Select the output for the following set of code?

the Correct answer

d) In elseIn main

correct answer (b) in esle

Answer: d

Explanation :Usage of ‘=’ operator instead of ‘==’ operator .hence,the condition is not true.

First of all the code written has some errors in it

Let's first clean the code.

• "int i =; "  :  this will throw error because u need to assign integer to the variable like int i = 0 or int i=1; etc;

• "int j=%;  "  : this will again throw error because u cannot assign percentage to integer. It has to be again something like this int j=1 or int j=2;

• "if (Convert.ToBoolean(convert.Toint(i=j))) " :   here int has to be converted to int16 , int 32 or int 64. 

• "if (Convert.ToBoolean(convert.Toint(i=j))) " : here i=j  condition willl not work because you will have to " ==" to compare two integers instead of "=".

Now suppose you assign :

• int i = 0;
• int j = 0;

the output result will be :

In If

In main

OR

if you assign :

• int i = 0;
• int j = 1;

the output result will be :

In else

In main

Note : Here, In main will render in all situation because it is written out of if else condition.

The program is messed up:

int i =; is an invalid expression. A value must be assigned.

int j=%; is also an invalid expression. Again a value must be assigned.

toInt = Convert fn. does not contain definition of toInt.

Comparison operator equality is "==" instead of "="

The values of i and j are invalid. they are integers. plus your equality condition is wrong (==).

However, if i == j then the answer would be b)

otherwise it's d)

There two things with this program:

1. There are some errors for e.g int i=; int j=%; are wrong statements and compiler will generate compile time error. variables of data type int must be initialized properly by providing some value say int i=0, int j=2; etc.2. The calls to functions Convert.ToBoolean and Convert.ToInt are redundant. Convert.ToInt is normaly used to convert non-int types to int. similarly Convert.ToBoolean is used to convert non-boolean types to boolean. By analyzing the program these two calls are redundant as they main purpose is to check if i==j or not. so replace simply by if(i==j) that will do the same as both variables have same type.

For instance if we ignore compilation issues, following is the output

(d) In else

In main

The  program is Right and Working 

int i =; which is invalid expression

int j=%; invalid expression

toInt = convert does not contain defination of toInt.

comparison operator equality is == instead of =
