Look at the following two code snippets where each code counts number of letters ‘f’ and ‘s’ in a sentence:

// code 1                    //code 2

:                            :

if (c ==’f’):                if (c ==’f’):

nf++                            nf++

if (c==’s’):               elif (c==’s’):

ns++                           ns++

What is the difference between the two codes given above.



Code 1

Code 2

There are two if statements used, and each one is tested separately. Whether the result of the first is true or false , the second will always run.

if-elif statement is used. In this, if the first  condition becomes true then the program will  not check the latter conditions.
