Thread: C Program help

this is what i need my program to do. I am having problems at multiple stages so i will put what i have even tho it might be fragmented. please help!

2. it should prompt the user for the input file name of the file containing the data to sort.
3. If the program can't open the file or if no file name is entered (^d or ^z is entered for EOF), it should print an error message and exit.
4. The file will contain numbers that could be positive or negative integers or floating point numbers two numbers to a line.
5. The program should only handle the first 90 numbers in the file.
6. The program should read the numbers from the file into an array and then sort in ascending order (low to high) them.
7. If the program encounters a non-numeric value in the file, it should print an error message indicating the line number of the line containing the error and discard that input line in the file and go to the next line.
8. The program should print the sorted list of numbers, four numbers to a line in columns fifteen characters wide with four digits to the right of the decimal point.
9. After printing the sorted list, it should print:
o There were <number> numbers found in file <file name>.
o The largest number found was: <number>
o The smallest number found was: <number>
o The average of the values is: <number>
10. If there are no numbers in the file, the program should only print the following line
o There were 0 numbers found in file <file name>.
11. Include comments in your code (see project two for the required comment block formats) to explain what the code does.
12. See the examples below for spacing and formatting.
13. Your program should be well structured. The work should be done in functions, not in main. Include at least four functions that you will define.
14. The program can not use global variables except for a debug variable.

Code:

#include <stdio.h>
void greeting(void);
void sortArray (float *nums[], int *last);
int main()
{
float nums;
int last;
greeting();
sortArray(&float nums[90], &int last);
return 0;
}

void greeting ()
{
printf("Hello World! My name is Daniel Greene");
return;
}

void sortArray(float *nums[], int *last)
{
    int smallest;
    int temp;

    for (int current = 0; current < last; current++)
    {
        smallest = current;

        for (int walk = current + 1; walk <= last; walk++){
            if (nums[walk] < nums[smallest]){
                 smallest = walk;
                 temp = (float)nums[current];
                 nums[current] = nums[smallest];
                 nums[smallest] = (float)temp;
            }
}

return;
    }

then I have some code here too that i dont know whats going on.

Code:

#include <stdio.h>

// Function Declarations
void greeting();
int openFile(FILE* FP);
MAX_SIZE [90];

int main (void)
/* Local Declarations */

{
float nums[90];
FILE*FP;

greeting();
openFile(&FP);
/*Statements*/


return 0;
} /* end of Main */


/* Function Name: greeting

 * Input Parameters: none

 * Description: Function prints out class, project and name.

 * Return Value: returns nothing.
*/
void greeting ()
{
printf("\n\nCOP 2220-50184 Project 3: Daniel Greene\n\n") ;
return;
}


int openFile(FILE** FP)
{
int fName

printf("\n\nEnter File Name\n\n") ;
scanf("%s, fName");
fopen(fName, "r");
if(!fName)
    {
     printf("File name not valid.\n");
    }




return FP;
}

How much are you willing to pay?

What am I going to do with 40 ellipses? Pause in thought a lot I guess. Why did you post your "do it for me" question on the C++ board when you want C?

My original post was going to be about how you aren't getting your program done because you don't know how to read. Your latest post proves that point.

Hmm... this sort function seems strangly similar to this.
