Prerequisites

Before starting with this tutorial we assume that you are best aware of the following C programming topics:

Operators in C Programming.

Basic Input and Output function in C Programming.
Basic C programming.
For loop in C Programming.

Creating and Using the user-defined function in C programming.

The Maximum value of array:-

As we all know array is a collection of similar data type elements. In an array, only one variable is declared which can store multiple values. The index value of the array start’s from “0” if the array is having size 5 i.e. a[5] = { 1, 2, 3, 4, 5 } values can be stored in that array. Now the a[0] = 1 , a[1] = 2, a[2] = 3, a[3] = 4, a[4] = 5. On the array, we can do many operations with the help of the c language.

We will find the maximum size element with the help of conditional statements.

Algorithm:-

STEP 1: START

STEP 2: INITIALIZE array

STEP 3: take input array size

STEP 4: take input array elements

STEP 5: check using statements

STEP 6: PRINT "Largest element present in given array:" 

STEP 7: RETURN 0.

STEP 8: END.

STEP 1: START

STEP 2: INITIALIZE array

STEP 3: take input array size

STEP 4: take input array elements

STEP 5: check using statements

STEP 6: PRINT "Largest element present in given array:"

STEP 7: RETURN 0.

STEP 8: END.

Program:-

To find the Maximum value element from the array

#include <stdio.h>
int main() 
{
  //declaring variables.
  int no;
  double arr[100];
  //Taking input size of array 
  printf("Enter the number of elements between 1 to 100): ");
  scanf("%d", &no);
  //any numner input
  for (int i = 0; i < no; ++i) {
    printf("Enter element %d: ", i + 1);
    scanf("%lf", &arr[i]);
  }
  // storing the largest number to arr[0]
  for (int i = 1; i < no; ++i) {
    if (arr[0] < arr[i]) {
      arr[0] = arr[i];
    }
  }
  //printing output
  printf("Largest element = %.2lf", arr[0]);

  return 0;
}

#include <stdio.h>

int main()

{

//declaring variables.

int no;

double arr[100];

//Taking input size of array

printf("Enter the number of elements between 1 to 100): ");

scanf("%d", &no);

//any numner input

for (int i = 0; i < no; ++i) {

printf("Enter element %d: ", i + 1);

scanf("%lf", &arr[i]);

}

// storing the largest number to arr[0]

for (int i = 1; i < no; ++i) {

if (arr[0] < arr[i]) {

arr[0] = arr[i];

}

//printing output

printf("Largest element = %.2lf", arr[0]);

return 0;

}

Output:-

In the above program, we have first initialized the required variable

arr[100] = it will hold the elements in an array.
i = it will hold the integer value to control the array.

no= it will hold the size of the array.

Printing output of the program to the user

Input Size.

Input elements of the array.
