how we can define and use structure inside function in C?

Question

I am trying to create a structure inside a function and i am trying to use it. But when I am comparing two values from structure I am getting this message :

"C:\\Users\\hp\\Desktop\\prgm\\cap.c||In function 'fnumber':| C:\\Users\\hp\\Desktop\\prgm\\cap.c|

72|error: request for member 'f_value' in something not a structure or union| ||=== Build failed: 1 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

this is my code:-

#include <math.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>
#include <limits.h>
#include <stdbool.h>

/*
 * Complete the function below.
*/
int fnumber(long input1,int input2_size, int* input2)

    int i, j, k, count[input2_size],temp=0;
    int arr_temp[input2_size];
    struct smaller{
            int position;
            int f_value;};

     struct smaller list[input2_size];
     struct smaller temp1;
    memccpy(arr_temp, input2, input2_size,sizeof(int));

Answer 1

        if(list[i].f_value>list[j.f_value])

You misspelled list[j].f_value as list[j.f_value] .

Also, memccpy should be memcpy .
