## Example: Largest Element in an array

```
#include <stdio.h>
int main() {
int n;
double arr[100];
printf("Enter the number of elements (1 to 100): ");
scanf("%d", &n);
for (int i = 0; i < n; ++i) {
printf("Enter number%d: ", i + 1);
scanf("%lf", &arr[i]);
}
// storing the largest number to arr[0]
for (int i = 1; i < n; ++i) {
if (arr[0] < arr[i]) {
arr[0] = arr[i];
}
}
printf("Largest element = %.2lf", arr[0]);
return 0;
}
```

**Output**

Enter the number of elements (1 to 100): 5 Enter number1: 34.5 Enter number2: 2.4 Enter number3: -35.5 Enter number4: 38.7 Enter number5: 24.5 Largest element = 38.70

This program takes `n` number of elements from the user and stores it in the `arr`

array.

To find the largest element,

- the first two elements of array are checked and the largest of these two elements are placed in
`arr[0]`

- the first and third elements are checked and largest of these two elements is placed in
`arr[0]`

. - this process continues until the first and last elements are checked
- the largest number will be stored in the
`arr[0]`

position

```
// storing the largest number at arr[0]
for (int i = 1; i < n; ++i) {
if (arr[0] < arr[i]) {
arr[0] = arr[i];
}
}
```
