Is there any plugin or function in KEIL or other compilation environment that can help check if there is an error like if (a=1)? Of course, this error is definitely not just if (a=1), it may also be if (aaa=1), if (xx=1), if (ekwks=1) and so on.

String matching search.

It seems there was a warning.

vscode has it.

You can try using cppcheck to check.

It should be possible to detect it.

Keil does not report an error, but there is a warning...

Generally, a warning will be given, such as Keil C51: warning C276: constant in condition expression

Because this is not a syntax error, just a warning, the build will continue to complete.

if (1==a)

Comparison: In comparison, the right value (here the constant 1) can appear on the left.

Assignment: An rvalue can appear on the right side of an assignment operator , but not on the left side . The constant 1 is an rvalue .

if (1=a) the c compiler will give you an error.
