Q3) Write a C program that takes two-character arrays of size 20 from the user using scanf function. Then write a function called "concatenate_strings". This function receives the strings as two pointer arguments and concatenates the strings to each other and will return the number of characters of the concatenated string. Write a second function "getSize" that takes the concatenated string and returns the size of character in number of bytes. Then print the size of character in number of bytes, the size of the string in number of bytes, and the size of string in number of characters. Note: Use pointer definition inside the functions. The array definition will be not accepted and you cannot claim credit. hint 1: pass the arguments using call-by-reference method. hint 2: Use the function prototypes: int concatenate_strings( char *string1, const char *string2 ); int getSize(const char *string4); hint 3: if first string is "Introduction" and second is "Programming", then after concatenation you have "IntroductionProgramming" and the function will return 23.

Write a C program

Q3) Write a C program that takes two-character arrays of size 20 from the user using scanf
function. Then write a function called "concatenate_strings". This function receives the strings
as two pointer arguments and concatenates the strings to each other and will return the number
of characters of the concatenated string. Write a second function "getSize" that takes the
concatenated string and returns the size of character in number of bytes. Then print the size
of character in number of bytes, the size of the string in number of bytes, and the size of string
in number of characters.
Note: Use pointer definition inside the functions. The array definition will be not accepted and
you cannot claim credit.
hint 1:
pass
the
arguments using call-by-reference method.
hint 2: Use the function prototypes:
int concatenate_strings( char *string1, const char *string2 );
int getSize(const char *string4);
hint 3: if first string is "Introduction" and second is "Programming", then after concatenation
you have "IntroductionProgramming" and the function will return 23.
