# Assignment Operators In C Programming

**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: +=, -=, *=, /=, %=, &=, ^= )

sum = 10; 10 is assigned to variable sum |

This is same as sum = sum + 10 |

This is same as sum = sum – 10 |

This is same as sum = sum * 10 |

This is same as sum = sum / 10 |

This is same as sum = sum % 10 |

This is same as sum = 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.

Assignment_operators | These are used to assign the values for the variables in C programs. |

These operators are used to compare the value of two variables. | |

These operators are used to perform logical operations on the given two variables. | |

These operators are used to perform bit operations on given two variables. | |

Conditional operators return one value if condition is true and returns another value is condition is false. | |

These operators are used to either increase or decrease the value of the variable by one. | |

&, *, sizeof( ) and ternary operators. |

An assignment operation assigns the value of the right-hand operand to the storage location named by the left-hand operand. Therefore, the left-hand operand of an assignment operation must be a modifiable l-value. After the assignment, an assignment expression has the value of the left operand but is not an l-value.

**Syntax**

*assignment-expression*:*conditional-expression*

*unary-expression assignment-operator assignment-expression*

*assignment-operator*: one of**= *=****–= <<= >>= &=**

The assignment operators in C can both transform and assign values in a single operation. C provides the following assignment operators:

Operator | Operation Performed |
---|---|

= | Simple assignment |

*= | Multiplication assignment |

Division assignment | |

Remainder assignment | |

Addition assignment | |

–= | Subtraction assignment |

<<= | Left-shift assignment |

>>= | Right-shift assignment |

&= | Bitwise-AND assignment |

Bitwise-exclusive-OR assignment | |

Bitwise-inclusive-OR assignment |

In assignment, the type of the right-hand value is converted to the type of the left-hand value, and the value is stored in the left operand after the assignment has taken place. The left operand must not be an array, a function, or a constant. The specific conversion path, which depends on the two types, is outlined in detail in Type Conversions.
