Question

Define a function to find the largest element from an integer array.

Answer 1

PROGRAMS ARE DONE WITH C,C++,JAVA AND PYTHON PROGRAMMING LANGUAGE

HERE THE FULL PROGRAM WITH FUNCTION DEFINITION IS SOLVED.

PROGRAM WITH C

#include<stdio.h>
/* define function large_array to find largest element of the array */
/* it has two parameters arary content and array length */
int large_array(int arr[],int n)
{
   int i=0,m=0;
   /* traverse the array */
   for(i=0;i<n;i++)
   {
       if(m<arr[i])
       {
           m=arr[i];
       }
   }
   /* return largest element */
   return m;
}
int main()
{
   /* arr is array of integers */
   int arr[100],n,i,lrg;
   /* console input number of values */
   printf("How many elements : ");
   scanf("%d",&n);
   /* console input values of array*/
   printf("\nEnter the elements\n");
   for(i=0;i<n;i++)
   {
       scanf("%d",&arr[i]);
   }
   /* large_array function called and returned value stored in lrg */
   lrg=large_array(arr,n);
   /* print lrg */
   printf("\nLargest element is : %d ",lrg);
   return 0;
}

PROGRAM WITH PYTHON ( IF ANY PROBLEM FACED IN INDENTATION KINDLY FOLLOW THE BELOW SCREEN SHOT. IT IS IN IMAGE FORMAT , SO INDENTATION IS ACCURATE, HERE IN PYTHON IN PLACE OF ARRAY LIST IS TAKEN )

#define function large_array to find largest element of the list
# it has two parameters list content and list length
def largest_array(arr,n):
max=0
for i in range(0,n):
if(arr[i]>max):
max=arr[i]
# return max
return max
  
  
  
#initialize the list
lst=[]
#console input number of values
n=int(input('How many elements : '))
#console input values of list
print('Enter elements ')
for i in range (0,n):
val=int(input())
lst.insert(i,val)
#large_array function called and returned value stored in lrg
lrg= largest_array(lst,n)
# print lrg
print('Largest element is : ', lrg)
