Passing Computed Values on to the Outside World

Our example program:

   int i, j ;

   i = 5 ;
   j = 3 ;
   printf( "sum = %d, product = %d\n", i + j, i * j ) ;

included a printf() function call which illustrates how we incorporate values of expressions or variables into the output that printf generates. The string that we printed back in Part 1-3 is really called the format string. This string defines how the output is to be formatted. Most of the string in this example is composed of characters that are to be literally written to the output. The %d entries are called format specifiers and define how the values of expressions or variables are to be displayed. The only one we're using here is %d which indicates that the value is to be displayed as a decimal integer. The values to be output are found by evaluating the expressions following the format string. In this case the expression i + j is evaluated and it's value is printed at the point in the output where the first %d is positioned.

What is the line of output (not including the newline character) that this program will generate? (Remember that characters in the format string not associated with the % sign are output literally.
