IO-04. Mixed type data format input (5) time limit MS Memory limit 65536 KB code length limit 8000 B procedure StandardAuthor Joleen (Tsinghua University)

The subject requires a program, sequentially read into the floating-point number 1, Integer, character, floating point number 2, and then by character, Integer, floating-point number 1, floating point number 2 order output.

Input format:

Enter the floating-point number 1, Integer, character, floating-point number 2 in the order given in a row, separated by 1 spaces.

Output format:

Output in a row in the order of characters, integers, floating-point number 1, floating-point number 2, where the floating-point number retains 2 digits after the decimal point.

Input Sample:

2.12 C 4.7

Sample output:

C 88 2.12 4.70

Operation Result:

a.cpp:in function ' int main () ': a.cpp:11:4: error:expected '; ' Before ' cout '
Solution: A semicolon is added to each line after the cout.

Run Result: Compile error

a.cpp:in function ' int main () ': A.cpp:11:29:error:cannot convert ' std::ios_base& (*) (std::ios_base&) ' to ' std:: Ios_base::fmtflags {aka Std::_ios_fmtflags} ' for argument ' 1 ' to ' Std::_setiosflags std::setiosflags (std::ios_base:: fmtflags) ' A.cpp:12:29:error:cannot convert ' std::ios_base& (*) (std::ios_base&) ' to ' std::ios_base::fmtflags {aka Std::_ios_fmtflags} ' for argument ' 1 ' to ' std::_setiosflags std::setiosflags (std::ios_base::fmtflags) '

Solution: Leak the ios!!!! Ios::fixed
