To understand this example, you should have the knowledge of the following C programming topics:
#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,
arr[0]
arr[0]
.
arr[0]
positionWe have used a for
loop to accomplish this task.
for (i = 1; i < n; ++i) {
if (arr[0] < arr[i])
arr[0] = arr[i];
}
