  • To further achieve optimizations at architecture level we can use targets with pragmas. These optimizations can produce surprising results.
  • C #pragma. The #pragma preprocessor directive is used to provide additional information to the compiler.
  • By using #pragma startup directive we can call the functions on startup before main function execution #include<stdio.h>. void print1() { printf("Before Main 1\n")
