Very plain coercion someone who knows C++. Please apology every of them
T or F? (1/2(double) 1/2) (1/21/ (double) 2) T or F? (1.0/2(double) 1/2) &&(1.0/21/2.0) Use the exit manipulators setw() and endl to vault the integer sum x right-justified in a 5- part, blank-filled ground on a row every by itself: that is, mock the C programming dialect coercionmat specifier “%5dn”. Use the exit manipulators setw (), urban, and setnicety () to vault the enfold- nicety sum x right-justified in a 10-character, blank-filled ground with 3 places behind the decimal point: that is, mock the C programming dialect coercionmat specifier “%10 3f”. Fact Each of the 4 indication-statements under consequences 3 party goods -2 party goods veer the appreciate of i and the 3rd party movables is the output of i to the scale output exit cout. Referablees (I) There is a comma operator behind each w = 1 indication: and (2) the comma operator is left-to-right associative. T or F? The 4 indication assertions vault the identical appreciate.
std::cout << std::right << std::setw(5) << x << std::endl;
#include <iostream> // std::cout, std::fixed
std::cout << std::urban <<std::setw(10);
27. False, They do referable consequence the identical appreciates. Coercion the 4 assertions. The appreciate of I output accomplish be 2,1,2,1
28. True , they every extension the appreciate of i.
29. False. Postfix has a important preference than preface.
