| Sr. No. | Key | C | C++ |
|---|---|---|---|
| 1 | Introduction | C was developed by Dennis Ritchie in around 1969 at AT&T Bell Labs. | C++ was developed by Bjarne Stroustrup in 1979. |
| 2 | Language Type | As mentioned before C is procedural programming. | On the other hand, C++ supports both procedural and object-oriented programming paradigms. |
| 3 | OOPs feature Support | As C does not support the OOPs concept so it has no support for polymorphism, encapsulation, and inheritance. | C++ has support for polymorphism, encapsulation, and inheritance as it is being an object-oriented programming language |
| 4 | Data Security | As C does not support encapsulation so data behave as a free entity and can be manipulated by outside code. | On another hand in the case of C++ encapsulation hides the data to ensure that data structures and operators are used as intended. |
| 5 | Driven type | C in general known as function-driven language. | On the other hand, C++ is known as object driven language. |
| 6 | Feature supported | C does not support function and operator overloading also do not have namespace feature and reference variable functionality. | On the other hand, C++ supports both function and operator overloading also have namespace feature and reference variable functionality. |

#include <iostream>
using namespace std;
bool isNumber(string s)
{
for (int i = 0; i < s.length(); i++)
if (isdigit(s[i]) == false)
return false;
return true;
}
// Driver code
int main()
{
// Saving the input in a string
string str = "6790";
// Function returns 1 if all elements
// are in range '0-9'
if (isNumber(str))
cout << "Integer";
// Function returns 0 if the input is
// not an integer
else
cout << "String";
}
