Thanks for the reply sir. But i am still stuck with
the same old problem since the system() function isn't
working & the manpages aren't of much help either.
Giving below an account of what my programs are &
their output:
####PERL PROGRAM####
#assign.pl#
#!/usr/bin/perl
use strict;
use warnings;
print "enter the first number\n";
my $x = <STDIN>;
chomp $x;
print "enter the second number\n";
my $y = <STDIN>;
chomp $y;
my $z = system("assign.f",'$x','$y');
print "Output of the two numbers is:\n";
print $z,"\n";
exit;
#output#
>$perl assign.pl
enter the first number
2
enter the second number
4
Can't exec "assign.f": Permission denied at assign
line 10, <STDIN> line 2.
Output of the two numbers is:
-1
#####FORTRAN PROGRAM#####
c assign.f
WRITE(*,*) "ENTER FIRST NUMBER"
READ(*,*) x
WRITE(*,*) "ENTER SECOND NUMBER"
READ(*,*) y
z = x+y
WRITE(*,*)z
END
#output#
>$g77 assign.f
>$ ./a.out
ENTER FIRST NUMBER
2
ENTER SECOND NUMBER
4
OUTPUT OF THE TWO NUMBERS IS:
6.
Can you suggest sir what should be my approach to this
problem. Waiting for an early response from you.
Thanking you..
