max_element function in c++

Question

code 1:
//
#include<iostream>
#include<algorithm>

int main(){
int arr[7]{1,2,3,6,4,5,3};
int *m = std::max_element(arr, arr + 7);
std::cout << *m;
return 0;
}

//

code 2:
//
#include<iostream>
#include<algorithm>

void rr(int arr){
int *m = std::max_element(arr, arr + 7);
std::cout << *m;
;
}

int main(){
int arr[7]{1,2,3,6,4,5,3};
rr(arr)
return 0;
}
//

when i am compiling code 1 , it is ok. But when i am compiling 2nd one its saying error.Can anyone tell me what is the problem and how to solve it ? I want to take the max value from function

Answer 1

In the second code, you are trying to pass the array as a single integer, not as a pointer to integers. The parameter type should be int*.
There is also a semicolon missing after the function call to "rr()" in main.

Answer 2
