Convert C/C++ program to Preprocessor code
We use g++ compiler to turn provided Cpp code into preprocessor code. To see the preprocessor code generated by the CPP compiler, we can use the “-E” option on the command line:
Preprocessor include all the # directives in the code. and also expands MACRO function.
g++ -E filename.cpp
#define MAX 10
a = MAX, b = MAX;
c = a + b;
Running the command:
g++ -E geeks.cc
int a = 10, b = 10;
// Add two values.
int c = a + b;
