C Assignment Operators
- 6 contributors
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 isn't an l-value.

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

The += assignment operator is a combination of + arithmetic operator and = simple assignment operator. For example, x += y; is equivalent to x = x+y;. It adds the right side value to the value of left side operand and assign the result back to the left-hand side operand. #include <stdio.h> int main () { int x = 100, y = 20, z = 50 ...
