Question

#include <iostream>
using namespace std;

int main() {}

Write a program that produces a line comprised of n alternating a's and b's, where n is user-specified.

For example, the console content following a run of the completed program with an input of "5" is as follows:

Enter a number: 5 A line of length 5: ababa

Answer 1

Code:

#include<iostream>
using namespace std;
int main()
{
   int n;//Declaring a variable
   printf("Enter a number:");
   scanf("%d",&n);//Taking input from the user
   printf("A line of length %d :",n);
   for(int i=0;i<n;i++)
   {
       if(i%2==0) printf("a");//Printing a in place of even positions
       else printf("b");//Printing b in place of odd positions
   }
   return 0;
}
