Program Plan Intro

Program plan:

  1. str1,str2,str3,str4 variablesare used for inputs
  2. char *strcpyptr(char *dest, const char *src) function stores string array reference in pointer variables and copy srcto deststring using pointer arithmetic and return the copied string.
  3. char *strcpyarr(char dest[], const char src[]) function stores string array reference in two array variables and copy srcto deststring using array index and return the copied string.
  4. char *strcatarr(char src[], char dest[])) function stores string array reference in pointer variables and perform concatenation using srcanddeststrings using pointer arithmetic and return the resultant string.
  5. char *strcatptr(char *src, const char *dest) function stores string array reference in two array variables and perform concatenation using srcand dest using array index and return the resultant string.

Program description:

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