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]);

how to get the largest number in a c++ array

#include <iostream>
using namespace std;
int main(){
   //n is the number of elements in the array
   int n, largest;
   int num[50];
   cout<<"Enter number of elements you want to enter: ";
   cin>>n;
   
   /* Loop runs from o to n, in such a way that first
    * element entered by user is stored in num[0], second 
    * in num[1] and so on. 
    */
   for(int i = 0; i < n; i++) {
      cout<<"Enter Element "<<(i+1)<< ": ";
      cin>>num[i];
   }
   // Storing first array element in "largest" variable
   largest = num[0];
   for(int i = 1;i < n; i++) {
      /* We are comparing largest variable with every element
       * of array. If there is an element which is greater than
       * largest variable value then we are copying that variable
       * to largest, this way we have the largest element copied
       * to the variable named "largest" at the end of the loop 
       *
       */
      if(largest < num[i])
         largest = num[i];
   } 
   cout<<"Largest element in array is: "<<largest;
   return 0;
}
