This method is quick and clean, basically read in values the number of times specified, and each time the number is greater than the current maximum, replace max with the value read. int main() { int num_entries; float num; float max = 0; cin >> num_entries; while (num_entries– > 0){ cin >> num; if (num … Read more
The line World(height, width); constructs a temporary object and discards it. The member variable of the current object never get initialized properly. Simplify your code. Move the code to get input data to the function that calls it. For example, use it in main. int width = -1; int height = -1; cout << “Aby … Read more

A better approach is to use a while loop to collect input, and only exit the while loop after receiving valid data. num1 = 0 while num1 == 0: value = input(…. if ValidateInput(value): num1 = value num2 = 0 while num2 == 0: value = input(…. if ValidateInput(value): num2 = value # do other … Read more
Here is a snippet with two input boxes: the top one defining the replacement rules and the bottom one accepting any text input to be processed: function mkdict(){ dict={}; key.value.split(“,”).forEach(kv=>{ let [k,v]=kv.split(“=”); dict[k]=v; }); transform(); } function transform(){ out.textContent=text.value.split(“”).map(c=>dict[c]||c).join(“”); } var dict; mkdict(); key.addEventListener(“input”,mkdict); text.addEventListener(“input”,transform); <input type=”text” value=”i=!,t=7″ id=”key”><br> <input type=”text” id=”text”> <div id=”out”></div> For … Read more

I’m struggling whether to vote to close this as a duplicate, even though it’s not exact. But what you’re looking for appears to be answered here. The main difference is that where they are binding to the change event for a select element: $(“#selectBox”).change(function() { you would instead bind to the click event of an … Read more
Use prompt like so: var number1 = parseInt(prompt(“Enter a number”)); var number2 = parseInt(prompt(“Enter another number”)); document.write(`${number1} + ${number2} = ${number1 + number2}<br>${number1} * ${number2} = ${number1 * number2}`); solved How to get user input and output it onto the web page [closed]
In modern browsers (and IE8), you can use document.querySelector to use any CSS selector to find an element. In your case, for instance, you could use var x = document.querySelector(‘[action=”form_action.asp”]’); …to look it up by the value of its action attribute. The rest of your function doesn’t change. querySelector finds the first matching element. If … Read more
To create a specific number of objects and store them somewhere you can easily use arrays: Scanner[] scanners = new Scanner[num_of_scanners]; At this point you will have an array of null scanner objects. To declare them properly you have to use a loop like this: for (int i = 0; i < scanners.length; i++) { … Read more
You can use the String.fromCharCode feature. For example: let myChar=”c”; let nextChar = String.fromCharCode(myChar.charCodeAt(0)+1); console.log(nextChar) // ‘d’ In your case, you would replace ‘c’ with your character variable. 0 solved Finding a faster way of checking characters in js [closed]
