C_17 Operators in C - Part 5 (Logical Operators) | C Programming Tutorials

[@venkatakrishnareddykarri6603]

In the example that's used to explain logical AND, a = 10 and b = 5, so b < a becomes TRUE. But while explaining, it's stated as FALSE, which needs to be corrected.

Result when && at the end = JK1 and Result with || at the end is also JK1. This is so because Logical && has a positive value at first, then the result is automatically TRUE which is 1, and logical OR (||) already have one and both values as TRUE, so, result is equal to 1
