How to find min and max of int array in C

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h> 
  
int main(void)
{
    int arr[10], i, maxint, minint, size;
      
    size = sizeof(arr) / sizeof(int);  
 
    srand(time(NULL));  
     
    for (i = 0; i < size; i++) {
         arr[i] = rand() % 100 + 1;
         printf("arr[%d] = %d\n", i, arr[i]);
    }
             
    maxint = arr[0];
    minint = arr[0];
 
    for (i = 0; i < size; i++) {
         if (arr[i] > maxint) maxint = arr[i];
         if (arr[i] < minint) minint = arr[i];
    }
     
    printf("max = %d\n", maxint);
    printf("min = %d\n", minint);
 
    return 0;
}
