@Team Bi.
int a=2,b=3,c;
a=(b++)+(++b)+a;
c=a>b?a:b;
b=(a++)+(b--)+a;
c=c++*b--
The value of a=11, b=25, c=260.
int a=2,b=3,c;
a=(b++)+(++b)+a;
c=a>b?a:b;
b=(a++)+(b--)+a;
c=c++*b--
The value of a=11, b=25, c=260.

If a=48, b=13; find a+=b++*5/a++ +b.

When this *for*loop will terminate?
for(a=1;scanf("%d",&a);a++)
printf("%d",a);
for(a=1;scanf("%d",&a);a++)
printf("%d",a);

int x=3,y,z;
z=y=x;
z=y+=x=-z;
printf("%d%d%d",x,y,z);
For this code, I get the output as -3 0 0.
But, I can't understand the real execution.
Anyone can explain?

The above program or logical operation output is 35 because prefix first increment then print and postfix first print then increment. They use one postfix and two prefix.
