Hey! :smile: I have a checkbox with radio button and I want that a popup message is shown if we have selected the second option. I tried to do that with if statement but it doesn't work. How do we write the if statement in React? Isn't it 'condition ? true : false' ? Do we not check if the...

Line 7 in the code below seems to remove an element from stack, but why is this happening since it's just checking a condition? I'm pretty shocked I don't have to remove the previous char from stack myself. def isValid(s): stack = [] dict = {"]":"[", "}":"{", ")":"("} for char in s...

So I used this statement, if (call_time > 0 && call_time <= 6.59) where the variable was declared as float. What is strange is that it didn't execute for call_time = 6.59, but for some other values, like if (call_time > 0 && call_time <= 2.59) the end value of the range does not cause any...

Goal: I'm trying to allow the user to input varying spellings for certain auto services, and still have my code work properly. My goal was to use the if-else statements to ensure that if the user misspelled a service, the code could correct the error by changing the variable assignment to the...

Hello, I am writing a program on Fortran to calculate the integral of sin^4(x) between x = 0 and x = π/2. I believe I know how to write the correct code, but I am unsure what the if statement should be for whether or not a point is inside the desired area. Any thoughts? Thanks.

I have a Do loop running which, for some values will become complex, and I want to make it so for these situations, we take the negative root and for others the positive root. In this scenario, I've simplified what I actually have and chose to look at the case where I need it to take the...

I have run into an if statement as shown below: if (randoms[(x * 3) + y] % 2) I don't really understand what this means. Thank you for helping!

Currently in my C++ program I have something like if (A){ do thing 1; } if (A && B){ do things 1 and 2; } if (A && B && C){ do things 1 and 2 and 3; } and so on. Unfortunately this has to be done for a very large sample and it takes quite a long time. I was just wondering if it's more...

Hi, so I'm trying to use the following if statement: if (sum(i,j) <=1.0 ) then sidash=(si)*(Death) else if (1 <= sum(i,j) <= 2) then sidash=(si)*((sqrt(2.0)+1.0)*(2.0-sum(i,j))*(Death)+(sum(i,j)-1.0)*(Survive)) else if (sum(i,j)<=3 .and. sum(i,j)=>2) then...

I am reading an input file that has blank lines. x reads character by character. x is equal to a new line so it goes into the while loop but skips the if x == '\n'. It's suppose to go inside the if statement but it doesn't. I tried debugging the code and printed out to double check x is holding...

quick question, not sure why i can't work this out. in the following code my if statement executes, but as far as i can see i have set the boolean so that it shouldnt. public void actionPerformed(ActionEvent e) { boolean contains = false...

I don't understand why this would work, shouldn't it be "while(x)" because we don't want to repeat the loop? int main(void) { int x=0; do { printf("Enter an amount:\n"); scanf("%lf", &amount); if (amount < 100) x=1; else printf("Invalid"); }while(!x); return 0; }

Homework Statement A sequence (Xn) is Cauchy if and only if, for every ε>0, there exists an open interval length ε that contains all except for finitely many terms of (Xn). Homework Equations The Cauchy Definition is: A sequence X = (xn) of real numbers is said to be a Cauchy sequence...

So i am writing a Verilog program for a combination lock. I am using a state machine format to write it. I have commented out everything and just isolated one if statement as you can see. No matter what i put in the if statements the code within it (next_state = Inuse;) activates. The only way i...

Im Having trouble writing an if statement with the time variable of the ode45 function. I don't know if i need to create a new variable, which is not what i want, but just to create and if statement with the t variable from ODEs. Hope someone knows how to solve this problem Thank you

Java help ! (how to not to use if statement) My teacher asked the user for an integer and converted it into a number in base N, where N was a value between 2 and 9, inclusive. Expand this program to allow values of N between 2 and 36, inclusive, where digits representing the numbers 10, 11...

I am learning VBA for Excel and Am just wondering what is wrong with the logic in this statement? Note that at the present moment, Time < 0.5 , but my program is outputting "Good Evening" Sub Better_Nested_If() Dim Msg As String If Time < 0.5 Then Msg = "Mornin'" Else...

Regression in Excel I want to make an regression of some data, but I only want to use some of the data. The data I want use is where Vacant = 1. Is this possible in excel? I have tried to use the if-function but the regression does not like "false" More info I want to make a...

Hi there, I've tried all I could in order to complete a very simple and basic program that finds the roots of any quadratic binomial. You have to enter the coefficients a, b and c and it would find the roots. I could do that, but a problem occurred if I typed a=0. Of course if a=0 the...

N is the same as Kg/m/s^2. False...K.g/M/s^2.? It is easier to sweep with a brown if your hand is further up on the handle. true? a screw with fewer threads is easier to use than a screw of the same size with more threads.-true? water at 4^0C is lighter than at 4.1^0C. True? ice can...

Howdy, tonight I was playing around with trying to pass a value from a form field and use it for an "if" statement in php. the html: <HTML> <HEAD> <TITLE>Form Test</TITLE> </HEAD> <BODY> <H1>Form Test</H1> <form name="input" action="myscript.php" method="get"> Enter a 1 or a 2...

I feel silly asking this but I can't get my "If" statement to work correctly. This should print "a is NOT equal to b" but it prints "a is equal to b". Any help? Thanks! #include <stdio.h> int main(void) { int a = 10; int b = 15; if(a == b) printf("a is equal...
