compiler errors - C - return value at index: control reaches end of non-void function -

first of all: started programming in c (my first programming language) , may stupid/simple question, trying implement function returns value @ index in array/list. error compiler: "error: compiler reaches end of non-void function" though returning values of type int. in advance:

int list_get(int list[], int length, int index) {   if(index <= capacity){      for(int = 0; <= capacity; i++){         if(i == index)             return list[i];      }   }   else{      printf("index out of range. \n");      return 0;   } } 

the compiler sees, both return statements under sort of conditional block, tries warn you. nothing wrong, such.

consider flow,

• index <= capacity true,
• for none of iterations, i == index true.
• for loop exited.

in case, there's nothing returned....

to avoid, move return 0; statement out of else block. aware of possible side effect, if i == index check fails, return 0.
