Aim : To write a C$++$Program to create symbol table

Detailed Description of Exercise$2$

A Symbol table is a data structure used by the compiler, where each identifier in program's soure code is stored along with information associated with it relating to its declaration. It stores identifier as well as it's associated attributes like scope, type, line$-$number of occurrence, etc. Write a $C++$ program to construct symbol table for an input $C$ program.

Test case $1$

Sample Input:

Enter Program $ for termination:

void main$()$

i

int $a=20$;

printf$("\%)/$a$),$ a$)$;

$\}$

Sample Output:

$\backslash$table$[[$Name$,$Type,Size,Address$],[$a$,$int,$4,2024]]$

Test case $2$

Sample Input:

Enter Program $ for termination:

void main$()$

$\{$

int num$1,$num$2,$sum;

scanf$("\%$d$\%$d$",$&num$1,$&num$2)$

sum$=$num$1+$num$2$;

printf$("\%$ d$",$sum$)$;

is

Sample Output:

$\backslash$table$[[$Name$,$Type,Size,Address$]]$

$\backslash$table$[[$num$1,$int,$4,2024],[$num$2,$int,$4,3012],[$sum$,$int,$4,3048]]$
