int var1=1;
float var2=2.3;
printf("%d %f:n",var1,var2);
results in:
1 %f
Can anyone tell me why this is happening. I'm using Lattice C 5.10.dewolfe@ug.cs.dal.ca (Colin DeWolfe) (02/01/91)

I'm using Lattice C 5.10. You're linking with the wring library. When you use floats and such, use lcm.lib (or lcm881.lib depending on your math mode) instead of lc.lib or if you're doing "lc -L file", change it to "lc -Lm (or -Lm881) file" -- Colin DeWolfe dewolfe@ug.cs.dal.ca

I'm using Lattice C 5.10. You'll be using the printf() defined in amiga.lib. That version doesn't handle %f or %d and a number of other capabilities of the printf() we all know and love to use. Use "#include <stdio.h>" and "fprintf(stdout,"%d %f:n",var1,var2);" to get the result you expect. - Alexander Elkins (aoe@hpfiaoe.fc.hp.com)

I'm using Lattice C 5.10. I don't know much about SAS C (I'm using Atzec 3.6a), but you should explicitly link with the math library before standard C-library (amiga.lib). As Floating-point-code is larger than integer-code and floats are not often used, standard library-code is for integers and you have explicitly to say, that you want the float-code. -Heiko P.S.: Consult your manual about printf("%f"); -- Heiko W.Rupp, Gerwigstr.5, D-7500 Karlsruhe 1 | hwr@pilhuhn.ka.sub.org Tel: +49 7021 693642 (voice only) | uk85@dkauni2.bitnet Fresst Scheisse, Miliarden von Fliegen koennen nicht irren !

Since the "%f" gets printed, the problem is more likly that you are linking AMIGA.LIB before lc.lib. There is a "printf()" defined in amiga.lib but it does not understand floats. So... link with lc.lib then amiga.lib.
