Compiling program within another program using gcc

From command line i am getting file name which i have to compile using gcc. lets say its like this.

./a.out fileToBeCompiled.c

Then how i can compile this file using gcc within my program? lets say main.c for which a.out is being made.

From stackoverflow itsaboutcode

• You can always call gcc to compile from an shell execution command within your program.

  Reference to the system function.

  itsaboutcode : Thanks, it work for me.

  ammoQ : Using system is a bad idea, but if it works for itsaboutcode, it shall be fine with me
  From monksy

• Just exec gcc from within you program.

  int main(int argc, char** argv)
  {
     execv("/usr/bin/gcc", argv);
  }
  

  From stimms

• Learn how to call fork(), exec(), and wait(). You probably want to use execv() for this purpose.

  From D.Shawley

• ./a.out fileToBeCompiled.c && gcc fileToBeCompiled.c
  

  If ./a.out fails (it it returns something other than 0) gcc will not be called
