see i want an explanation, can you help me to understand?
int a=5,b=10,d;
d=(a,b);
if d is printed the value of d is 10. I just want to know that d=(a,b); what it evaluates?

My Dear The Exate Coding is :- void main() -> int a,b,c,d: -> a=5,b=10,c=++a-b; -> printf("%d",a,b,c); & Output 4 it :- a=6,b=10,c=4
