Not understaning what went wrong. I'm new at c++

[rclark22]

I've been trying to find how to correct the errors in my code even though it says it in my solutions. I still need a little assistance to connect the dots.

My assignment wants me to: Write a program that (1) reads a weight in pounds (integer) and ounces(double) and outputs the equivalent weight in kilograms(integer) and grams(double) and (2)accepts input of kilograms and grams and outputs the equivalent in pounds and ounces. Use at least three functions: one for input, one or more for calculating, and one for output. Include a loop that lets the user repeat this computation for new input values until the user chooses to end the program. There are 2.2046 pounds in a kilogram, 1,000 grams in a kilogram and 16 ounces in a pound.
kilograms_per_pound = .454
pounds_per_kilogram = 2.2046

  Purpose: Convert between meters/centimeters and feet/inched at user's option.

I've been trying to find how to correct the errors in my code even though it says it in my solutions.

What errors? We're not mind-readers. If you have a problem, tell us what it is.

[plexus]

Errors found at first sight:

1. char ; in main() (Line 32)
2. #include <sstream> in between function signature and function body.
3. the function "definition" convert_M_to_E() is terminated by a ';', which makes it a prototype without a body. However, the presumed function body follows a few lines later with a few variable declarations in between.
4. Theres a stray return 0; } at the end of your code.

Other things that are weird / kinda wrong:
A: Theres two overloads of convert_M_to_E() which seem kinda redundant. Besides that one is not implemented and the other is "implemented" in a wrong way (see 3. above).
B: The functions E_TO_M() and M_to_E() don't do anything.
C: even if the definition of convert_M_to_E() would be correct, it's unusual or even wrong in C++ to declare variables in between the funtion signature and its body.
D: there are several function declarations inside of some of your functions, like the declaration of Metric_to_English() inside of main().

There are a few more things that look weird, but I think that's enough for now.
