Ways to Iterate over characters of a string in C++ coding

Given a string str of size N, the duty is to traverse the string and print all of the characters of the given string.

Examples:

Input: str = “GeeksforGeeks”
Output: G e e ok s f o r G e e ok s

Input: str = “Coder”
Output: C o d e r

 

Naive Approach: The easiest ways to resolve this drawback is to iterate a loop  on vary [0, N – 1], the place N denotes the size of the string, using variable i and print the worth of str[i].

Below is the implementation of the above strategy:

G e e ok s f o r G e e ok s

Time Complexity: O(N)
Auxiliary Space: O(1)

Auto key phrase – based mostly Approach: The string might be traversed using auto iterator.

Below is the implementation of the above strategy:

G e e ok s f o r G e e ok s

Time Complexity: O(N)
Auxiliary Space: O(1)

Iterator – based mostly Approach: The string might be traversed using iterator.

Below is the implementation of the above strategy:

G e e ok s f o r G e e ok s

Time Complexity: O(N)
Auxiliary Space: O(1)
