std::strncat
Defined in header <cstring>
|
||
char *strncat( char *dest, const char *src, std::size_t count ); |
||
Appends a byte string pointed to by src
to a byte string pointed to by dest
. At most count
characters are copied. The resulting byte string is null-terminated.
The destination byte string must have enough space for the contents of both dest
and src
plus the terminating null character, except that the size of src
is limited to count
.
The behavior is undefined if the strings overlap.
Parameters
dest | - | pointer to the null-terminated byte string to append to |
src | - | pointer to the null-terminated byte string to copy from |
count | - | maximum number of characters to copy |
Return value
dest
Example
Run this code
#include <cstring> #include <cstdio> int main() { char str[50] = "Hello "; char str2[50] = "World!"; std::strcat(str, str2); std::strncat(str, " Goodbye World!", 3); std::puts(str); }
Output:
Hello World! Go
