 # C Program to Find Largest Element in an Array

#### In this example, you will learn to display the largest element entered by the user in an array.

To understand this example, you should have the knowledge of the following C programming topics:

## Find the Largest Element in an array

``````#include <stdio.h>
int main() {
int i, n;
float arr;
printf("Enter the number of elements (1 to 100): ");
scanf("%d", &n);

for (i = 0; i < n; ++i) {
printf("Enter number%d: ", i + 1);
scanf("%f", &arr[i]);
}

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

printf("Largest element = %.2f", arr);

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 `arr[]`.

To find the largest element,

• the first two elements of array are checked and the largest of these two elements are placed in `arr`
• the first and third elements are checked and largest of these two elements is placed in `arr`.
• this process continues until the first and last elements are checked
• the largest number will be stored in the `arr` position

We have used a `for` loop to accomplish this task.

``````for (i = 1; i < n; ++i) {
if (arr < arr[i])
arr = arr[i];
}
``````
