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 at least count+1 characters.

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!", 15);
    std::puts(str);
}

Output:

Hello World! Go
