Question 1 1 / 1 pts
Consider the following code:
Token LexicalAnalyzer::GetToken()
{
input.GetChar(c);
switch (c) {
case '=':
input.GetChar(c);
if (c == ’=') {
tmp.token_type = EQEQ;
} else if (c == ’<') {
tmp.token_type = EQLT;
} else if (c == ’>') {
tmp.token_type = EQGT;
} else
tmp.token_type = ERROR;
return tmp;
default:
tmp.token_type = ERROR;
return tmp;
}
}
In the code, input.GetChar() gets the next character from standard input. If GetToken() is called four times on input <==<==,
how many times is ERROR returned
