A C compiler that parses this code will contain at least the following symbol table entries
Consider the following program written in C:
// Declare an external function
extern double bar(double x);
// Define a public function
double foo(int count)
{
double sum = 0.0;
// Sum all the values bar(1) to bar(count)
for (int i = 1; i <= count; i++)
sum += bar((double) i);
return sum;
}
A C compiler that parses this code will contain at least the following symbol table entries:
| Symbol name | Type | Scope |
|---|---|---|
bar |
function, double | extern |
x |
double | function parameter |
foo |
function, double | global |
count |
int | function parameter |
sum |
double | block local |
i |
int | for-loop statement |
In addition, the symbol table will also contain entries generated by the compiler for intermediate expression values (e.g., the expression that casts the i loop variable into a double, and the return value of the call to function bar()), statement labels, and so forth.
