Structs: Pass struct array to function

Create best function that recieves a Student array and gives back the index of the student with maximum force!
Use the function in the main() function

Hint: The array type is Student[], or Student* (pointer, soon you will understand). when we pass an array, the size MUST be passed too!

Solution

#include 

enum House{
    Griffindor, 
    Huffelpuff, 
    Ravenclaw,
    Slytherin
    };

typedef struct Student {
    char name[100];//Max. 99 chars for a name!
    int age;
    float magic_attack;
    float magic_defense, cleverness;
    enum House house; //it is an enum, must be defined before first use!
}Student;

float force(Student stud){
return stud.magic_defense+stud.magic_attack;
}

int best_student(Student Stud[], size_t size){//can be int size as well
int max_index=0;
int max_value=force(Stud[0]);//force must be declared earier!
for(int i=1;imax_value){
	max_index=i;
	max_value=force(Stud[i]);}
}
return max_index;
}


int main() {
Student Foes[]={{"Draco Malfoy",12,50,50,60,Slytherin},{"Gregory Goyle",13,47,50,25,Slytherin},{"Vincent Crabb",12,51,60,35,Slytherin}};

Student Friends[]={{"Harry Potter",12,55,70,35,Griffindor},{"Ronald Weasley",12,57,40,55,Griffindor},{"Hermione Granger",13,51,60,75,Griffindor}};

int max_index=best_student(Foes,3);
printf("In foes:%s with %.0f\n",Foes[max_index].name,force(Foes[max_index]));


max_index=best_student(Friends,3);

printf("In Friends:%s with %.0f\n",Friends[max_index].name,force(Friends[max_index]));

return 0;
}

Explanation

much better code... Let us move on, implement some dueling
