i am not getting the results. why?

Question

#include <stdio.h>
#include <conio.h>
void main()
{
int a,b,sum;
printf ("Enter first number:");
scanf ("%d",&a);
printf ("Enter second number:");
scanf ("%d",&b);
sum=a+b;
printf ("summation=%d",sum);
getch();
}

Answer 1

well I guess you tried this on sololearn code playground or any modern IDE and If you did so , then there is no chance that it's gonna work.
First thing <conio.h> is no more supported and that means you can't use any of it's functions too so using void main and getch() is useless. Just edit it and little bit , remove that #include<conio.h> , replace void main() by int main() and getch(); by return 0; it'll work successfully .
