The conversion specifier ______ is used in a scanf format control string to indicate that an integer will be input and in a printf format control string to indicate that an integer will be output

%d

State that a program will calculate the product of three integers

a) /* Calculate the product of three integers */

Define the variables x, y, z and result to be of type int.

b) int x, y, z, result;

Prompt the user to enter three integers

c) printf( "Enter three integers: " );
