C++ strcat() Function

C++ strcat()

The strcat() function concatenates a copy of source string to destination string and terminates destination string with a null.

The null terminator originally ending destination is overwritten by the first character of source string.

If the array overlap, the behavior of strcat() is undefined.

Remember, no bounds checking takes place, so it is the programmer's responsibility to ensure that the size of the destination string variable is large enough to hold both its original contents and also those of source string.

Note: The source string (src) is untouched by the operation.

Example

C++ Compiler
#include <cstring> #include <iostream> using namespace std; int main() { char src[50] = ".com"; char dest[50] = "wikimass"; strcat(dest, src); cout << dest ; return 0; }

char *strcat(char *dest, const chart *src)
