An assignment expression has the value of the left operand after the assignment. It's to allow things like this: a = b = c; (although there's some debate as to whether code like that is a good thing or not.) Incidentally, this behaviour is replicated in Java (and I would bet that it's the same in C# too).
What is the result of an assignment expression in C?
1. This is an infinite loop. It first assign 10 to c, then compare it with c > 0, then again loop starts, assign 10 to c, compare it with c>0 and so on. Loop never ends. This is equivalent to the following: while(c=10); /* Because c assign a garbage value, but not true for all cases maybe it assign 0 */. while(c);
Assignment Expressions (GNU C Language Manual)
7 Assignment Expressions. As a general concept in programming, an assignment is a construct that stores a new value into a place where values can be stored—for instance, in a variable. Such places are called lvalues (see Lvalues) because they are locations that hold a value. An assignment in C is an expression because it has a value; we call it an assignment expression.
c
0. Roughly speaking, in C; A statement is a section of code that produces an observable effect; An expression is a code construct which accesses at least one data item, performs some operation of the result of that access (or those accesses), and produces at least one result. An expression may be composed of (smaller) expressions.
Assignment operators
Assignment performs implicit conversion from the value of rhs to the type of lhs and then replaces the value in the object designated by lhs with the converted value of rhs . Assignment also returns the same value as what was stored in lhs (so that expressions such as a = b = c are possible). The value category of the assignment operator is non ...
Assignment Operators in C
Simple assignment operator. Assigns values from right side operands to left side operand. C = A + B will assign the value of A + B to C. +=. Add AND assignment operator. It adds the right operand to the left operand and assign the result to the left operand. C += A is equivalent to C = C + A. -=.
C Assignment Operators
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.
Expression Statement (GNU C Language Manual)
19.1 Expression Statement. The most common kind of statement in C is an expression statement.It consists of an expression followed by a semicolon. The expression's value is discarded, so the expressions that are useful are those that have side effects: assignment expressions, increment and decrement expressions, and function calls.
C Assignment Operators
Summary: in this tutorial, you'll learn about the C assignment operators and how to use them effectively.. Introduction to the C assignment operators. An assignment operator assigns the vale of the right-hand operand to the left-hand operand. The following example uses the assignment operator (=) to assign 1 to the counter variable:
Assignment Operators in C with Examples
Assignment operators are used to assign value to a variable. The left side of an assignment operator is a variable and on the right side, there is a value, variable, or an expression. It computes the outcome of the right side and assign the output to the variable present on the left side. C supports following Assignment operators: 1.
Assignment Operator in C
Let's discuss it here in detail. The assignment operator ( = ) is used to assign a value to the variable. Its general format is as follows: variable = right_side. The operand on the left side of the assignment operator must be a variable and operand on the right-hand side must be a constant, variable or expression.
C Programming Assignment Operators
There are two types of assignment operators in C: 1. Simple Assignment Operator (=) This assigns the value on the right-hand side (RHS) to the variable on the left-hand side (LHS). You can use a literal, another variable, or an expression in the assignment statement.
Assignment Operators in C
1. "=": This is the simplest assignment operator. This operator is used to assign the value on the right to the variable on the left. Example: a = 10; b = 20; ch = 'y'; 2. "+=": This operator is combination of '+' and '=' operators. This operator first adds the current value of the variable on left to the value on the right and ...

Using assignment as a condition expression?
The result of the assignment operation is the value stored in the left operand after the assignment has taken place; the result is an lvalue. The result of the expression a = 5 is 5. [6.4/4] [..] The value of a condition that is an expression is the value of the expression, implicitly converted to bool for statements other than switch.
C Operators
Comparison operators are used to compare two values (or variables). This is important in programming, because it helps us to find answers and make decisions. The return value of a comparison is either 1 or 0, which means true ( 1) or false ( 0 ). These values are known as Boolean values, and you will learn more about them in the Booleans and If ...
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.
Assignment Statement in C Programming Language
How to assign values to the variables? C provides an assignment operator for this purpose, assigning the value to a variable using assignment operator is known as an assignment statement in C. The function of this operator is to assign the values or values in variables on right hand side of an expression to variables on the left hand side.

You cant assign arrays in C. You only assign scalar types (integers, pointers, structs and unions) but not the arrays. Structs can be used as a workaround if you want to copy the array. char c[20]; struct bar b = {.c = "Hello World!!"}; struct bar x;
What alternatives are there for C/C++ assignment operator (=) and

Refactor your code with C# collection expressions
Collection expressions also allow you to assign to interfaces without stating an explicit type. The compiler determines the type to use for types, such as IEnumerable<T>, IReadOnlyList<T>, and IReadOnlyCollection<T>. If the actual type used is important, you'll want to state it because this may change if more efficient types become available.
C assignments in an 'if' statement
Basically C evaluates expressions. In. s = data[q] The value of data[q] is the the value of expression here and the condition is evaluated based on that. The assignment. s <- data[q] is just a side-effect.
