need help returning float values from subprograms

it seems i can only return an integer value from a subprogram? i need a float value returned is there something i'm missing here? i wrote this quick block of code to show you what i mean. say i type in 6.67 in the get_z function it then returns to the main function and assigns it to z. when i print z in the main function it prints as 6.0000 etc

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
  float z;
 
      z=get_z();
      printf("z in main fuction = %f\n", z);
     
      system("PAUSE");
      return 0;
}


int get_z()
{
  float z;
     
      printf("please enter # for z: ");
      scanf("%f", &z);
     
      return z;
}

define get_z() to return a float

Code:

---

float get_z();

now it just returns a value of 1.000 no matter what number i enter... any idea why?

Post your code.
Kurt

its the same thing but just with the float get_z as opposed to the int get_z... i'm really confused as to why its not working

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
  float z;
 
      z=get_z();
      printf("z in main fuction = %f\n", z);
     
      system("PAUSE");
      return 0;
}


float get_z()
{
  float z;
     
      printf("please enter # for z: ");
      scanf("%f", &z);
     
      return z;
}

what compiler are you using? you need to turn up your warning levels.

Code:

---

#include <stdio.h>
#include <stdlib.h>

float get_z();

int main()
{
  float z;
 
      z=get_z();
      printf("z in main fuction = %f\n", z);
     
      system("sleep 2");
      return 0;
}


float get_z()
{
  float z;
     
      printf("please enter # for z: ");
      scanf("%f", &z);
     
      return z;
}

Put

Code:

---

float get_z();

---

before main.
As your code is right now it should not even compile. ( redifinition of function with different returntype )
