This simple C program shows simple arithmetic calculations.

``` #include <stdio.h> // main() function… int main( ) {     // variables declaration     int  x, y, z;     // variables initialization, assign 20 to variable x…     // or put the value of 20 in memory location labeled by x     x = 20;     y = 2;     printf("Given x = 20, y = 2\n");     printf("\nx / y = %d", x / y);     // do some basic calculations     x = x * y;     y = y + y;     printf("\nx = x * y");     printf("\ny = y + y");     printf("\nNew value for x / y = %d", x / y);     z = 20 * y / x;     printf("\nz = 20 * (y / x) = %d\n", z);    return 0; } ```

To my horror at first sight the assosciated characters d i o u x c s e,f,g % are used with the assumption that to discuss them and how to use them is so basic that they are not discussed. In embedded applications e.g. pic uCs I program quite well in integer arithmetic. This of course has a big problem when you want decimals. Eg. 355/113 is a good approximation to PI. There are work arounds to preserve the decimals, but C as used in uC would seem to be a better way. Which brings me back to the C language and scanf, printf.... where do I find an article which step by step shows the usage of the formaters , hopefully with examples? Bye and thanks Fred Madrid``` View Tutorial          By: Fred Mah at 2012-09-22 07:40:27 2 View Comment`Hi Fred, I found this link which has more explanation on it. http://www.cdf.toronto.edu/~ajr/209/notes/printf.html` View Tutorial          By: Boulvat at 2012-09-25 08:36:48
