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.
Find the Largest Element in an array
#include <stdio.h>
int main(){
int i, n;
float arr[100];
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[0]
for (i = 1; i < n; ++i) {
if (arr[0] < arr[i])
arr[0] = arr[i];
}
printf("Largest element = %.2f", 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 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[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
We have used a for
loop to accomplish this task.
for (i = 1; i < n; ++i) {
if (arr[0] < arr[i])
arr[0] = arr[i];
}
