[std::boolalpha](<http://en.cppreference.com/w/cpp/io/manip/booalpha>) and [std::noboolalpha](<http://en.cppreference.com/w/cpp/io/manip/booalpha>) - switch between textual and numeric representation of booleans.

std::cout << std::boolalpha << 1;
// Output: true

std::cout << std::noboolalpha << false;
// Output: 0

bool boolValue;
std::cin >> std::boolalpha >> boolValue;
std::cout << "Value \\"" << std::boolalpha << boolValue
          << "\\" was parsed as " << std::noboolalpha << boolValue;
// Input: true
// Output: Value "true" was parsed as 0

[std::showbase](<http://en.cppreference.com/w/cpp/io/manip/showbase>) and [std::noshowbase](<http://en.cppreference.com/w/cpp/io/manip/showbase>) - control whether prefix indicating numeric base is used.

[std::dec](<http://en.cppreference.com/w/cpp/io/manip/hex>) (decimal), [std::hex](<http://en.cppreference.com/w/cpp/io/manip/hex>) (hexadecimal) and [std::oct](<http://en.cppreference.com/w/cpp/io/manip/hex>) (octal) - are used for changing base for integers.

#include <sstream>

std::cout << std::dec << 29 << ' - '
          << std::hex << 29 << ' - '
          << std::showbase << std::oct << 29 << ' - '
          << std::noshowbase << 29  '\\n';
int number;
std::istringstream("3B") >> std::hex >> number;
std::cout << std::dec << 10;
// Output: 22 - 1D - 35 - 035
// 59

Default values are [std::ios_base::noshowbase](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>) and [std::ios_base::dec](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>).

[std::uppercase](<http://en.cppreference.com/w/cpp/io/manip/uppercase>) and [std::nouppercase](<http://en.cppreference.com/w/cpp/io/manip/uppercase>) - control whether uppercase characters are used in floating-point and hexadecimal integer output. Have no effect on input streams.

std::cout << std::hex << std::showbase
              << "0x2a with nouppercase: " << std::nouppercase << 0x2a << '\\n'
              << "1e-10 with uppercase: " << std::uppercase << 1e-10 << '\\n'
}
// Output: 0x2a with nouppercase: 0x2a
// 1e-10 with uppercase: 1E-10

Default is std::nouppercase.

[std::setw(n)](<http://en.cppreference.com/w/cpp/io/manip/setw>) - changes the width of the next input/output field to exactly n.

The width property n is resetting to 0 when some functions are called (full list is here).

std::cout << "no setw:" << 51 << '\\n'
          << "setw(7): " << std::setw(7) << 51 << '\\n'
          << "setw(7), more output: " << 13
          << std::setw(7) << std::setfill('*') << 67 << ' ' << 94 << '\\n';

char* input = "Hello, world!";
char arr[10];
std::cin >> std::setw(6) >> arr;
std::cout << "Input from \\"Hello, world!\\" with setw(6) gave \\"" << arr << "\\"\\n";

// Output: 51
// setw(7):      51
// setw(7), more output: 13*****67 94

// Input: Hello, world!
// Output: Input from "Hello, world!" with setw(6) gave "Hello"

Default is std::setw(0).

[std::left](<http://en.cppreference.com/w/cpp/io/manip/left>), [std::right](<http://en.cppreference.com/w/cpp/io/manip/left>) and [std::internal](<http://en.cppreference.com/w/cpp/io/manip/left>) - modify the default position of the fill characters by setting [std::ios_base::adjustfield](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>) to [std::ios_base::left](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>), [std::ios_base::right](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>) and [std::ios_base::internal](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>) correspondingly. std::left and std::right apply to any output, std::internal - for integer, floating-point and monetary output. Have no effect on input streams.

std::fixed sets the [std::ios_base::floatfield](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>) to [std::ios_base::fixed](<http://en.cppreference.com/w/cpp/io/ios_base/fmtflags>),
