int marks[10], i, high, low;

for(i = 0 ; i < 10 ; i++)
{
printf("\nMarks %d :", i + 1);
scanf("%d", &marks[i]);
}

high = low = marks[0];

for(i = 0 ; i < 10 ; i++)
{
if(marks[i] > high) high = marks[i];
if(marks[i] < low) low = marks[i];
}

printf("\nHighest marks is %d\nLowest marks is %d", high, low);

return 0;
