 Identify the errors in the following code segment and give the reason of errors.

main(){

int x = 10

const int *ptr = &x ;

*ptr = 5 ;

}

 

Ans:

      Int x=10….No ending semicolon.

*ptr=5 .. Declaring a pointer to constant integer.You can not use this pointer to change the value being pointed to.

   

 

Question No:     ( Marks: 3 )

  Can you use an assignment operator to assign the value of one C-string to another?

 

Ans:Yes,we use assignment operator,whenever we use objects that allocate memory it is important that assignment operator should be defined for it,otherwise default operator will copy the value of addressed and pointers.
