Structs: Pass struct to function

Create force function that recieves a student and gives back the sum of the magic_attack and magic_defense.
Use the function in the main() function

Hint: The Student is a types use it accordingly.

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 main() {
Student Foes[3]={{"Draco Malfoy",12,50,50,60,Slytherin},{"Gregory Goyle",13,47,50,25,Slytherin},{"Vincent Crabb",12,51,60,35,Slytherin}};

Student Friends[3]={{"Harry Potter",12,55,70,35,Griffindor},{"Ronald Weasley",12,57,40,55,Griffindor},{"Hermione Granger",13,51,60,75,Griffindor}};

int max_index=0;
int max_value=force(Foes[0]);

for(int i=1;i<3;i++){
    if(force(Foes[i])>max_value){
	max_index=i;
	max_value=force(Foes[i]);}
}
printf("In foes:%s with %.0f\n",Foes[max_index].name,force(Foes[max_index]));

max_index=0;
max_value=force(Friends[0]);

for(int i=1;i<3;i++){
    if(force(Friends[i])>max_value){
	max_index=i;
	max_value=force(Friends[i]);}
}
printf("In Friends:%s with %.0f\n",Friends[max_index].name,force(Friends[max_index]));

return 0;
}

Explanation

Student type object easily passed to a function, where we can use as usual.

That looks better, but could we pass a struct array to a function? It would be nice to write a maximum search only once!
