Create a program that takes two numbers - one to count to and another to determine what multiple to use to get there.
Here is some sample input:
Count to: 30 Count by: 5 Output: 5, 10, 15, 20, 25, 30
Count to: 50 Count by: 7 Output: 7, 14, 21, 28, 35, 42, 49
here is my trial code.
var num1 = parseInt(prompt("Count to: "));
var num2 = parseInt(prompt("Count by: "));
for(let i = num2; i <= num1; i+num2){
}
console.log(i);You need to increase the value of i in your loop as i+num does not increase its value:
// Changed the variable names to something more descriptive
// to avoid confusion on larger code bases;
var maxValue = parseInt(prompt("Count to: "));
var stepValue = parseInt(prompt("Count by: "));
// Can also be written as index += stepValue
for(let index = stepValue; index <= maxValue; index = index + stepValue) {
// Print the current value of index
console.log(index);
}Below snippet could help you
function count(countTo, countBy) {
const arr = []
for (let i = countBy; i <= countTo; i += countBy) {
arr.push(i)
}
console.log(arr.join(', '))
}
count(30, 5)
count(50, 7)
Use modulus operator in your loop with a conditional that checks if the modulus of the number iterated is equal to zero...
Count to: 30 Count by: 5 Output: 5, 10, 15, 20, 25, 30
let targetNumber = 30;
for(let i = 1; i <= targetNumber; i++){
if( i % 5 === 0){
console.log(i)
}
}Count to: 50 Count by: 7 Output: 7, 14, 21, 28, 35, 42, 49
let targetNumber = 50;
for(let i = 1; i <= targetNumber; i++){
if( i % 7 === 0){
console.log(i)
}
}Your setup was good, only the console.log statement needs to be inside the loop to print.
var num1 = parseInt(prompt("Count to: "));
var num2 = parseInt(prompt("Count by: "));
for (let i = num2; i <= num1; i += num2) {
console.log(i);
}
i+num2->i += num2console.log(i)needs to be inside the loop.
