segmentation fault with sprintf

[bajajv]

Hi, I am trying to convert integer to string.

this is my code -

long num = 23456789;
char buff[20];
sprintf(buff, "%s", num);
printf("%s\n", buff);

but I am getting segmentation fault in sprintf() call.

Any idea why this is coming?

That is because you have used %s which is the code for a string and then passed an integer.

By the way, when you replace "%s" with the format code for an integer, don't forget to include a qualifier indicating that it is a long integer.
