some really weird problems with string !
I tried so hard to get all the functions working ... and now just when I'm putting the whole program together, the first function is giving me craps ! =(
Really weird, but this function which accepts string into an array (got help from someone here earlier) works perfectly on its own but when put in some sort of a control loop or a switch , it goes crazy... this is what I mean:
Code:
#include <iostream.h>
#include<string.h>
void enter();
const int MAX = 3;
char array[MAX][81]; //declared globally for other functions later.
int i;
int main(void)
{
enter ();
return 0;
}
----------------------------------string into array function----------------
void enter()
{
for (i = 0; i<MAX ; i++)
{
cout << "enter a string " <<endl;
cin.getline(array[i], 80, '\n');
}
for(i=0; i<MAX; i++)
cout<<array[i]<<endl;
return;
}
and this works FINE ...
but when I have this:
Code:
#include <iostream.h>
#include<string.h>
void enter();
const int MAX = 3;
char array[MAX][81];
int i;
int main(void)
{
char answer;
cout<<"Enter 'E' to start entering text"<<endl;
cin>>answer;
if (answer=='E')
{
enter ();
}
return 0;
}
void enter()
{
for (i = 0; i<MAX ; i++)
{
cout << "enter a string " <<endl;
cin.getline(array[i], 80, '\n');
}
for(i=0; i<MAX; i++)
cout<<array[i]<<endl;
return;
}
...it only accepts 2 string instead of 3 ! (MAX=3). The output is like this:
Code:
Output: Enter 'E' to start entering text
Input : E
Output: enter a string
enter a string
//it goes weird here, the message is display twice, skip array[0]
Input : 1st string
Ouput : enter a string
Input : 2nd string
Displays:
//nothing on this line
1st string
2nd string
what the heck is wrong? I tried using cin.ignore() to stop the message from displaying twice, but then strings are not saved properly if i use that.
This should solve ur problem
Code:
#include <iostream.h> // change this to new style
#include<string.h> // change this to new style
void enter();
const int MAX = 3;
char array[MAX][81];
int i;
int main(void)
{
char answer;
cout<<"Enter 'E' to start entering text"<<endl;
cin>>answer;
cin.ignore(); // Just added this. Since you are accepting the value
// in a character variable, the input stream still has
// the enter symbol. Just flush it out.
if (answer=='E')
{
enter ();
}
return 0;
}
void enter()
{
for (i = 0; i<MAX ; i++)
{
cout << "enter a string " << endl;
cin.getline(array[i], 80, '\n');
}
for(i=0; i<MAX; i++)
cout<<array[i]<<endl;
return 0; // added 0 here
}
