range - C Program will not calculate min and max (large and small) -

i cannot seem figure out why not getting correct values large , small. supposed find range of n numbers given, have set large , small before loop?

here code:

#include <stdio.h>  int main() {     //declaring variables     int i, number, sum = 0, value, large, small;     double avg;              //user input             printf("enter number of elements want compute.\n");             scanf("%d", &number);             printf("enter %d values.\n", number);              //loop grab values             for(i=0;i<number;i++)             {                     scanf("%d", &value);                     large = value;                     small = value;                     if(value > large)                             large = value;                     if(value < small)                             small = value;                     //sum calculation                     sum = sum + value;                     //average calculation                     avg = (((double)sum)/number);             }              printf("the sum of %d numbers is: %d\n", number,sum);             printf("the avg of %d numbers is: %.2f\n", number, avg);             printf("the largest number is: %d\n", large);             printf("the smallest number is: %d\n", small);      return 0; } 

                large = value;                 small = value;                 // point                 if(value > large)                         large = value;                 if(value < small)                         small = value; 

at point above, large, small, , value contain same value. subsequent if statements won't ever take effect. wanted first 2 lines when i == 0.
