c - Why strings are permitted while arrays are not in this code? -

#include<stdio.h> void function1(){} int main(void) {   function1(1,0.45,'b',"i trying");   function1();   return 0; }

this compiles nicely. below showing

error: use arr in function1 first....

note using code::blocks ide , saved file .c extension.

#include<stdio.h> void function1(){} int main(void) {    function1(1,0.45,'b',"i trying",arr[12]);    function1();    return 0; }

sorry made mistake calling array. {1,2,3,4} array agree ..but not work. bug or ?

in second case,

 function1(1,0.45,'b',"i trying",arr[12]);

arr[12] variable, , arr not defined, least being array.

in c, need define variable before using it.

fwiw,

function1(1,0.45,'b',"i trying");

works, because

and none of them variable.
