    Hello every body..

    i have a question in C about :

    how can i search a string inside another string and count the number of the occurrences of that string ?

    You can use substr to find the first instance of a substring within a string. Repeatedly call this function on the new starting position until it fails, to count the number of occurrences.

    I think you mean strstr not substr.

    Yeah, messed that up...in C++ you would use string.find and string.substr, but in C you have strstr.
