Can someone explain the concept of pre and post increment in C?

Please explain ++i and i++ use with example. It confuses me many times, which one increment its value first and when assigned?

• Pre and Post increments are operators used in c language.In Pre increment operator(++a),the value of the variable is modified(incremented) first and then its value is assigned to the variable.egbr /int a=2;br /++a;br /printf("%d",a);br /Output:3br /In post increment operator(a++),the value is first assigned to its variable and then modified(increased).br /eg. int a=2;br /a++;br /printf("%d",a);br /Output:2

• ++i is pre increment operator and i++ is a post increment operator in ++i first i is incremented to i+1 and its value is fetched . in i++ first value of i is fetched then i is incremented to i+1 after execution i.e. incremented value effect can be seen in next statement . let us consider an example where int i=10; int j =i++; //j will contain value of =10 and i will we incremented to 11 vs int j = ++i; // i will be incremented first and then its value will be assigned to j i.e j will contain 11.
