Write a C macro PRINT(x) which prints x

Here we will see how to define a macro called PRINT(x), and this will print whatever the value of x, passed as an argument.

To solve this problem, we will use the stringize operator. Using this operator the x is converted into string, then by calling the printf() function internally, the value of x will be printed. Let us see the example to get the better idea.

Example

#include <stdio.h>
#define PRINT(x) printf(#x)
int main () {
   PRINT(Hello);
   printf("
");
   PRINT(26);
   printf("
");
   PRINT(2.354721);
   printf("
");
}

Output

Hello
26
2.354721
