Write a program to implement Algorithm 3-9, “Parse Parentheses,” matching
braces rather than parentheses. In your implementation, push the line
number into the stack rather than the opening brace. When an error
occurs, print the line number for the unmatched opening brace or
unmatched closing brace. Test your program by running the source code
through itself (there should be no errors) and then test it with the following
small program:
program.
Test brace errors.
} line 2 closing brace is not paired
No braces.
{opening brace is paired on same line}
No braces.
{opening brace paired later
No braces.
} Closing brace paired two lines up.
{{{ Line 9. Three braces--only two paired.
} First closing brace
} Second closing brace.
End of program. One opening brace left.
