hi i wrote this code which is written bellow when ever i check the value of u it appear to be the 3. while it is supposed to be 8. Can any body tell me what is the problem with this code and how can i get the exact size of the arrgument of func.
void main(){ func("fara.txt"); } void func(unsigned char arr[]){ int u; u=sizeof(arr); }
That is not an appropriate use of sizeof. Try using strlen. Jon
"Try using strlen." Assuming that we're talking about null-terminated strings...
int u,v; u = sizeof( "Hello World\n" ); v = strlen( "Hello World\n" );
"It is left as another excercise for the student to explain why u and v receive different values in the above example..." In case the student is left even more confused by this: u==13 //Includes null terminator v==12 //Doesn't include null terminator
