The NULL pointer is a constant with a value of zero defined in several standard libraries. The parameters sent to the function at calling end are called as actual parameters while at the receiving of the function definition called as formal parameters.
If a variable is used most frequently then it should be declared using register storage specifier, then possibly the compiler gives CPU register for its storage to speed up the look up of the variable. The reason for this is that each time p1 is incremented, it will point to the next integer.
Now the most important thing is that you skip those topics or question that you think are unnecessary and unimportant from exam point of view.
In multilevel inheritance, the derived class becomes the base of another class. The scope resolution operator is used to Resolve the scope of global variables.
Declaration associates type to the variable whereas definition gives the value to the variable. A variable whose scope is applicable only within a block is said so. It also stores the current state of the CPU.
Many students tend to concentrate more on books which have been published by private publishers and less on the books which have been published by NCERT National Council of Educational Research and Training. What is the purpose of undef preprocessor. No, it contains invalid octal digits.
What is a default constructor. The amount of memory to be allocated is known in advance and it allocated during compilation, it is referred to as Static Memory Allocation. You can subtract one pointer from another in order to find the number of objects of their base type that separate the two.
Right now the board exams are approaching and you need to be prepared for them.
So just feel confident during your interview. A virtual function with no function body and assigned with a value zero is called as pure virtual function. What is a preprocessor. A constructor is the member function of the class which is having the same as the class name and gets executed automatically as soon as the object for the respective class is created.
The only difference between pointers of different data types is the data type of the variable or constant that the pointer points to. What is an inline function. Hence avoiding compiler optimization on the variable reference.
