C++ Compare char array with string

Question

I\'m trying to compare a character array against a string like so:

const char *var1 = \" \";
var1 = getenv(\"myEnvVar\");

if(var1 == \"dev\")
{
   // do stu         


        

Answer 1

In this code you are not comparing string values, you are comparing pointer values. If you want to compare string values you need to use a string comparison function such as strcmp.

if ( 0 == strcmp(var1, "dev")) {
  ..
}
