Answer 1

Answer

Let consider the rollnumber as 135, so sum of 1 and 3 is 4 , ie  $\beta$ =4 .

so giving  $\beta$ value as 4 in the code we get the output

Enter Student Name: Jhon Enter Student Age: 19 Enter Student Roll number: 135 Student class year: CS2020 Age Age Age Age 19 Name Name Name Name Jhon R.no. R.no. R.no. class class class class CS2020 R.no. 135

Here for loop will print Age Name R.no Class  $\beta$ times. So if no change is possible to the code , the above output will be correct .

In my opinion , this for loop is not needed in this code , which makes the output wrong , so after removing it we will get the below output

Enter Student Name: Jhon Enter Student Age: 19 Enter Student Roll number: 135 Student class year: CS2020 Age 19 Name Jhon R.no. 135 class CS2020
