Thread: Help with the below program

The below program is not functioning properly I don't know if I have called the function "Integer" by passing its address properly....Please help....


insert

Code:

#include<stdio.h>
#include<conio.h>


int integer()
{
  int a;
  scanf("Enter the second number %d",&a);
  return a;
}


int subtract(int c, int (*q)())
{
  int h;
  h = q; /*integer function called*/
  h = c - h;
  printf("%d",h);
  getch();
}


void main()
{
  int a;
  scanf("Enter first integer %d", &a);
  int (*p)();
  p = integer; /*to store the address of integer function*/ 
  subtract(a,p); /*Passed the address of function to subtract*/
  getch();
}

k thank you......but if i woul have used

insert

Code:

  
int *h;
h = q; /*to store the address of integer function*/

will this work without the braces ??

Code:

nt integer()
{
  int a;
  scanf("Enter the second number %d",&a);
 ...

your scanf is looking for "Enter the second number [0-9]*" , that does not seem like a reasonable expiation for user input.
