Answer 1

You need to tag JavaScript and code coach instead.

This problem "store manager" is very simple, you need to increase each items of the array. The following code will be helpful.

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for(var i=0;i<=prices.length-1;i++){
prices[i]=prices[i]+increase;
}
console.log(prices);
}

Answer 2

Why is there prices.length-1 and not just prices.length? What does it do? Im confused 🤷‍♀️ I know it makes it flexible in case adding a new price but in what way?

Answer 3

Justyna Dabrowska yes we can simply write price.length but loop should be

for(var i=0;i<prices.length;i++){}

Not

for(var i=0;i<=prices.length;i++){}

Simply condition part of the loop should be i<price.length

Answer 4

bruh thats all what you need
console.log(prices.map(x=>x+increase));

Answer 5

Simple way to solve :
function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
//var prices1=0;
for(var i=0;i<4;i++){
prices[i] = prices[i]+increase;

}
console.log(prices);

}

Answer 6

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for(var i=0;i<=prices.length-1;i++){
prices[i]=prices[i]+increase;
}
console.log(prices);
}

Answer 7

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for(var i=0;i<=prices.length-1;i++){
prices[i]=prices[i]+increase;
}
console.log(prices);
}

Answer 8

I cant remember [i] ever explained but ok

Answer 10

Puedes realizarlo usando el método map().

const increment = prices.map(e => e + increase);
console.log(increment);

Answer 11

# Use map function
console.log(prices.map((p) => {
return p+increase;
}))

Answer 12

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for (i=0; i < prices.length; i++) {
prices[i] += increase;
}
console.log(prices);
}

Answer 13

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//ваш код
array = [];

for(n=0; n<prices.length; n++){
array.push(prices[n] + increase);
}
console.log(array);
}

Answer 14

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
prices.forEach(inc => console.log (inc+increase))
}
why this is not passing the testcase even though its correct

Answer 15

Tried for a long time and finally had this one:

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
var newPrices = [];
for (let num of prices){
let pri = num += increase;
newPrices.push(pri);
}
console.log(newPrices)
}

Answer 16

function main() {
let increase = parseInt(readLine(), 10);
let prices = [98.99, 15.2, 20, 1026];
//your code goes here
for(i=0; i<prices.length; i++) {
prices[i] += increase;
}
console.log(prices);
}

Answer 17

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for(var i=0;i<=prices.length-1;i++){
prices[i]=prices[i]+increase;
}
console.log(prices);
}

Good Luck

Answer 18

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
for (var x = 0;x < prices.length;x++)
{
prices[x]= prices[x]+increase;
}
console.log(prices);
}

Answer 19

function main() {
var increase = parseInt(readLine(), 10);
var prices = [98.99, 15.2, 20, 1026];
//your code goes here
console.log("[ "+parseFloat(prices[0]+increase)+", "+parseFloat(prices[1]+increase)+", "+parseFloat(prices[2]+increase)+", "+parseFloat(prices[3]+increase)+" ]");

}

Answer 20

function main() {
var increase = parseInt(readLine(), 10);
