C++ programming?

int strcmp(const char *s,const char *t)


{


int i;


for (i = 0; s[i] == t[i]; i++)


if (s[i] == '\0')


return 0;


return s[i] - t[i];


}





and NOT





for (int i = 0; s[i] == t[i]; i++)


????


the compiler says obsolete binding...?

C++ programming?
in the for(int i=0 ...)





you want to use the i variable outside the scope (i is available only into the scope of for statement)





Do you use an old book to learn C++ ? or a book based on draft ?
Reply:If you define int i within a (for) loop you have to define it again in subsequent loops otherwise you will get the error.


So


int main()


{


for (int i = 0; i %26lt; 10; ++i )


;


for (i = 0; i %26lt; 10; ++i )


;


}





// is wrong





int main()


{


for (int i = 0; i %26lt; 10; ++i )


;


for (int i = 0; i %26lt; 10; ++i )


;


}





// is correct.
Reply:try declaring i out side the strcmp scope
