'=' is used to initialized value to a variable  (ASSIGNMENT operator  )

'==' is relational operator which is used to compare with two variables  in If condition statements

example n=1; in this statements 1 will be assign to variable n

next , n==1;

here it will check ...is n equal to  1 or not  ;

if it is equal it will return true value or it will execut if statement

if(n==1) // it is true so it executs statement

{

statement;

'=' is the most commonly used assignment operator. An assignment operator is used for assigning a value to a variable.

So n=1 means variable n is assigned with value 1.

 

whereas '==' means an equal to operator which is a relational operator. A relational operator checks the relationship between two operands. If the relation is true, it returns 1; if the relation is false, it returns value 0. Relational operators are used in decision making and loops.

So n==1 means it's checked whether the variable n holds the value 1.

1. n=1 means assigning 1 to n. 2. n==1 means comparing n with 1. Eg: if(n==1) n value is 1 condition is true and if condition is also true condition will execute i.e output is 1. n value is other than 1 if conidition is false condition will not work. i.e. output is 0. read more

1. n=1 means  assigning 1 to n.

2. n==1 means  comparing n with 1.

    Eg: if(n==1)

n value is 1 condition is true and if condition is also true condition will execute i.e output is 1.

n value is other than 1 if conidition is false condition will not work. i.e. output is 0.

The assingment operator is used to assign a vaule (or varibale) to a variable. For example, n=1 (or n=a). This means that the vaule of n is 1.

The == operator is used for logical opearation. For example if(n==1), that is the value of n is compared to 1, if it is true i.e n is equal to 1, then true statements are executed else false statements are executed.

By using it a value will be stored in the memory of a variable, and == operator is used to compire a value with another i.e. compire L (Left side) value with R (Right side) value. We can also check the values stored in two variables are equal or not like (a=b=1;) to check is both a and b has same value or not we can use ( a==b  ) if both are equal value it returns True else False we can use this == operator morly with IF condition

n=1 means. you are assigning value 1 to n. value 1 is stored in variable n. = is an assignment operator where as n==1 means you are checking for equality. It checks whether value of n equls to 1. == is relational operator
