Program Plan Intro

Program plan:

  1. str,cmpstr variablesare used for inputs
  2. int strcmparr(const char s1[], const char s2[]) function stores string array reference in two array variables and compare the strings character by character using index variable and return the difference between character values.
  3. int strcmpptr(const char *s1, const char *s2) stores string array reference in pointer variables and copy compare the strings character by character using pointer arithmetic and return the difference between character values.

Program description:

The main purpose of the program is to demonstrate the working of built-in string function strcmp() by writing the two versions of each function. One version uses the pointer arithmetic to compare the strings. Second version uses array index to compare the strings.
