Please give the entire code that can be copied directly, please run the program in any terminal (ubuntu), and screenshot the command and the result. Thank you! Please provide the screenshot, I will upvote if the answer is correct.

==================================================================

Please modify the C program to detect tokens in a C program, to get the following output:

----------------------------

'int' IS A KEYWORD 'a' IS A VALID IDENTIFIER '=' IS AN OPERATOR '2' IS AN INTEGER 'b' IS A VALID IDENTIFIER '=' IS AN OPERATOR '3' IS AN INTEGER 'c' IS A VALID IDENTIFIER '=' IS AN OPERATOR 'b' IS A VALID IDENTIFIER '%' IS AN OPERATOR 'a' IS A VALID IDENTIFIER

========================================================

test the program with

--------------------------------

int main() { // maximum legth of string is 100 here char str[1000] = "int a=2, b=3, c = b % a;"; parse(str); // calling the parse function return (0); }
