Comparison between point. and int

Question

When I type hk on the Output, it did not say HONG KONG, It just say INPUT ERROR everytime.

char dc,ds[15];
int main(int argc, char *argv[]) {
p("Destination Code: ");
s("%s", &dc);

if(dc=="hk"){
    strcpy(ds, "HONG KONG");
}
else{
    strcpy(ds, "INPUT ERROR");
}

p("Destination: %s", ds);
return 0;

Two problems here.

You have declared dc as char type and trying to read in the string type.
You cannot use == to compare two strings, you should use strcmp instead.

Example:

  char dc[3];    
  scanf("%2s", dc);
  if(strcmp(dc,"hk") == 0){
    strcpy(ds, "HONG KONG");
  }
  else{
     strcpy(ds, "INPUT ERROR");
  }

So. What am I going to change?? – Kokie Oct 01 '18 at 12:47
@Kokie You should declare `dc` as `char` array and use `strcmp` to compare the `string` instead of `==`. Refer the example section in the answer. – kiran Biradar Oct 01 '18 at 12:51
