Difference Between C and C++ Programming

Difference Between C and C++ Programming

C Programming	C++ Programming
C follows the procedural programming paradigm	C++ is a multi-paradigm language(procedural as well as object oriented)
In C language focus on procedure and steps.	C++ focuses on the data rather than the process
In C data hiding and data security is not possible.	Data hiding and data security is present.
C uses Top-Down approch	C++ uses Bottom-Up approach
C is a function driven programming language	C++ is a object driven programming language
C does not support overloading concept	C++ supports overloading concepts like operator overloading and function overloading
C does not support namespaces concept	CPP supports Namespaces concept.
C not support exception handling	C++ supports Exception Handling
C is structured programming language	C++ is object oriented programming language.
C does not support inheritance, reusability, polymorphism, data abstraction	CPP supports inheritance, reusability, polymorphism, data abstraction.
C language only support Early binding	CPP supports both Early and Late binding
C uses standard input, output functions like scanf and printf.	C++ uses input function cin and output function is cout.
There are all data is available to end user. No data security	There is data abstraction. Not complete data is available to End user

C program for Binary Search

Hello, Today I am sharing how to implement Binary Search in C Programming 

language. Here is the basic algorithm for binary search:

C program for binary search :

#include<stdio.h>

int main(){

  int a[8];

  int i,x,first,last,mid;

printf("\nEnter 8 sorted elements like 

               [2 4 7 9 12 13 16 20]");

for(i=0;i<8;i++)

{

scanf("%d",&a[i]);

}

printf("\nYou entered following numbers:");

for(i=0;i<8;i++){

printf(" %d",a[i]);

}

printf("\nEnter the number you want to search: ");

scanf("%d",&x);

  

first=0,last=n-1;

while(first<=last){

      mid=(first+last)/2;

      

 if(x==a[mid]){

printf("\nThe number is found at %d", mid);

        return 0;

      }

      else if(x<a[mid]){

last=mid-1;

      }

      else

first=mid+1;

}

    printf("\nThe number is not in the list");

return 0;

}
