[snakey]

How would i select a letter in a string and make it its own string? So say if i wanted to use the letter "a" in Snakey and make it its own string or even just have an if statement that uses the letter you select.

[jollyrancher82]

char* string = "snakey";

if (string[2] == 'a')

{

// foo...

}

Hmmm not really what im after say i have "string x" and x=snakey how do i use the a as a seperate string. So i'll have int x = snakey then i'll make int y which will = a.

P.S. i dont no what x is at the start it gets entered as an input and i use each letter individually if that helps any.

if you use

char* x = "snakey";

x[0] will be s

x[1] will be n

x[2] will be a

x[3] will be k

x[4] will be e

x[5] will be y

is that what you mean?

I'm sure there's a built in function for it, I have done it in Java, but not C++, sorry.

    string str1( "Alpha Beta Gamma Delta" );
    unsigned int loc = str1.find( "Omega", 0 );
    if( loc != string::npos )
      cout << "Found Omega at " << loc << endl;
    else
      cout << "Didn't find Omega" << endl;

That does what you want on the side... just change the "Omega" to the character, and use the character position that is returned to substring(Java) whatever you want out.

Read under the "find" command here:

SomeoneE1se has done it thanks man

easier way would be to do a loop then you could loop through for any thing.

something like:

while stringx != '0'{

if stringx = x

strcpy( stringx, newString);

i++;

}

just off the top of my head, this wont work of course but it gives you an idea.

what does that do

I know I just woke up but HUH?

Wow, just wow... that's so wrong.

#include <string>

using namespace std;

string word1 = "snakey";

string word2 = "";

for(int x=0; x<word1.length(); x++)

    if(word1[ x ] == 'a')

          word2 = word1[ x ];

Take a look at strcpy_s .....
