Ok, you basically have it right, but you are not yet multiplying the argument value. So your function should be<\/p>\n

double functionXYZ (double data)\n{\n    return data * 10;\n}\n<\/code><\/pre>\n
The type before the function name<\/em> determines its ‘return type’ (what type of variables can be expected to be returned by this function). In this case, it is double<\/code>, so as long as you use the return<\/code> keyword with a double value, you are correctly returning a double.<\/p>\n
Edit<\/strong><\/p>\n
There are also a number of bugs in your main()<\/code> function. To get this to compile correctly, you must do the following:<\/p>\n
Make sure variables have unique names; You have double val<\/code> several times. That means you are trying to declare to the compiler that there is a double<\/code> variable called val<\/code> more than once, which is an error.<\/p>\n
Change the line(s) that look like this<\/p>\n
printf(\" Your total is: %if \\ n \" result1);\n<\/code><\/pre>\n
to <\/p>\n
printf(\" Your total is: %if \\n \", result1);\n<\/code><\/pre>\n
Note adding the missing comma. Also removing the space between the \\ and the n is not a compile bug but it is an obvious typo.<\/p>\n
Make sure that every time you refer to a variable, it is one you have actually defined. So for example<\/p>\n
double result2 = functionXYZ (val2);\n<\/code><\/pre>\n
calls your function with a variable called val2<\/code>, except at no point in your code to you actually define<\/em> val2<\/code>.<\/p>\n<\/p><\/div>\n
