The procedure is as follows: See the attached figure for the results:

# contains "stdio.h"

const？ int？ n = 10；

Invalid? Master ()

{

Floating? Student [n];

int？ I，add = 0；

floatmax，min，average

for(I = 0； I & ltn；; i++)

{

Printf ("Please enter the math scores of %d students (* *10 students):", I+1);

Scanf("%f ",& student [me]);

}

max = min = student[0]；

for(I = 0； I & ltn；; i++)

{?

if(student[i]>max)max = student[I]；

If (student [me] <; min)min = student[I]；

Add+= student [I];

}

Average value = add/(float) n;

Printf ("The highest and lowest average scores of these students are:% 2.0f \ t% 2.0f \ t% 2. 1f", max, min, average);

}
