2. Post any realated code with the problem.
3. Wait until someone like me, who is a genius, to help you with your problem ;).

Thanks!!!!
I would be a lot recognizing if you help me for this problem:
I have a text file and I would be searching on this file some word of this type "wordi" where i is a natural number. Since these words come written on this file second of a sure number j (that indicate the number of the inputs) es. j=2 in the file I'll find word1 and word2, I have tried to do a for cicle but I don't succeed to do a concatenation of the string (word) and the number (j).
Can you help me? :idea: :idea:
Thank you
PS. Excuse me for the english!!!! ;)

Within the file you are using all data is binary. When the file data is read into your program, your program converts that data into whatever it's been told to convert it into based on what variable is going to hold the information in the program. To concatenate to variables you can use a variety of techniques based on what the variable types are. If the variable types are both null terminated strings you can use strcat() to combine them into a single string. If the variables are both instances of the STL string class you can use the + operator to concatenate them. If one variable is a null terminated string and the other is a numerical variable you can use ssprintf() to concatenate them. If one variable is an instance of the STL string class and the other is a numerical variable you can use an istringstream to concatenate them. And so on.

Thank you, I have resolved this problem using the sprintf function!!!
Now I have another problem. I have a function that search a string in a text file. This function return an int: 0 if the string I must be search isn't in the file, 1 otherwise.
The problem is: if the searching string is "input1" and in the file there is a string "counter_input1" the function return 1 instead must be return 0.
