Increment operator in C
In C programming ++ is used as increment operator, Increment operator is used to increasing the value of a variable by 1, It is always used with a numeric type variable. It can be written in two ways.
variable ++
++ variable
The meaning of both types is the same i.e. variable=vaiable+1, Let's understand with examples.
Example 1
int a=20;
a++
printf("Now the value of a is %d",a);
Output
Now the value of a is 21
Example 2
int b=20;
++b
printf("Now the value of b is %d",b);
Output
Now the value of b is 21
Explanation-
In both examples you can see that, when we used a++ then it increases the value of a by 1, and when we used ++b then it also does the same thing i.e. it also increases the value of b by 1.
So simply
a++ means a=a+1
++b means b=b+1
