Pls correct my String program

Question

Task: in place of an integer ranging (0-9) we should print "GG",rest as it is.
Ex:
I/P: 2 out of 5 are well
O/p: GG out of GG are well

string enter;
cin>>enter;

int j;
for(int i=0;i<enter.length();i++)
{j=enter[i];

if(j>=48&&j<=57)
{
cout<<"GG";
}
else
cout<<enter[i];
}j=0;
return 0;

Answer 1

by default cin reads one word at a time. to read whole line at once you can use getline() .

int main(){
string enter;

getline(cin,enter); // to read entire line

int j;
for(int i=0;i<(int)enter.length();i++)
{j=enter[i];

if(j>=48&&j<=57)
{
cout<<"GG";
}
else
cout<<enter[i];
}j=0;
return 0;
}

There are some other ways too..
