Sorting Netpay by Pointers Question

LaC0saNostra (82)
Ok so I think I'm on the right track with finishing this program.

Errors:
1.) C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp In function `int main()':
2.)46 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp cannot convert `float*' to `int*' for argument `1' to `void pointer_array_sort(int*)'
3.) C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp In function `void pointer_array_sort(int*)':
4.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `n' undeclared (first use this function)
5.) (Each undeclared identifier is reported only once for each function it appears in.)
6.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `p' undeclared (first use this function)
7.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `item' undeclared (first use this function)

I know I need to modify my example bubble sort program I replaced at the bottom where my old sort function was but I don't exactly get it. Can you help me just a little bit more. I really wanna understand how to do this. I believe I need to use the value parameters instead of the item variables. Can anybody help me thus farther

Try and understand the error messages the compiler gives you. They can be a little cryptic at first, but generally give you a good idea what the problem is. Sometimes the line numbers can be off slightly, so it's a good idea to look back a line or two.

46 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp cannot convert `float*' to `int*' for argument `1' to `void pointer_array_sort(int*)'


Line 43:
 
 
pointer_array_sort(netpay);

You're try to pass to pass netpay to pointer_array_sort. netpay is delared as an array of floats. 
 
 
void pointer_array_sort(int*Values)

pointer_array_sort says it accepts an array of ints. You can't pass an array of floats to a function that accepts an array of floats. Hence, the diagnostic: cannot convert `float*' to `int*'


139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `n' undeclared (first use this function)

You're trying to use n in your for loops. n is not passed in.


139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `p' undeclared (first use this function)

You're trying to use an array called p which is not defined. Did you mean to use Values?


139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `item' undeclared (first use this function)

Again, you're trying to use a variable (item) that is not defined.

Errors:
1.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `n' undeclared (first use this function)
2.) (Each undeclared identifier is reported only once for each function it appears in.)
3.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `p' undeclared (first use this function)
4.)139 C:\Users\-6\Desktop\Dev-Cpp\ESC\Practice.cpp `netpaty' undeclared (first use this function)

How do I fix this for loop to implement it into my program for execution?
