How do I write a for loop to enter a series of intergars and display smallest and largest one?

Answer 1

In what language?

get first input and save it in intLow and intHigh

for i = 1 to 10
get input into variable intInput
if intInput < intLow save intInput into intLow
if intInput > intHigh and intHigh
end for

print intLow and intHigh

Answer 2

You didn't say how the integers are being entered and what language you are using.
Let's assume we have a fixed array of integers $integers and we have defined if necessary $smallest and $largest

for (a=0, a<= $numOfIntegers, a++)
{
if (a == 0)
{
$smallest = $integers[a];
$largest = $integers[a];
}
if ($smallest > $integers[a])
{
$smallest = $integers[a];
}
if ($largest < integers[a])
{
$largest = $integers[a]
}
}

You can adapt this to your language and then display $largesst and $smallest. If you need to enter the integers in reeal time, you will need to replace the array with input and use a while loop or something similar. Best I can do with the information you gave

Answer 3

Which programming language do you want to write the code in?

Answer 4

what language?

in c/c++ it could look something like:

int counter = 1;
int highest = 0;
int lowest = 0,
int entry;

for (counter; counter<=10; counter++){
/*get entry*/
/*check if entry is lower than lowest or higher than highest and replace as necessary*/
}/*end of for loop*/

/*print results*/

Answer 5

Why use a for loop at all?


var myArr = [1,2,3,4,5,6,7,8];
alert("Lowest: " + myArr[0] + "\nHighest: " + myArr[myArr.length - 1]);
