While loops

Question

Still not able to understand, Please help!!!
//c++

#include <iostream>
using namespace std;

int main()
{
int num = 1;
int number;
int total = 0;

while (num <= 5) {
cin >> number;
total += number;
num++;
}
cout << total << endl;

return 0;
}

Answer 1

while value of num variable is less than or equal to 5 it will take input from and store it in number variable.
Thenafter value of number will be added with value of total variable and num is incremented by 1(num++)
It will result in output when while loop complete its execution that is when num got value greater than 5

Answer 2

while num is < 5 or =5
get a new number
add it to total
num= num+1

Answer 3

which part

Answer 4

thanks for quick response,

but i m still confused

Answer 5

finally i understood this;

#include <iostream>
using namespace std;

int main() {
int num = 1;
int number;
int total = 0;

while(num<=5){
cin >> number;
total+=number;
cout << "Total = " << total << endl;
num++;
}
return 0;
}

======================================

basically this will happen inside it

total + number = total

( if number is 3)
then

0 + 3= 3
3+ 3 =6
6+3=9
9+3=12
12+3=15
(calculation will continue till num value equals 5)

final total will be 15

======================================

and i thought this should happen,

num=num+1

3+1=4
4+1=5
5+1=6
6+1=7
7+1=8

total = 8

😅 just got confused between num and number
