Study Notes
Arithmetic Operations in C
- In C, the expression
5 + 3 * 2evaluates to11. This is because the multiplication operator (*) has higher precedence than the addition operator (+) in C, so the multiplication is performed first. - In C, the
++operator increments a value by one. It can be used as a pre-increment operator (++x) or a post-increment operator (x++). - The
==operator is used to compare two values for equality in C. It returnstrue(non-zero) if the values are equal andfalse(zero) otherwise. - After executing the code
y = 5; y *= 2;, the value ofywill be10. The*=operator is the compound assignment operator for multiplication in C. It assigns the product ofyand2back to the variabley.
