Program To Print Pattern 1

84

Write a program to print the following pattern.

In this pattern program, we are going to draw above pattern on the output screen with the help of various loops.

Algorithm:

• STEP 1: START
• STEP 2: SET lines= 10
• STEP 3: SET space=(lines/2)-2
• STEP 4: SET i=1 REPEAT STEP 5 to STEP 17 UNTIL i is less than or equals to lines.
• STEP 5: SET flag1=0
  SET l=1
• STEP 6: REPEAT STEP 7 and 8 UNTIL l is less than or equals to i
• STEP 7: IF flag1 is not true
  PRINT ‘*’ and INCREMENT flag1 by 1
  ELSE PRINT BLANK SPACE “” WITH “*”
• STEP 8: SET l=l+1
• STEP 9: SET l=1
• STEP 10: REPEAT STEP 11 UNTIL l is less than or equals to space
• STEP 11: PRINT “” and SET l=l+1
• STEP 12: DECREMENT space by 4.
• STEP 13: SET l=1 and SET flag=1
• STEP 14: REPEAT STEP 15 UNTIL l is less than or equals to i
• STEP 15: IF flag is not true PRINT * and increment flag by 1.
  ELSE PRINT BLANK SPACE “” WITH * .
• STEP 16: PRINT new line
• STEP 17: SET i=i+1
• STEP 18: INCREMENT space by 4
• STEP 19: SET i=lines/2
• STEP 20: REPEAT STEP 21 to STEP 25 UNTIL i is greater than 1
• STEP 21: SET flag=0 SET l=1
• STEP 22: REPEAT STEP 23 and 24 UNTIL l is less than or equals to i
• STEP 23: IF flag is not true PRINT *
  ELSE PRINT “” + *
• STEP 24: SET l=l+1
• STEP 25: PRINT new line, SET i=i-1
• STEP 26: EXIT
