How to find greatest element of array by passing array as arguments?

// Write a program to find greatest element of array by passing array as arguments..

int main()

{

    int a[10],n,greatest,i;

    int gr(int *p,int n);

    printf("\n enter N:");

    scanf("%d",&n);

    printf("\n enter array:");

    for(i=0;i<n;i++)

    {

        printf("\n value at a[%d]:",i);

        scanf("%d",&a[i]);

    }

    greatest=gr(a,n);

    printf("\n greatest element=%d",greatest);

}

int gr(int *p,int n)

{

    int i,max;

    max=*p;

    for(i=0;i<n;i++)

    {

        if(max< *(p+i))

            max= *(p+i);

    }

    return max;

}

Output:

enter N:5

 enter array:

 value at a[0]:41

 value at a[1]:78

 value at a[2]:52

 value at a[3]:63

 value at a[4]:98

 greatest element=98
