The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Exercise - Writing Strings in Solid

This video tutorial guides viewers through exercises involving string manipulation. It starts with creating a string called 'favorite color' and setting its value to 'blue'. The tutorial then covers creating functions to return the string literal, change the color to the user's favorite, and count the number of characters in the string. Finally, it discusses deploying the contract for these exercises.

What is the initial task involving the 'favorite color' string?

• Create a string and set its value to 'green'.

• Create a string and set its value to 'red'.

• Create a string and set its value to 'blue'.

• Create a string and set its value to 'yellow'.

What should the first function return?

• The string literal of 'favorite color'.

• The length of the string.

• The number of vowels in the string.

• The string in uppercase.

What is the purpose of the second function?

• To change the string to 'purple'.

• To change the string to 'yellow'.

• To change the string to the user's favorite color.

• To change the string to 'red'.

What does the final function calculate?

• The number of words in the string.

• The number of characters in the string.

• The number of sentences in the string.

• The number of spaces in the string.

What is the final step after creating the functions?

• Deploy the contract to test the functions.

• Delete the contract.

• Write a report on the functions.

• Share the code with a friend.
