A C program to add two very large numbers whose datatype is not specified?

Question

The numbers can be positive,negative or floating point but the result should display their sum.

Answer 1

#include<stdio.h>

#define data long int

int main()

{

data n1,n2;

scanf("%d%d",&n1,&n2);

print("%d",(n1+n2));

return 0;

}

Comments

Ridiculous.
What is the point of #define here? Just write the type.
When you use %d, that refers to int. This means you're inputting and outputting int types.
Also long int and int are the same thing.

Answer 2

#include<stdio.h>

#define data long int

int main()

{

data n1,n2;

scanf("%d%d",&n1,&n2);

print("%d",(n1+n2));

}
