Unformatted text preview: 4) a) 1) There is no # in front of include <iostream>. 2) There are “” in place of “{}” in order to show the boundaries of main(). 3) When defining the variable total, double is misspelled as doub. 4) There is no “;” at the end of the line defining the variable int n. 5) In order to raise 3.1 to the power of “total”, you must write it as pow(3.1,total), not as 3.1^total. 6) In the cout line, the arrows are pointing the wrong direction. They should be << not >>. The new output of the program is “n is equal to 48”...
