i have a cin.getline string that i want to place into an array , is it possible? if it isnt. is there another way i can do it?
here is a bit of the code. i need to put the input (string) into the array.
void newperson ()
{
int count, numppl;
cout<<"How many people do you want to introduce?"<<endl;
cin>>numppl;
for (count=0 ; count <=numppl ; count=count +1)
{
cin.getline (input, 200, '\n');
}
}
a string is an array.
you can get a specific value in the array using brackets (example: [])
if you want some number to become some array...
here is a very basic sample code segment I made:
Code:int numberarray[32]; int number; int numbercopy; int counter; cin>>number; numbercopy = number; // transfer value from int to array // note: the numbers are stored backwards for(counter=0;number>0 && counter<32;counter++) { numberarray[counter] = numbercopy % 10; numbercopy %= 10; } // search for the last value of the array int arraylength; for(counter=0;counter<32;counter++) { if (numberarray[counter]=='\0') // '\0' = NULL { arraylength=counter; break; } } // reverse order of array using "swap" method int temp; for(counter=0;counter<=arraylength/2;counter++) { temp=numberarray[arraylength - counter]; numberarray[arraylength - counter] = numberarray[counter]; numberarray[counter] = temp; } // print out the array for(counter=0;counter<arraylength;counter++) { cout<<numberarray[counter]; } cout<<endl; // convert the number array back to type integer; for(counter=0;counter<arraylength;counter++) { numbercopy = numbercopy * 10 + numberarray[counter]; }

think only with code.
write only with source.
Yes you can here is a sample programIf you don't have string.h then it gets a bit more complicated I think....
Code:#include <iostream.h> #include <string.h> int main() { string names[5]; names[0]="Arminas"; names[1]="Lostminds"; names[2]="says"; names[3]="yes"; for (int x=0;x<4;x++) cout << names[x] <<' '; cout << "\n\nWhat is your name?\n"; cin >> names[4]; cout << "\n\n\t" << names[4] << " that is a good name."; getchar(); }//end main

I dont know very much about C++ but I think if you write like so
then mystring is stored in an object of type string that does a lot of bookkeeping for you.Code:#include <iostream> using namespace std; int main() { string mystring; cout<<"enter a string"<<endl; cin>>mystring; return 0; }
and if you want an array of strings its:
to access the first letter of the first word it is:Code:string customer_names[MAX];
to access the first word it is just : customer_names[0];Code:cout << customer_names[0][0];
"The most common form of insanity is a combination of disordered passions and disordered intellect with gradations and variations almost infinite."
doing forget to #include <string> before declaring variables of type 'string'... if you don't you'll get errors.
