3. Write a program to demonstrate your mastery of the printf() function. The program has several variables as follows: Integer: i, j, k Double: x, y, z Character: chl, ch.2 The program is supposed to perform the following k=2*i + 3*) print a statement that has the following output-the values showed by XX are to be determined at run time -you cannot hard-code them "i = XX, j = XX, and k = XX" x- 40.5 y = 50.6 z- 2.0*x+ 3.0*y print a statement that has the following output run time -you cannot hard-code them "X-XX, y-XX, and z = XX" the values showed by XX are to be determined at ch1 = 'w' assign value of ch1 to ch2 print a statement that has the following output run time -you cannot hard-code them "ch1-XX and ch2 = XX" the values showed by XX are to be determined at
