I have three integers
I would like to determine what is the highest and which is the lowest value using Objective-C
Thank you!

To compare 3 values, use the logical AND (&&) operator to chain multiple conditions. When using the logical AND (&&) operator, all conditions have to return a truthy value for the if block to run. Copied!
Comparing three integer variables is one of the simplest program you can write at ease. In this program, you can either take input from user using scanf() function or statically define in the program itself. We expect it to be a simple program for you as well.
We can also compare all the three numbers by using the ternary operator in a single statement. If we want to compare three numbers in a single statement, we must use the following statement. In the following program, we have used a single statement to find the largest of three numbers.
It is good to store that numbers in an array. Just plain C array is good enough and in Objective-C best for performance. To find a minimum you can use this function. Similar for maximum.
int find_min(int numbers[], int N){
int min = numbers[0];
for(int i=1;i<N;i++)
if(min>numbers[i])min=numbers[i];
return min;
}
If that is just three numbers you can do the comparisons manually for best performance. There is a MIN() and MAX() macro in Cocoa in Foundation/NSObjCRuntime.h. For the maximum, just do:
int m = MAX(myI1, MAX(myI2, myI3));
This may be scaled to more numbers and may be faster than the first approach using loop.
