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.
