Step 1: char str1[] = "Hello"; The variable str1 is declared as an array of characters
and initialized with a string "Hello".
Step 2: char str2[] = "Hello"; The variable str2 is declared as an array of characters
and initialized with a string "Hello".
We have use strcmp(s1,s2) function to compare strings.
Step 3: if(str1 == str2) here the address of str1 and str2 are compared. The address
of both variable is not same. Hence the if condition is failed.
Step 4: At the else part it prints "Unequal".
