What is the difference between = and == in C programming?

The = and == operators are used for distinct things in C programming.

The assignment operator, often known as the = operator, is used to assign a value to a variable. Consider the following code as an example:

int x;

x = 5; 

The = operator is used in this code to assign the value 5 to the variable x. This means that x is now equal to 5.

The == operator, on the other hand, is known as the equality operator and is used to compare two values for equality. Consider the following code as an example:

int x = 5; 

if (x == 5) 

printf("x is equal to 5n");

The == operator is used in this code to compare the value of x to the value 5. If the two values are equal, the code contained within the if statement is run, and the message "x is equal to 5" is printed.

To summarise, the = operator is used for assignment, whereas the == operator is used for value equality comparison.
