Clang:

/tmp/webcompile/_32245_0.cc:5:11: error: expected '}'
    int k;
          ^
/tmp/webcompile/_32245_0.cc:1:12: note: to match this '{'
void foo() {
           ^
1 error generated.

In the worst case, it will tell you from which point you should start looking.

Using an editor that can jump between braces (e.g. % in vim) makes it trivial
to find if you've indented your code sensibly. As Andrew said in comment 1, the
compiler's hint might be completely misleading.

With latest GCC, it works for C++:

LANG= g++ t.c
t.c: In function 'void foo()':
t.c:4:11: error: expected '}' at end of input
    4 |     int k;
      |           ^
t.c:1:12: note: to match this '{'
    1 | void foo() {
      |            ^

But it's sometimes indeed completely misleading (PR109356).

Still does not work for C:

LANG= cc t.c
t.c: In function 'foo':
t.c:4:5: error: expected declaration or statement at end of input
    4 |     int k;
      |     ^~~

Can we close this or reset Component field?

Component field reset.
