    Putchar() to print an integer value?

    Ok, I swear my book is wrong here.

    int main ( void )
       int amount = 65;
       printf("Value of amount %d", amount);
    	putchar( 65 ); /*putchar prints the character value of an entered integer*/
       return 0;
    The above is correct, as function putchar() takes integer 65 and prints A as its character equivelent. But then the book asks me to re-write the above as an exercise so putchar prints the value stored in integer variable amount. I was always told putchar cannot output integers, it can olnly read them in and then translate them to the character value. Is my book wrong here?

    hmm... perhaps the idea is to get you to convert 65 to '6' and '5' and putchar() those?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
