Question

a) Find a bug in the code snippet below. Assume that a, b, c and d are correctly declared and initialized integer variables.

a = b+c
if (a=d) then

  print *,”A equals to D”
else

  print *,”A does not equal D”
end if

b) Find a bug in the code snippet below. Assume that a,b,and c are correctly declared and initialized integer variables.

if (a+b) > c) then
  print *,”Sum of A+B is greater than C”

end if

Answer 1

Answer a:

Bug in code a is inside the if statement, For checking the condition to be equal using if statement we should us "==" for comparison inside the if statement,

So, instead of if (a=d) the correct statement should be if(a==d).

C++ bug free code for question a is:

#include<bits/stdc++.h>

using namespace std;

int main()

{

int a,b,c,d;

cout<<"enter the value of b,c,d"<<endl;

cin>>b>>c>>d;

a = b+c;

if(a==d)

{

cout<<"A equals to D";

}

else

{

cout<<"A does not equal D";

}

return 0;

}

Output screen:

Answer b:

Bug in the code b is inside the if condition, their is opening bracket missing of the condition.

Instead of if(a+b)>c) the statement should be if((a+b)>c).

C++ bug free code for question b is:

#include<bits/stdc++.h>

using namespace std;

int main()

{

int a,b,c;

cout<<"enter the value of a,b,c"<<endl;

cin>>a>>b>>c;

if((a+b)>c)

{

cout<<"Sum of A+B is greater than C";

}

return 0;

}
