Summarize the steps needed to solve this problem.
Input: Given a string of 10 characters, print the character at index 3.
Given a string of 10 characters, print the character at index 3. 

The steps for solving this problem are: 
1. Initialize two variables, index and character, and set index to 0 and character to the first character in the string. 
2. While index < length of string, assign index + 1 to index and set character to the char at index. 
3. Print character. 
4. Set index to index + 1 and set character to the char at index. 
5. End while. 
6. Print character.
The steps to solve this problem are:
1. Initialize a variable to store the character at index 3.
2. Use a for loop to iterate through all characters in the string.
3. For each character, check if it is equal to the initialized variable.
4. If it is, print the character.
5. Repeat steps 2 and 3 until the end of the string.
6. The character at index 3 will be outputted.
