      Macros using #define

      A macro is a fragment of code that is given a name. You can define a macro in C using the #define preprocessor directive. 

      #include<stdio.h>
      #define max 50
      int main()
      {
      printf(“max is %d”, max);
      return 0;
      }

      Output:
      max is 50
