Question

The ________ function will change a character argument from lowercase to uppercase

Answer 1

The "toupper" function will change a character argument from lowercase to uppercase.

What is argument?

You can provide a function more information by using an argument. The data can then be used by the function as a variable as it executes. To put it another way, when you construct a function, you have the option of passing data as an argument, also known as a parameter.

Some characteristics of argument are-

• Variables only used in that particular function are called arguments.
• When we call the function, you must specify that value of an argument.
• Function arguments provide your applications access to more data.

Argument can be used in the following form:

1. Add a string argument support to the method prototype and implementation: howMuchFun=string(string amount
2. Modify your return type to read "fun" plus the return amount;
3. Insert the string howMuchFun between the parenthesis when you execute the function ("tons of")
4. Their capabilities can be greatly increased by adding arguments! Adding comma between each argument will allow you to add more (string amount, string noun).
