Multiplication in C Programming Language

In programming, multiplication is an essential arithmetic operation that is often used in many applications. In C, multiplication is performed using the * operator. In this guide, we will explore multiplication in C programming language and provide various examples.

Multiplication Operator

The multiplication operator in C is represented by the * symbol. It can be used with two operands to produce the product of two numbers. For example,

int a = 3;
int b = 4;
int c = a * b; // c = 12

In the above code, we declare two integer variables a and b and assign them the values 3 and 4, respectively. We then use the * operator to multiply a and b and store the result in the integer variable c.

Multiplying by Constants

In C, we can multiply a variable by a constant value. For example,

int a = 2;
int b = a * 5; // b = 10

In the above code, we declare an integer variable a and assign it the value 2. We then multiply a by the constant value 5 and store the result in the integer variable b.

Multiplying Floating-Point Numbers

In C, we can also multiply floating-point numbers using the * operator. For example,

float a = 1.5;
float b = 2.5;
float c = a * b; // c = 3.75

In the above code, we declare two floating-point variables a and b and assign them the values 1.5 and 2.5, respectively. We then use the * operator to multiply a and b and store the result in the floating-point variable c.

Multiplying with Assignment

C also provides a shorthand way to perform multiplication with assignment. For example,

int a = 4;
a *= 3; // a = 12

In the above code, we declare an integer variable a and assign it the value 4. We then use the *= operator to multiply a by the constant value 3 and store the result back in a.

Conclusion

In this guide, we explored multiplication in C programming language. We learned about the * operator, multiplying by constants, multiplying floating-point numbers, and multiplying with assignment. These concepts are essential to creating and developing C programs that involve arithmetics.
