What is the difference between n=1 and n==1 in the C language?

'=' 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;

} 

thank u

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.

yes!

As my tutor Shri Badri Gopi Krishna sir said, =  operator is used to assigne a value to a variable. 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 

= and ==  both are operators in c. The = sign is known as assignment operator wehreas == is known as  logical operator.

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.
