1. What is the main difference between c and c++ ?
| C | C++ |
|---|---|
| C is a structured programming language. | C++ is an object oriented programming language. |
| C language is not in solving the real time problem. | C++ works well in solving real time problem. |
| Polymorphism is not possible. | Polymorphism is used in C++. |
| In C, malloc() and calloc() Functions are used for Memory Allocation and free() function for memory Deallocating. |
C++, new and delete operators are used for Memory Allocating and Deallocating. |
| Operator overloading is not possible in C. | Operator overloading is one of the greatest Feature of C++. |
| No namespace Feature is present in C Language. | Namespace Feature is present in C++ for avoiding Name collision. |
| scanf() function used for input and printf() function used for output. |
Cin function used for input and Cout funtion used for output. |
| Polymorphism, Operator Overloading Concept is not possible in C. |
Polymorphism, Operator Overloading Concept is the most important feature in C++. |
| C requires all the variables to be defined at the starting of a scope. |
C++ allows the declaration of variable anywhere in the scope i.e at time of its First use. |
| Exception Handling is not present in C. | Exception Handling is done with Try and Catch block. |
