that by 7 , 11 & 13 and after that if it is divided by any prime number from 13 to 997.
the link to problem is PRIME1 Problem - CodeChef
the link to my code is CodeChef: Practical coding for everyone
you stored primes upto 1000 , whereas primes can be much much larger than that .
Your final code is not giving any output on most of cases like
if m = 10 , n = 20;
and your first code was giving wrong output in cases like
if m=4,n = 4, out put should be a blank like but your program gives an output of integer 2.
Still there is a wrong input m=1,n=1 in ur program it is considered that 1 is a prime number
ok…thank you
ok here is the new code for the same problem

But here i am divding the number upto ceiling of sqrt only.but still getting wrong answer.
ok.fixed another problem now it should be working.problem was with for loop bracket.

Yet a lot of inputs are not working like…
testcases=2
m=1 n=2
m=2 n=5
it gives out put 1 3 5
whereas output should be 2 2 3 5
If it really helped just accept this as answer by clicking the green tick button bellow my answer
thnks.after fixing the above problem , solution is still wrong.
