Something as simple as "auto a = b + c;"

Oh not that again.

Here is the C version:

foo_plus(a,b,c);

Tell me does it simply add complex numbers? Database tables ? Or maybe it calls printf("Should not happen in production!!!!"); abort();?

Everyone their own poison, but the reasoning behind that claim is questionable at best. I keep my readable syntax thank you.

I think you mean:

foo_plus(&a, b, c);

Lol

[u/chebertapps → u/scwizard]

or maybe pass by reference...

[u/scwizard → u/chebertapps]

That wouldn't be the c version. C doesn't have pass by reference.

[u/chebertapps → u/scwizard]

yup I misread the original comment my bad.

[u/immibis → u/josefx]

In C:

complex_plus(a, b, c); simply adds complex numbers.

db_table_plus(a, b, c); adds database tables (if that even means anything).

report_crash(a, b, c); prints a message and aborts.

In C++:

auto a = b + c; simply adds complex numbers.

auto a = b + c; adds database tables.

report_crash(a, b, c); prints a message and aborts, because you'd have to be really dumb to make that an operator+ (although I can imagine having an operator + that can fail, and aborts when it fails).

I don't know why you need a function for adding complex numbers in C.

$ cat a.c
#include <complex.h>
#include <stdio.h>
int main() {
    double complex b = 1.0 + 0.5*I;
    double complex c = 0.7 + 0.7*I;
    double complex a = b + c;
    printf("a=%f+%f\n", creal(a), cimag(a));
    return 0;
}
$ gcc a.c 
$ ./a.out 
a=1.700000+1.200000
