Logical assignment operators

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;”
• There are 2 categories of assignment operators in C language. They are,
  1. Simple assignment operator ( Example: = )
  2. Compound assignment operators ( Example: +=, -=, *=, /=, %=, &=, ^= )

Operators	Example/Description
=	sum = 10; 10 is assigned to variable sum
+=	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.

C

1 2 3 4 5 6 7 8 9 10 11

# 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
