Unveiling the Enigma of the '>?=' Operator in C

In the realm of C , a peculiar operator known as '>?=' has emerged, leaving many perplexed about its purpose. This mysterious operator, briefly referenced in a compatibility comment in the BigInt library, has piqued the curiosity of countless programmers.

What Lies Behind the Operator's Syntax?

The '>?=' operator, which was once revered in the g compiler's fold, has vanished from the coding landscape in GCC versions 4.2 and beyond. However, its legacy persists in some corners of the C community. Its core functionality lies in assigning the maximum value between two variables.

A Closer Look at its Inner Workings

To fully comprehend the '>?=' operator, it's essential to understand its algorithmic equivalent:

a = max(a,b);

This code snippet accomplishes the same task as '>?=' operator, assigning the greater value between 'a' and 'b' back to 'a'.

A Sibling with a Different Agenda

Alongside the '>?=' operator, another operator exists: 'a = b'. This operator, as one might suspect, assigns the minimum value between 'a' and 'b' back to 'a'. Its implementation follows this pattern:

a = min(a, b);

Conclusion

The '>?=' operator, once a valuable tool in the g compiler, is now a relict of the past. Its functionality, however, can easily be replicated by embracing the power of 'a = max(a,b);'. And so, the mystery of the '>?=' operator unravels, revealing its hidden purpose and leaving behind a legacy of coding knowledge.
