Appends a byte string pointed to by src to a byte string pointed to by dest. The resulting byte string is null-terminated. If the strings overlap, the behavior is undefined.

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

#include <string.h> 
#include <stdio.h>
 
int main() {
    char str1[50] = "Hello ";
    char str2[50] = "World!";
    strcat(str1, str2);
    printf("%s\n", str1);
}
