In C language, _Noreturn function specifier

_Noreturn The function specifier tells the compiler that the function will not return anything. If some return statements are used inside the program, the compiler will generate a compile-time error.

Sample Code

#include<stdio.h>
main() {
   printf("The returned value: %d</p><p>", function);
}
char function() {
   return &#39;T&#39;; //return T as character
}

Output

The program terminates abnormally
[Warning] function declared 'noreturn' has a 'return' statement

Now if it is a normal function it will work fine.

Sample code

#include<stdio.h>
int function() {
   return 86; //try to return a value
}
main() {
   printf("The returned value: %d</p><p>", function());
}

Output

The returned value: 86
