Why Use `and` and `or` Instead of `&&` and `||` in C  ?

Alternate Operators for Logical Operations in C

Despite the popularity of the operators && (and) and || (or), their written versions and and or exist as alternate tokens in C . This raises questions about their origin and usage.

Origins in C and Compatibility with C

The written versions of logical operators originated in C with the header. This header provided definitions that allowed programmers to use the written form if they lacked the symbols for the operators on their keyboards.

In C , these tokens became known as alternate tokens, eliminating the need for any additional include.

Syntax and Semantics

The syntax and semantics of the written versions are identical to their symbol counterparts. They are parsed as the same tokens, resulting in the same results.

Reasons for Their Infrequency

While these operators are technically valid C , their usage is uncommon. Primarily, the readability of and and or is deemed lower than their symbolic counterparts, && and ||, respectively. Their rarity tends to hinder readability more than enhance it.

Usage Considerations

While alternate tokens for logical operators can be used, it's generally advisable to stick with the more common && and || symbols for clarity and readability. However, it's worth noting that their usage has seen a slight increase in recent times, potentially indicating a shift in their popularity.
