Difference between Compile Time Errors and Runtime Errors in C Program

C Server Side Programming Programming

Error or exception is something that refers to the interruption of code execution due to which the expected outcome could not be attained to the end-user.On the basis of the event when an error is generated or identified we can classify them as Compile time error and runtime error.

The following are the important differences between Compile Time Errors and Runtime Errors.

Sr. No.	Key	Compile Time Errors	Runtime Errors
1	Reference	Compile-time errors are generally referred to the error corresponding to syntax or semantics.	Runtime errors on the other hand refer to the error encountered during the execution of code at runtime.
2	Detection	Compile-time errors get detected by compiler at the time of code development.	Runtime time errors are not get detected by compiler and hence identified at the time of code execution.
3	Fixation	Compile-time errors as already mentioned can get fixed at the time of code development.	Runtime time errors are getting to fixing state after once code get executed and errors get identified.

Example of Compile time errors vs Runtime time errors

CompileDemo.c

#include<stdio.h>
public class CompileDemo{
   void main(){
      int x = 100;
      int y = 155;
      // semicolon missed
      printf("%d", (x, y))
   }
}

Output

error: expected ';' before '}' token

Example

RuntimeDemo.c

include<stdio.h>
public class RuntimeDemo{
   void main(){
      int n = 9;
      div = 0;
      div = n/0;
      printf("resut = %d", div);
   }
}

Output

warning: division by zero [-Wdiv-by-zero]
div = n/0;
