Difference between assignment and equal to operators

Many times this question arises what is the difference between = and == operators in C programming language ? Here we are going to tell you exactly what the difference between these two operators are.

Assignment Operator (=)

= is an assignment operator in C, C + + and other programming languages, it is Binary Operator which operates on two operands.

= assigns the value of right side expression or variable to the left side variable.

See example-

x=(a+b);

y= x;

---

Here, when first expression evaluates value of (a+b) will be assigned into x and in second expression y=x; value of variable x will be a sign into y.

Equal to operator (==)

== is an equal to operator in C and C ++ only. It is binary operator which operates on two operands.

== compares value of left and right side expressions, return 1 if they are equal else it will return 0.

See example-

int x,y;

x=10;

y=10;

if (x==y)

printf (“true”);

else

printf (“false”);

---

Here, when expression x==y evaluates, it will return 1 ( it means condition is true) and true will print.
