Hi,I wonder how to connect 2 strings in c++ under Unix? I tried strcat,and the code got stuck(no compiling error,though). This is what I'm doing: char* s1="bin"; char* s2="***"; ... cout<simply doesn't work! The execution stops at the strcat.

You need to allocate space if you are going to do it the C way. There is a string type in C++. #include // note not string.h #include using namespace std; main () { string s1 = "bin "; string s2 = "liner"; string s3 = s1 + s2; cout << s3 << endl; return 0; } Should give you "bin liner"

The includes were string iostream There is a problem with angle brackets in this forum.

Got it.Thanks. Sorry another basic question: what's the essential difference between string and char* or char[]? For example,if I define char[20] path,then assign "/bin/" to it,the compiler complains that the constant char[5] doesn't match the string.
