C language limitations

Question

What are the limitations of C language compared to other programming languages?

Solution

• The C language blocks or prohibits concepts from object-oriented programming languages ​​such as inheritance, polymorphism, encapsulation, and data abstraction.

• The C programming language does not do error checking on every line of code, it checks for errors after completing the entire coding.

• It does not have the namespace attribute.

• C programming is insufficient in data abstraction, that is, it does not have very large data processing capabilities.

• C language does not allow users to detect errors through exception handling functions.

• C language does not support the concepts of constructors and destructors.

• Compared to other programming languages, it does not fully support solving real-world problems.

• It is less secure compared to other programming languages.

Basic Structure

The following is the general structure of a "C" program:

/* documentation section */
preprocessor directives
global declaration
main ( ){
   local declaration
   executable statements
}
return type function name (argument list){
   local declaration
   executable statements
}

Example

/* Author : Tutorialspoint
Aim : Program for finding circumference of circle*/
#include<stdio.h>
#include<conio.h>
#define PI 3.1415
main ( ){
   float c, r;
   clrscr ( );
   printf ("enter radius of circle");
   scanf ("%f", &r);
   c = 2 * PI * r;
   printf ("Circumference = %f", c);
   getch ( );
}

Output

Enter radius of circle r=4
Circumference of circle c=25.132000
