Hello @rastogi.g1998,

  1. When you use == operator then you can only check for equality.

  2. strcmp() provides three different types of output:
    0: A value equal to zero when both strings are found to be identical. That is, That is, All of the characters in both strings are same.
    <0: A value less than zero is returned when the first not matching character in leftStr have lesser ASCII value than the corresponding character in rightStr.
    >0: A value greater than zero is returned when the first not matching character in leftStr have the greater ASCII value than the corresponding character in rightStr or we can also say.

So, their application depends upon your requirement.

Hope, this would help.
Give a like, if you are satisfied.
