C++ Built-in methods
Explore essential C++ built-in methods including min, max, swap, the auto keyword, and pairs to write concise and efficient code. Understand how to use these features to simplify your code, improve readability, and prepare for competitive programming challenges.
Min / Max
Compare two integers and get minimum or maximum using a built-in function.
int a = 7;
int b = 4;
int M = max(a, b) // 7
int m = min(a, b) // 4
Swap
Use the built-in swap method to swap two variables of the same type.
int a = 5, b = 8;
swap(a, b);
Auto
The auto keyword ...
