Hello! Need help in C++, C, or Java.
I need to open a .txt file and have the program read and tokenize each character. The program should be able to parse the file and then print out each char the file has, say what type of token it is, the lexeme, and which line and column the lexeme is found.
for example: file.txt has: and the output should look like: start reading to scan file: file.txt keyword, symbol: import line:1 string literal, symbol: "scl.h" line 1 keyword, symbol: function line: 3 keyword, symbol: main line: 3 keyword, symbol: return line: 3 keyword, symbol: type line: 3 keyword, symbol: integer line: 3 keyword, symbol: is line: 3 keyword, symbol: variables line: 4 keyword, symbol: define line: 5 identifier, symbol: x line: 5 keyword, symbol: of line: 5 keyword, symbol: type line: 5 keyword, symbol: double line: 5 keyword, symbol: begin line: 6 keyword, symbol: display line: 7 string literal, symbol: "Welcome to the world of SCL" line 7 keyword, symbol: set line: 8 identifier, symbol: x line: 8 assignment, symbol: = line: 8 real constant, symbol: 45.95 line: 8 etc
import "scl.h" implementations function main return type integer is variables define x of type double // a variable declaration begin display "Welcome to the world of SCL" set x = 45.95 // assigns a value to variable x display "Value of x: , X exit // execution terminates OK endfun mainStep by Step Solution
