Question

I’m a beginner at C, and using Turbo C++ compiler (16 bit).

In the software I’m writing, the maximum answer is around 32000. If I want a number larger than that, I use long int.

If I execute the following program:

#include <stdio.h>
void main()
{
    long int x;
    x=40000;
    printf("%d", x);
}

Then I get an error that the constant value is long in function main().

How can I get an answer more that 32000 and get rid of this error?
also nw i change %d to %ld and use 40000L bt when i use unsigned integer then also i need to use ‘l’ with 40000//??

Answer 1

Use %ld in printf for the long int. %d is for int which only has 16 bits in your compiler. And for the error message, use x=40000L.
