    having trouble to print helo world....

    I am using a mac, and I wrote a simple code using Xcode

    Code:
    #include <stdio.h>
    int main () {
       printf ("hello world\n");
       return 0;
    }
    I saved it as testing.c then I go to terminal and compile it
    gcc testing.c

    then it gives me the following error:
    testing.c:1:19: error: stdio.h: No such file or directory
    testing.c: In function ‘main’:
    testing.c:5: warning: incompatible implicit declaration of built-in function ‘printf’

    how come...?

    I know nothing about Apple products, such as Mac OS, so I can't provide specifics. However, you get this message because you don't have the development packages installed or setup properly. On Linux (Ubuntu in particular), you can install the "build-essentials" package I think it is called. Maybe try re-installing XCode, ensuring "all" features/libraries/development tools are also installed. Otherwise, search around for what required development package you need to install, specific to your OS.
