Question

I have a problem with this. Here’s the specific part of my C code:

unsigned char *p;
char s[1048];
int m[1048], r[2];
int e = 0, L = 0, mov = 0, ri, i;
for(*p = s; *p; ++p, mov += m[L++])
       m[L] = min(*p - 'A', 'Z' - *p + 1);

Now i got the message – assignment makes integer from pointer without a cast. Please help me out.

Answer 1

s is an array of type char, you assign it to the dereferenced p which is a pointer of ‘unsigned char’. You cannot do this without casting s:

The code that you probably want is:

for(p = (unsigned char *)s; *p; ++p, mov += m[L++])

by incrementing p in the for loop you go through all the values in the array s
