'==' is the equality operator that checks if two values are equal, but it does not consider the data type. For example, `0 == '0'` is true. On the other hand, '===' is the identity operator that checks if two values are equal and of the same data type. For instance, `0 === '0'` is false because one is an integer and the other is a string. Use '===' for strict type checking.

In C, ++i is the pre-increment operator, meaning the value of 'i' is incremented first, then used. i++ is the post-increment operator, which means the current value of 'i' is used first, and only after that, 'i' is incremented. This distinction is important when used within expressions. 
 
int i = 5;
printf("%d", ++i); // Output: 6
printf("%d", i++); // Output: 6, but i becomes 7
