This is for c programming: I am having the following errors in my code. I have included the pseudo code provided by my professor as well as the main, calculations , and io. Please assist with my errors. Leave comments where you made any changes.

Thank you.

Errors:

stocks.c: 70:4: error expected expressin before 'float'

float * parseString(char str [])

stocks.c: 118:30: error: 'array' undeclared here(not in a function)

float mean = get_average(array, size)

stocks.c: 118:37: error: 'size' undeclared here(not in a functin)

float mean = get_average(array, size);

stocks.c: 125:5: error: conflicting types for 'print_results'

In file included from stocks.c: 17: 0:

io.h:18:6: note: previous declaration of 'print_results' was here

void print_results(const float array[], int size, float median, float min,

float max, float mean, float variance);

stocks.c:127:5: error: expected identifier or '(' before 'return'

return 0;

stocks.c:129:1: error: expected identfier or '(' before '}' token

This is my main:

* stocks.c

* program 4 is a program that will

*inputs data on the command line to process stock values

Here is my main:

*

* gcc -o stocks.x stocks.c

* ./stocks.x

/eed to use a single pointer to allocate the values into array, but how?

}

Here is the pseudo code:

Algorithms Data: Stock prices input on several lines, one long string or values separated by spaces Result: mean, variance, min, max, median, sorting of input data begin 2if the user enters nothing on the command line then give a description of the project; ask them to enter the stocks one one line separated by a comma & hit enter when done 5 end 6else if they enter one value then if it's a single number then Implement Project 3 logic in reading the data; end 10 end 11 else 12 13 14 15 end 16 else assume the delimiter is a ','; count the number of entries & allocate arrays; parse the input string and store the values into arrays
