I'm a novice in C. I would like to ask the ff:
- what is the return value of strstr function?
- Is there a substring function in Turbo C where you specify the string, the length of string to extract and the starting position?
- For instance, I have a char var TEMP, I'm storing letters I got from a loop. How do I initialize TEMP to return it back to NULL. I used TEMP=NULL but seems not working.
Please advice. Many thanks.
