I want to compare two strings i use a code similar to the following one but its not working

int main (void){
  char function[100]="my_Name";
  char myType[50]={0};
  char myNumber[50]={0};
  sscanf(function, "%[^_]%*c%[^_]%s",myType,myNumber);
  if (myNumber=="Name")
  {
    //do stuff
  }
  return 0;
}

my ifcondition is not verified, How can I solve my problem?

hah, no `==` for strings, please. use `strcmp()`. – Sourav Ghosh Aug 16 '17 at 07:19

`if (strcmp(myNumber, "Name") == 0)` – Support Ukraine Aug 16 '17 at 07:21

Also always check return value of any `*scanf` functions, as a habit. It can save a lot of grief and grey hair. – hyde Aug 16 '17 at 08:08
How to check `*scanf` return value and what if i Want to do `switch(myType)` knowing that switch can take only interger walues ? – MrsIl Aug 16 '17 at 09:12

`"%[^_]%*c%[^_]%s"` requires three arguments for input. Argument is insufficient. This will probably cause segment faults. – BLUEPIXY Aug 16 '17 at 11:47
