Purpose:

Use of POINTER ONLY notation with malloc() function usage. NO INDEX or SQUARE BRACKET USAGE!

Passing pointers between functions

Using characters and character pointers

Description

Implement a C program that will read in two character strings and store them. Then count the number of characters in the string and display their size. Then malloc( ) enough space for both strings and combine them together.

void string_Size (char *): This function takes character pointer used for the string that was read in and will count the number of characters in a string.

int string_Compare (char *, char *): This function takes two character pointers and checks to see if the two strings are identical. The int return type will be used to communicate if the strings are identical = 1 means identical, -1 means not identical.

int string_Combine(char *, int size1, char *, int size2): This function will take the character pointer for both strings and combine the two into a new malloc( ) string space.

Sample output

$ ./a.out

Enter String 1: hello world

Enter String 2: hello world

String 1 length is 11

String 2 length is 11

The strings are identical

The strings combined are: hello world hello world

Enter String 1: fred

Enter String 2: sue

String 1 length is 4

String 2 length is 3

The strings are not identical

The strings combined are: fred sue

Enter String 1: I love

Enter String 2: CS1050

String 1 length is 6

String 2 length is 6

The strings are not identical

The strings combined are: I love CS1050

Enter String 1: exit
