Question

C Question: I apologize for this long size post, but I wanted to explain the way of doing it. Kindly HELP me .

Question is:

implement char *mystrcat(char *dest, const char*src)  

adds a copy of the string src onto the end of the string starting at dest. The first char is src is put at the location of the 0 at the end of string dest. Returns dest

Could you please implement / write the code in the same way I have written for " *myindex(const char *s, int c) "

I made 2 files, name: mn3.c and my3.c for *myindex(const char *s, int c) . Please make same kind of 2 files, you cane give name like mn2.c & my2.c ( Or anything you want). There kindly implement char *mystrcat(char *dest, const char*src)

It adds a copy of the string src onto the end of the string starting at dest. The first char is src is put at the location of the 0 at the end of string dest. Returns dest.

SAMPLE CODE :

The code for mn3.c is:

#include

char * myindex(const char *s, int c);

int main()
{
//char *str = "dogcat";
char str[] = "dogcat";
char *p = myindex(str, 'X');
if (p!=0) printf("%d\n", p-str);
else printf("Not Found\n");

p = myindex(str, 'c');
if (p!=0) printf("%d\n", p-str);
else printf("Not Found\n");

*p = 'X';
printf(str);
}

And the code for my3.c is:

char * myindex(const char *s, int c)
{
while (*s !=0) {
if (*s==c)
return (char *) s; //(char *) is a cast
s++;
}
return 0;
}

char * myrindex(const char *s, int c)
{
char *r=0;
while (*s !=0) {
if (*s==c)
r=s;
s++;
}
return r;

}

Above- I made 2 files, name: mn3.c and my3.c for *myindex(const char *s, int c) . Please make same kind of 2 files, you cane give name like mn2.c & my2.c ( Or anything you want). There kindly implement char *mystrcat(char *dest, const char*src)
