pointers to function error

hello guys i'm kinda new in here and in c also i've been practising pointers to functions and i've come up with this code :

 #include <stdio.h>
#include <stdlib.h>
typedef int (*fptr)(int,int);
void swapp(int*,int*);
int sub(int ,int );
int add(int ,int );
int operation(fptr,int,int);
int main()
    int n=10,n1=25;

    return 0;
void swapp(int *a,int *b){
    int temp=*a;
int add(int a,int b){
    return a+b;
int sub(int a,int b){
    return a-b;
int compute(fptr operation ,int a,int b){

    return operation(a,b);

when compiled i get "Segmentation Fault(core duped) can anyone help me debug this? and thx i just can't see anything wrong with the code


need prototype

int compute(fptr operation ,int a,int b);

There are many questions on pointers when it comes to structs here, but what I am doing here is a little bit more complicated and has left me stumped. I have a proc struct for xv6.
