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

Arrays
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];
}
}
