What is difference compiling error and runtime error

Question

And give example

Answer 1

A compile error happens when you try to compile or build a project/code but it fails.

Runtime error occurs AFTER you compiled/build the project and you were clicky on buttons on your application and suddenly it crashes.

Example: (any OOP lang)
Compile error

int x = 0 //no semi colon

Runtime:

public void sumthing(){
Int[] x = new {1, 2};
//Error will only occur when you call this function
//Also, its out of bound index error.
int y = x[3];
}

Answer 2

Compiler time errors occur before the code is executed. When a computer begins to compile your code, it turns the high-level language you wrote into machine code. If it cannot properly translate your code into machine code, you receive a compiler-time error.

For example, if I write something that has incorrect syntax, I will get a compiler time error:

string test = "hello; <---- No closing quotation mark (Compiler-time error)

Runtime errors occur after the code has been compiler and is running. If something unexpected occurs you get a runtime error:

int a = 3;
for(int i=0; i<10; i++){
cout << a/i << endl; <---- Divide by zero (Run-time error)
}
