find maximum number in 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;
}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;
