Let's understand this by going through the following code

#include<stdio.h>
int f1();
int f2();

void main()
 {
 printf("%dt%d",f1(),f2());
}

int f1()
{
 printf("f1() enteredn");
 return 4;
}

int f2()
{
 printf("f2() enteredn");
 return 5;
}

O/P-

f2() entered
f1() entered
4        5

we can conclude f2() is 1st executed
then f1() and in the end printf().hence we can say the precedence of execution of functions are from right to left.

Q. Difference between "C structure" and "C++ structure".
Ans:- C structure cannot have member functions but C++ structure can have. Also in a C structure by default all data members of structure are public and access cannot be changed by specifying the private or protected keywords but in C++ eventhough by default members are public we may change the access using the keywords private and protected.
Q. What is the difference between "overloading" and "overridding"?
ans:- Overloading is a process of having the same function name but different no of arguments or types of arguments within the same class but overriding means redefining a baseclass functions definition in the subclass.
Q. Explain the need for "Virtual Destructor".
Ans:=Virtual destructor ensures destruction of subclass and base class objects in proper order.
Q. What are the different types of polymorphism?
Ans:-Overloading and overriding.
Q. What are the different types of Storage classes?
ans:-Auto,Register,static and extern
Q. What is the difference between "calloc" and "malloc"?
Ans:- calloc and malloc are used for dynamic memory allocation. Calloc initializes the memory locations to zero by default but malloc memory contains garbage values.
Difference between "printf" and "sprintf".
printf will write to the console. sprintf will write to the buffer

An lvalue is an expression to which a value can be assigned. The lvalue expression is located on the left side of an assignment statement, whereas an rvalue is located on the right side of an assignment statement. Each assignment statement must have an lvalue and an rvalue. The lvalue expression must reference a storable variable in memory. It cannot be a constant.
