Replicate the standard string library function strcat().

#include <stdio.h>

void fnstrcat(char *, char *);

int main(void)
{
char name[80], surname[40];

printf("\nEnter a name : ");
gets(name);
printf("\nEnter surname : ");
gets(surname);

fnstrcat(name, surname);

printf("\nFull name = %s", name);

return 0;
}

void fnstrcat(char *dest, char *src)
{
for( ; *dest != '\0' ; dest++);

for( ; *src != '\0' ; src++)
{
*dest = *src;
dest++;
}
*dest = '\0';
}
