how to out put the array number; i want to print the array contain largest number?

- maximum number of cars sold(settle)
- salesman that sales the most car(dunno how to do)
- sum of car sold(settle)

It looks like the code you provided is your attempt to cover some of the criteria, but there are certainly better ways to do this. I still tried to make an example as similar to your method as possible. If I could see the original question or your full code I might be able to assist you better, but here's what I got. (C++)

Since you are using the indices of your array as the employee id numbers, all you have to do to "print the i as the salesmen ID" is record the index number in the same manner you recorded the "max." i.e.

if (cars[i] > max)
{
max = cars[i];
salesmanID = i;
}

include <stdio.h>

int main()
{
int i, max, sid, sum, cars[10];

printf("Enter the 10 numbers : ");
for(i = 0; i < 10; i++) { scanf(" %d", &cars[i]); }

max = cars[0]; sid = 0;
sum = cars[0];

for(i = 1; i < 10; i++)
{
if(cars[i] > max) { max = cars[i]; sid = i; }
sum = sum + cars[i];
}

printf("Max no. of cars sold : %d, by salesman ID : %d\n", max, sid);

printf("Total sales of car : %d\n", sum);

return 0;
}
