Too many arguements

[Ryoka117]

Every time I try to compile my code I keep getting an error stating that there are too many arguments in my function and I don't understand what that means or what to do.

#include <iostream>

using namespace std;

double average();

int findLowest();

void findLetter();



int main()
{
    int x, y, z;

    cout<<"please enter three grades"<<endl;

    cin>>x>>y>>z;

    average(x, y, z);
    return 0;

}

double average(int x, int y, int z)
{

    double a = (x+y+z) / 3;

    return a;
}

the problem is that your average prototype does not define three ints like your declaration

your code should be

#include <iostream>

using namespace std;

double average(int,int,int); // fixed:  error was here 

int findLowest();

void findLetter();



int main()
{
    int x, y, z;

    cout<<"please enter three grades"<<endl;

    cin>>x>>y>>z;

    average(x, y, z);
    return 0;

}

double average(int x, int y, int z)
{

    double a = (x+y+z) / 3;

    return a;
}

Line 6: Your function prototype for average() says it takes no parameters.

Line 22: You call average() with three parameters. Your call must agree with the function prototype.

Change your function prototype so that is agrees with line 27.
