unsigned/signed problem

[Sukhbir]

consider the programme

void main()
{
unsigned i=1;
signed j=-1;
if(i<j)
printf("less");
}

output is:
less
why can someone explain me

hi sukbhir
which compiler u r using?
some times it depends on the compiler.
in c lang. conditional operators compares signed values.

try this...

#include<stdio.h>

main()
{
unsigned int i=1;
signed int j =-1;
if((signed)i<j)
printf("less");
else
printf("greater");
}

You are comparing signed and unsigned values. The signed value gets promoted to an unsigned value for the comparison and ends up being very large.
