Shorthand for if-else statement
Using the ternary 😕 operator [spec]. var hasName = (name === ‘true’) ? ‘Y’ :’N’; The ternary operator lets us write shorthand if..else statements exactly like you want. It looks like: (name === ‘true’) – our condition ? – the ternary operator itself ‘Y’ – the result if the condition evaluates to true ‘N’ – … Read more
How to specify multiple conditions in an ‘if’ statement in JavaScript [closed]
Just add them within the main bracket of the if statement like: if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == ”)) { PageCount = document.getElementById(‘<%=hfPageCount.ClientID %>’).value; } Logically, this can be rewritten in a better way too! This has exactly the same meaning: if (Type == 2 && … Read more
Too many ‘if’ statements?
If you cannot come up with a formula, you can use a table for such a limited number of outcomes: final int[][] result = new int[][] { { 0, 0, 1, 2 }, { 0, 0, 2, 1 }, { 2, 1, 3, 3 }, { 1, 2, 3, 3 } }; return result[one][two];
New containing div after every 3 records
As tadman stated in the comment under your question. The best approach should use a modulus operator (%) with 3. Place your separating condition at the start of each iteration. (Demo) Like this: $x=0; // I prefer to increment starting from zero. // This way I can use the same method inside a foreach loop … Read more
How is if/while condition evaluated when we use assignments instead of comparison?
= is assignment operator, == is comparison operator. But assignment operator x = y not only assigns value from y to variable x, but it also returns that value. Thanks to that we can write code like x = y = z = 1; //equivalent of: x = (y = (z = 1)); (although it … Read more
Compound condition in C: if (0.0 < a < 1.0)
Because of left-to-right associativity of < operator the expression condition (0.0 < a < 1.0) means ((0.0 < a) < 1.0) == 1 < 1.0 or 0 < 1.0 depending on value of a. So no, its not identical to if (0.0 < a && a < 1.0) (perhaps you might confusing from Python compassion … Read more
Why does this if condition fail for comparison of negative and positive integers [duplicate]
The problem is in your comparison: if ((-1) < SIZE) sizeof typically returns an unsigned long, so SIZE will be unsigned long, whereas -1 is just an int. The rules for promotion in C and related languages mean that -1 will be converted to size_t before the comparison, so -1 will become a very large … Read more
I got “scheme application not a procedure” in the last recursive calling of a function
You intend to execute two expressions inside the consequent part of the if, but if only allows one expression in the consequent and one in the alternative. Surrounding both expressions between parenthesis (as you did) won’t work: the resulting expression will be evaluated as a function application of the first expression with the second expression … Read more
