$11\mathrm{.}11$ LAB: All permutations of names

Write a program that lists all ways people can line up for a photo $($all permutations of a list of strings$).$ The program will read a list of one word names $($until $-1),$ and use a recursive method to create and output all possible orderings of those names separated by a comma, one ordering per line.

When the input is:

Julia Lucas Mia $-1$

then the output is $($must match the below ordering$)$:

Julia, Lucas, Mia

Julia, Mia, Lucas

Lucas, Julia, Mia

Lucas, Mia, Julia

Mia, Julia, Lucas

Mia, Lucas, Julia

My Code:

#include

#include

#include

using namespace std;

void PrintAllPermutations$($vector& names, vector& prefix, vector& results$)\{$

if $($names$.$empty$())\{$

string result;

for $($const auto& name : prefix$)\{$

result $+=$ name $+","$;

$\}$

result.pop$\_$back$()$; $//$ Remove the last comma

result.pop$\_$back$()$; $//$ Remove the space

results.push$\_$back$($result$)$;

$\}$ else $\{$

for $($size$\_$t i $=0$; i $<$ names.size$()$; $++$i$)\{$

vector remaining$\_$names $=$ names;

vector new$\_$prefix $=$ prefix;

new$\_$prefix.push$\_$back$($remaining$\_$names$[$i$])$;

remaining$\_$names.erase$($remaining$\_$names.begin$()+$ i$)$;

PrintAllPermutations$($remaining$\_$names, new$\_$prefix, results$)$;

$\}$

$\}$

$\}$

int main$()\{$

vector names;

string name;

while $($cin $>>$ name && name $!="-1")\{$

names.push$\_$back$($name$)$;

$\}$

vector prefix;

vector results;

PrintAllPermutations$($names$,$ prefix, results$)$;

for $($const auto& perm : results$)\{$

cout $<<$ perm $<<$ endl;

$\}$

return $0$;

$\}$

Error that won't go away:

main.cpp: In function $$bool testPassed$($std::ofstream&$)$:

main.cpp:$50$:$43$: error: too few arguments to function $$void PrintAllPermutations$($std::vector $>$&$,$ std::vector $>$&$,$ std::vector $>$&$)$

$50|$ PrintAllPermutations$($permList$,$ nameList$)$;

$|^$

main.cpp:$8$:$6$: note: declared here

$8|$ void PrintAllPermutations$($vector& names, vector& prefix, vector& results$)\{$

$|^$~~~~~~~~~~~~~~~~~~~

Please fix.
