Chapter 9, Problem 2E

Explanation of Solution

Result when replacing the while statement:

The while statement given the program is “s1[i]==s2[i] && s1[i]!='\0' && s2[i]!='\0'”. This while loop will be continued till the two character strings are equal  “(s1[i]==s2[i]) ” and checks till the either of the string is not reached to the “0” “s1[i]!='\0' && s2[i]!='\0'”.

The while loop gets terminated if both the string is not equal or if any one of the string reaches the end of the string...
