swap

Swapping elements in a one$-$dimensional array is a useful exercise to remind students about the much needed temp variable when swapping elements!

int temp $=\frac{,}{\frac{?}{?}}$ copy the value of the element you will replace

$//$replace the element you stored in temp with the new value within the array

array

array$|=$ temp; $//$use the temp var which holds the original value.

It's very common to forget about the temp variable when swapping which results in a duplicate value within the array while also losing one of the values permanently This

mehod does not require and should not use a loop structure. This is because you already know which two pairs of elements to swap. You are not applying it to every element! Just two!
