Algorithm and Flowchart to find the largest number among three numbers

Algorithm:

1. Start
2. Read Three Number A,B and C
3. Check, Is A is greater than B (A>B)
4.  If Yes, Check, Is A is greater than C (A>C)
   • 4.1 If Yes, print “A is Largest Number”
   • 4.2 If No, print “C is Largest Number”
5. If No, Check, Is B is greater than C (B>C)
   • 5.1 If Yes, print “B is Largest Number”
   • 5.2 If No, print “C is Largest Number”
6. Stop

Algorithm

1. Start
2. Read Three Number A,B and C
3. if (A > B && A > C)
   • Print “A is Largest Number”
4. Else if (B > A && B >C)
   • Print “B is Largest Number”
5. Else
   • Print “C is Largest Number”
6. Stop
