| char *strcat( char *dest, const char *src ); |
(until C99) | |
| char *strcat( char *restrict dest, const char *restrict src ); |
(since C99) | |
Appends a byte string pointed to by src to a byte string pointed to by dest. The resulting byte string is null-terminated.
The destination byte string must be large enough for the contents of both str and dest and the terminating null character.
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 |
Return value
dest
Example
Run this code
#include <string.h> #include <stdio.h> int main() { char str[50] = "Hello "; char str2[50] = "World!"; strcat(str, str2); strcat(str, " ..."); strcat(str, " Goodbye World!"); puts(str); }
Output:
Hello World! ... Goodbye World!
