C Program for Maximum and Minimun number in an One-Dimensional Array

The below code will find the maximum and minimum numbers in an array.

Logic: Use linear search to search for the max and min numbers.

Code:

#include <stdio.h>
#include <conio.h>  

void main()
{
   int i,size,max,min;

  //get the size of the array  

   printf("Welcome\nEnter the total number of elements(numbers):");
   scanf("%d",&size);
   
  //declare an array

  int numbers[size];
  
  //take input , to fill the array.
  
  printf("Enter numbers");
  for(i=0;i<size;i++)
  {
     scanf("%d",&numbers[i];
   }

 /*to calculate maximum and minimum,these variables need to be initialized with some data,therefore we initialize it with the first elements of the array*/

  max=numbers[0];
  min=numbers[0];

 //use linear search to find the max and min number of the array

//star from index 1 as min and max are already initialized with the element at index o
 for(i=1;i<size;i++) 
 {
    //if the number at index i is greater then the number in max then put the number at i in max
 
    if(max<numbers[i])
           max=numbers[i];
    
    //if the number at index i is less then the number in min then put the number at i in min
    if(min>numbers[i])
           min=numbers[i];
 }

 //print the max and min numbers

 printf("\nMax is %d\nMin is %d",max,min);

 printf("\npress any key to continue");
 getch();

}
