The meaning of a*b in C

In C, a*b represents the multiplication of a and b Operation.

Detailed description:

• a and b are both operands, which can be integers, floating point numbers or expressions.
• • is the multiplication operator, used to calculate the product of operands.
• The multiplication operator has higher precedence than the addition and subtraction operators.
• If a or b is zero, the result is zero.

• For negative numbers, the multiplication operation follows the following rules:

  • Positive number * Positive number = Positive number
  • Positive number * Negative number = Negative number
  • Negative number* Negative number = Positive number

Sample code:

<code class="cpp">int a = 5;
int b = 3;

int result = a * b; // result = 15</code>

A few points to note:

• The multiplication operator only works on numeric types.
• The associativity of the multiplication operator is left associative, which means that the multiplication operations in the expression are evaluated from left to right.
• In C, the multiplication operator is different from the pointer operator. Pointer operator (*) is used to dereference a pointer variable and get the value pointed to.
