Chapter 22, Problem 22.31E

Program Plan Intro

Program Plan:

• Include header files.
• Start “main()” function.
• Accept two strings “s1” and “s2” to compare.
• Use “strlen()” to compare length of string “s1” with length of “s2”. If length of string “s1” is greater, put length of “s1” in “len”, else put length of string “s2” in “len”. It is required for strncmp function which has following syntax:

strncmp(,string2>,n); where n is number of characters to be compared.


• Use strncmp function to compare s1, s2, and using “len” as n and store the result in variable “compare”.
• Use if construct to check if “compare” is equal to 0, then display “Both strings are equal.".
else check if compare> 0, which will display “First string is greater than second.". Else display “First string is less than second."

• Return and exit.
