    Definition?

    Can any one define this (and its utility) for me, as concretely as possible? It is include in my code and only returns an error.

    char * pch;
    "Nay! But you love the present life!"

    Its a pointer to a char. My advice: don't deal with pointers until you get to them in your study of C++.
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    error:

    full piece of code snippet:
    Code:
    char * pch;
    pch=strstr (str, 'good');
    related error: "arguement of type "int" is incompatible with parameter of type "const char" *

    Code:
    #include <stdio.h>
    #include <fstream>
    #include <iostream>
    #include <string.h>
    #include <windows.h>
    
    using namespace std;
    
    int main()
    {
    char str[]="good"; 
    char grabber[256];
    
    
    cout<< "Hello, how are you today?\n"<< endl;                     
    cin.getline(grabber,256);
    
    char * pch;
    pch=strstr (str, 'good'); //Searching for “good” in  ^ Char str
    
    
    if(pch !=NULL) 
    
    cout<< "I am glad to hear you are doing well today."<< endl;                      
    else
    cout<< "Is anything wrong at all? Would you like to discuss it? \n"<< endl;                      
    
    
    
    Sleep(50000);
    
    return 0;  //END

    Ah,

    A simple error:
    Code:
    pch=strstr(str, 'good');
    Try changing the pair of single quotes ('') to double quotes ("").

    The function strstr() takes a string [array of characters] for the second argument. By sending 'good', that can cause simple issues because the single quotes are to define a single character while the double quotes define an array of characters.

    Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.

    Does strstr() return an integer? Sounds like it does. You do seem to be trying to cover alot of c++ material at once. Take Zach's suggestion.

    [edit]
    nevermind, seems Stack Overflow solved the problem. strstr() doesn't return an int. I didn't even catch that S.O., just looked at the error.
