{
printf("\nab");
printf("\bsi");
printf("\rha");
}



output is hai

thats why i asked this question it was given in a test of some software company, there were many others ques like this


thanks for ur reply

the complete problem is like this


void main()
{
int a=1,b=2,c=3,d=4,e;
e=(a,a)+(b,c)+(c,d)-(d,b);
printf("%d",e);
}

Yes this is an algebric expression if it was like (a*b) i know how to solve that
but dunno how to solve expressions involvins commas

c= (a,b)+(b,c)-(a,b)*(c,b);
if a,b,c are respectively 1,2,3
