Write a while loop that prints 1 to userNum using the variab

Write a while loop that prints 1 to userNum, using the variable i. Follow each number (even the last one) by a space. Assume userNum is positive. Ex: userNum = 4 prints:

#include <iostream>
using namespace std;

int main() {
   int userNum = 0;
   int i = 0;

   userNum = 4;    // Assume positive

   /* Your solution goes here */

   cout << endl;

   return 0;
}

Solution

Please follow the code and comments for description :

CODE :

#include <iostream> // required header files

using namespace std;

int main() { // driver method
int i = 0; // required initialisations
int userNum = 0;

userNum = 4; //local variable to get the loop itearated
while(i < userNum) { // looping till the desired output gets printed
++i; // incrementing the value
cout << i << \" \"; // printing to the console
}
cout << endl; // new line character code
return 0;
}

OUTPUT :

1 2 3 4

Hope this is helpful.
