MIXED - Mixed Language Programming

MIXED contains some simple examples of mixed language program. Particular examples demonstrate how a C main program can call a FORTRAN subroutine, and vice versa.

Problem 1 shows how a C main program can call a FORTRAN subroutine. Files you may copy include:

• prob1_main.c, C main program;
• prob1_sub.f90, the F90 subroutine;
• prob1.csh, the compilation and execution commands;
• prob1.out, the output of running the program;

Problem 2 shows how a FORTRAN main program can call a C routine. Files you may copy include:

• prob2_main.f90, the F90 main program;
• prob2_sub.c, C subroutine;
• prob2.csh, execution commands;
• prob2.out, output;

Problem 3 shows how a C main program can call a FORTRAN routine, passing data of various kinds back and forth. Files you may copy include:

• prob3_main.c, the C main program and routines;
• prob3_sub.f90, FORTRAN 90 subroutines;
• prob3.csh, execution commands;
• prob3.out, output;
