In the code below the output is 2. This code is used in a challenge and I get an error when I select the answer 2. It accepts as correct the answer 1 which I believe is wrong. If you agree please thumbs up.
If you find any other errors please post them here!
#include <iostream>
using namespace std;
int main()
{
for(int i=1; i>=1; i++) {
if(i<1 || i>1){
cout << i;
break;
}
}
return 0;
}

Python provides an inbuilt function 'print' which h automatically generates a line break when it is called, then how can we generate a pattern as :
1
2 2
3 3 3
4 4 4 4
and so on..
using while loop ???

0+1
1+2
3+3
6+4
10+5

and maybe if it works, can i make then
0+1=1
1+2=3
3+3=6
6+4=10

Can anyone help me to code this
Write a method 'timesTable()' which accepts an integer value num from the keyboard and uses it to print 'times table' of itself in a structured format. Your output must include a header row. For example, if the user enters 5, your program's output should be:
5 Times Table
1 5 5
2 5 10
3 5 15
4 5 20
5 5 25
6 5 30

Hmm. But in the case we delete a row (toghether with the ID) there will be a gap between the sequence of the ID's. Does auto_increment fill that gap when a new user is created, or will it just add 1 to the last id in the table?

x = 42;
int num = 0;
while (num <3)
Consele.writeline (x);
num++;
int x = 42; is just an int with an asigned value of 42
int num=0; is what initiate the count for the while loop
while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false
consele.writeline (x) will display 42 while num < 3
num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false.
so the consele.write will write 42 three times. x=42, remember the (x)

2 Respostascan someone tell me how to make it impossible for a user to type a 'userchoice1[x]' value that does not range from 1 - 10.
If you also know a way I can make the user input another value for the 'userchoice1[x]' variable if it is less than 1, I'll appreciate you share the knowledge with me.
please see the short code below

Assign each track runner a roster number and calculate the average age of the team.
As output the program should print the roster in three columns like in the following format:
Roster # Name Age
1 First Name 18
2 Second Name 19
3 Third Name 19
4 Fourth Name 20
5 Fifth Name 18
The average age of the team is 18.80.

1 Respostaso far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.
