Program to print the first 10 prime numbers

Prime Numbers

Prime numbers are the natural numbers that can be divided by their self or by 1 without any remainder.

For example: 2, 3, 5, 7, 11, 13, 17 etc.

NOTE: 2 is the only even prime number.

In this program, we need to print the first 10 prime numbers: 2,3,5,7,11,13,17,19,23,29.

Algorithm

  • STEP 1: START
  • STEP 2: SET ct =0, n =0, i= 1, j=1
  • STEP 3: REPEAT STEP 4 to 12 UNTIL n<10
  • STEP 4: j =1
  • STEP 5: ct =0
  • STEP 6: REPEAT STEP 7 to 9 UNTIL j<=i
  • STEP 7: if i%j==0 then
  • STEP 8: ct = ct+1
  • STEP 9: j =j+1
  • STEP 10: if ct==2 then PRINT i
  • STEP 11: n =n+1
  • STEP 12: i = i+1
  • STEP 13: END
