Define Macro PRINT to print given integer argument in C | C preprocessor programs

As we have discussed in the last post (how to use printf in function like macro?) that we can use printf() in Macros.

Here, we have to define a Macro that will accept an argument and print it by using printf() function.

Macro definition:

    #define PRINT(val) (printf("value is: %d\n",val))
