Code:
char sentence[200], word[200]; char* occurs_at; int location; [i]//code to get user inputs for: sentence and word, then:[/i] occurs_at = strstr(sentence, word); [i]//a pointer (to somewhere in sentence)[/i] if(occurs_at) [i]//if true[/i]

According to link, strstr returns a pointer to first occurrence of the search word in the given sentence. So you could test something like this:

Good point! In my defence though, he used a string literal ("...") and those are null-terminated, so when reached, the while will loop will evaluate to false.Leave a comment:

When you declare a static array, you can do either of the following:
...Code:int arr1[3] = {1,2,3}; // or int arr1[3]; arr1[0]=1; arr1[1]=2; arr1[2]=3; int arr2[] = {1,2,3}; //compiler creates array of 3 and initialises them with the given values char arr3[] = "hello world!"; //compiler creates char array of length 12+1. the last character being the '\0' to indicate end of char array (this is a special case), and initialisesLeave a comment:

Actually, u can modify the while(...) test too. Use while(name[i]), when the end of string is reached, name[n-1] will return '\0' which just evaluates to false and the while loop exits, either that or the if(...) test will take care of the exit when it encounters a punctuation character....Leave a comment:

question on complicated pointer/reference declarations
I came across some strange declarations and am trying to get the hang of it. Any comments on how to read and use such decl. will be most welcomed.
1) Not sure if i understand this one. It could be that function f can be used to increment the address of a pointer. So to use f(...) give it an argument of type: int*
2) I got this one from pg35 of "C++ in a nutshell,"...Code:void f(int*& i) { i++; } -
I used the OpenCV library, it's all C functions. Very easy to load, modify (draw, text etc...) and display images....Leave a comment:

brrrr.... Look Dries, you should appreciate that someone actually volunteered to help. On another note, I think Cats has a good solution to try out.
(Besides the external location of your functions), it seems that you can get the desired function name (and arguments) from a user. Unfortunately this is only in string/char representation and can't be directly converted into a function name at runtime (if u can do that, let me know plz)....Leave a comment:

Well spotted weaknessforcats ! Also thank you Raghuram. Cheers guys. T....Leave a comment:

I wrongly copied & pasted my code. Sorry about that, but that's not the problem. I can't initialise the inherited structure using ={.,.,..};...Leave a comment:

Have u tried anything? Bubble sort perhaps, very easy 101 stuff....Leave a comment:

Initialising struct in C++
I was playing around with struct and realised that when i inherit from a base-class, i can no longer initialise the inherited struct the way i'm used to.
...Code:struct Date{[indent]int dd, mm, yy;[/indent] } struct Employee{[indent]char* fname, *lname; Date hiring_d; short dept; [/indent] }; struct Manager : public Employee{[indent]short level; //i've tried commenting this line for furher testing but no luc[/] -
Just a quick check. Does the following sound ok to anyone? It works, but i don't know whether the array gets de-allocated after main() ends?
...Code:#include <iostream> int main() {[INDENT] char* fname[3]; fname[0] = "aaa"; fname[1] = "bbb"; fname[2] = "ccc"; for(int i=0; i<3; i++) std::cout << "\n"[/]Leave a comment:
