void Greater(void)
{
	MatchString(">");
	if ( Token[0]=='=') {
		MatchString("=");
		Expression();
		PopCompare();
		SetGreaterOrEqual();
	} else {
		Expression();
		PopCompare();
		SetGreater();
	}
}

Example #2

File: boolean.c Project: Harnesser/LetsBuildACompiler

void LessOrEqual(void)
{
	MatchString("=");
	Expression();
	PopCompare();
	SetLessOrEqual();
}

Example #3

File: boolean.c Project: Harnesser/LetsBuildACompiler

void NotEquals(void)
{
	MatchString(">");
	Expression();
	PopCompare();
	SetNEqual();
}

File: boolean.c Project: Harnesser/LetsBuildACompiler

// operations
void Equals(void)
{
	MatchString("=");
	Expression();
	PopCompare();
	SetEqual();
}

Example #5
