Calculating the Maximum of Three Values

The max() macro or template takes two values and returns the highest. What if you need to calculate the maximum of three values? You don't need to write a special function template for this purpose. Instead, apply max() to two arbitrary values of the three, and then apply max() once again to the result and the third value:

 
int l=10, m=11, n=7;
int highest = max(l,max(n,m)); //highest = 11
