I keep getting an error for the last line. error: expected declaration or statement at end of input

#include

int main(void) { double average(int x, int y);

int main(void){ int x, y;

double result;

printf("Enter first integer:"); scanf("%d", &x); printf("Enter second integer:"); scanf("%d", &y);

result=average(x,y);

printf("Average=%f",result);

return 0;

double average(int x, int y){ return (x + y)/2.0;} }
