Assignment operators in C:

    • In C programs, values for the variables are assigned using assignment operators.
    • For example, if the value “10” is to be assigned for the variable “sum”, it can be assigned as “sum = 10;”
    • Other assignment operators in C language are given below.
Operators
Example
 Explanation 
Simple assignment operator
=
sum=10
10 is assigned to variable sum
Compound assignment operators
+=
sum+=10
This_is_same_as_sum=sum+10…………
-=
sum-=10
This is same as sum = sum-10
*=
sum*=10
This is same as sum = sum*10
/+
sum/=10
This is same as sum = sum/10
%=
sum%=10
This is same as sum = sum%10
&=
sum&=10
This is same as sum = sum&10
^=
sum^=10
This is same as sum = sum^10

Example program for C assignment operators:

    • In this program, values from 0 – 9 are summed up and total “45” is displayed as output.
    • Assignment operators such as “=” and “+=” are used in this program to assign the values and to sum up the values.
# include <stdio.h>
int main()
{
    int Total=0,i;
    for(i=0;i<10;i++)
    {
        Total+=i; // This is same as Total = Toatal+i
    }
    printf("Total = %d", Total);
}

Output:

Total = 45

Types of Operators
             Description              
1
 Arithmetic_operators These are used to perform mathematical calculations like addition, subtraction, multiplication, division and modulus
2
 Assignment_operators These are used to assign the values for the variables in C programs.
3
 Relational operators These operators are used to compare the value of two variables.
4
 Logical operators These operators are used to perform logical operations on the given two variables.
5
 Bit wise operators These operators are used to perform bit operations on given two variables.
6
 Conditional (ternary) operators Conditional operators return one value if condition is true and returns another value is condition is false.
7
 Increment / decrement operators These operators are used to either increase or decrease the value of the variable by one.
8
 Special operators &, *, sizeof( ) and ternary operators
