what is the best way to find shortcuts in c++?

Question

best ways to find c++ code tricks or shortcuts which can make program shorter.

Answer 1

1.STL :
If shorter means reducing the length of the code you have to write, c++ offers STL for commonly used algorithms like search, sort, finding maximum minimum, set operations etc.
For instance :
Instead of writing youe own sorting function. To sort an array of size 'n' simply we can use
sort(array, array +n) ;

STL also offers common data structures so you don't have to implement them from scratch

For instance : if you want a stack of int, you can simply include stack header and make stack instead of writing your own stack as
:
stack <int > st;

The advantages of STL is it is efficient and less error prone as it is regularly maintained by active cpp community.

2.Loops :
I find range based loop more elegant and appropriate whenever I can use them
. Suppose we have to output an integer array of size n;

for(int i = 0; i < n; i++)
cout << array[i] ;

This can be written in much elegant way :
for(int element :array)
cout << element;

3.typedef :
Suppose I have to declare a unsigned long long variable I can do sth like this.

unsigned long long a, b;

Instead of writing unsigned long long in every place in my code. I can use
typedef unsigned long long ull;
and declare variables as:
ull a, b;

StackOverflow.com Is my webpage of choice to satisfy my code needs.

Answer 3

Note that shorter does not always mean better.

Answer 5

i mean are there any ways to effectively make your code a bit shorter.
