A.15 Comparison with FORTRAN

Many simple C functions are similar to FORTRAN function subroutines as shown in the example below:

A simple C function	An equivalent FORTRAN function
int myfunction(int x)	INTEGER FUNCTION MYFUNCTION(X)
{
int x,y,z;	INTEGER X,Y,Z
y = 11;	Y = 11
z = x+y;	Z = X+Y
printf("z = %d",z);	WRITE (*,100) Z
return z;	MYFUNCTION = Z
}	END
