The command "cout" does not output the result

Use this command

C:\Users\DELL>FreeFem+±mpi 05.15学习程序书.edp

to run the following program,

load “MPICG”
load “medit”
load “metis”
include “getARGV.idp”
include “MPIplot.idp”
include “MPIGMRESmacro.idp”

searchMethod = 0;
assert(version >= 3.11);
real[int] ttt(10);
int ittt=0;
macro settt {ttt[ittt++] = mpiWtime();}//
verbosity=getARGV("-vv",0);
int vdebug=getARGV("-d",1);
int ksplit=getARGV("-k",10);
int nloc = getARGV("-n",25);
string sff=getARGV("-p,","");
int gmres=getARGV("-gmres",3);
bool dplot=getARGV("-dp",0);
int nC = getARGV("-N" ,max(nloc/10,4));

if (mpirank==0 && verbosity){
cout << "ARGV: ";
for (int i = 0; i < ARGV.n; ++i)
cout << ARGV[i] << " ";
cout << endl;
}

if(mpirank==0 && verbosity)
cout << " vdebug: " << vdebug << ", kspilt "<< ksplit << ", nloc "<< nloc << ", sff "<<sff << “.” << endl;

but “cout” does not output the result. Why?

Because your verbosity variable is set to 0. Please try to read your code before posting these questions.
