Problem with While

  • 772

i am new to c++ language and i have a problem with this loop.

#include<iostream>
using namespace std;

int main(){
    int iterador=0;
    while (iterador<=10){
        cout<<iterador<<endl;
        iterador+=1;

    cout<<"si";

    }
}

It is supposed to print the numbers from 0 to 10 and then print something (I put "yes" to mislead) but when I run it, it prints it as follows:

0
si1
si2
si3
si4
si5
si6
si7
si8
si9
si1
si

and what I wanted was this!

0
1
2
3
4
5
6
7
8
9
1
si

Can someone explain to me why C++ does this, why it does this or how C++ works with loops?

Thank you!

  1. It is what Jesus says. I encourage you to try the following:

    for (int i = 0; i <= 10; ++i) cout << i << endl; cout << "Si" << endl;

    It's like a while but with fewer lines of code. What it comes to do is while the iterator that has been defined to 0 is less than or equal to the number that was marked, it increases the i and for each increase do what I indicate. In this case, display the iteration number on the screen.

    Everything inside your while will be executed every loop, try to get cout<<"if"; of the while

    #include<iostream>
using namespace std;

int main(){
int iterador=0;
 while (iterador<=10){
    cout<<iterador<<endl;
    iterador+=1;

  }
    cout<<"si";

}
