#includeiostream
#includestdexcept
usingnamespacestd;
intf(intval)
{
intresult=1;
for(inti=1;i=val;i)
{
result*=i;
}
returnresult;
}
intmain()
{
charc;
try
{
intval=1;
cinval;
coutf(val);
}
catch(overflow_errorerr)
{
do{
couterr.what()\"再试一次？按下Y或者N\";
if(cin
}
}while(cinc);
}
cin.get();
cin.get();
return0;
}
怎么才能让程序里的do..while语句正常运行比如我输入的是val=10000000

try

catch(overflow_errorerr)
{
do{
couterr.what()\"再试一次？按下Y或者N\";
if(cin
}
}while(cinc);
}
system(\"pause\");
return0;
}
这么改看看可以不？
