Solution:

Well, in Java, there are a couple of ways to iterate through characters in a string. As per your question, you can use the .charAt() or the .toCharArray() function. These two are the easiest and efficient ways to iterate through chars in a string. Let me give an example by using them in my program.

 Using .charAt() function:

public class MyClass{	
	public static void main (String[] args){
		String str = "I am Gavin";
		for (int n = 0; n < str.length(); n++){
			System.out.print(str.charAt(n));
		}
	}
}

Using .toCharArray() function:

public class MyClass{
	public static void main (String[] args){
		String str = "I am Gavin";
		char[] chars = str.toCharArray();
		for (char ch : chars){
			System.out.print(ch);
		}
	}
}

Above both program will produce the same output

I am Gavin

Problem: I want to iterate through each element in the map<string, int> without knowing any of its string-int values or keys. What I have so far: void output(map<string, int> table) { map<string, int>::iterator it; for (it = table.begin(); it != table.end(); it++) { //How do I access each element? } }

Problem: I am attempting to iterate over the following string, using a for loop: >>> for a,b,c in "cat" print(a,b,c) Now what I intended for this to do was print out each character in the string individually on one physical line, instead I receive an error. I am aware that this is ... list operator []: >>> for a,b,c in ["cat"] print(a,b,c) c a t But could someone explain why this is the case?
