# Introduction to Pointer Arithmetic

### Moving Pointers

You can use arithmetic operators like addition (`+`

) and subtraction (`-`

) with pointers **to navigate through memory locations**. When a pointer is pointing to an *int*, increasing its value will move it forward by the size of an integer.

**The size of the data type** to which the pointer points **determines the step size** of the arithmetic operation. You can experiment with different data types.

### Pitfalls and Memory Safety

Performing multiplication or division directly on pointers will result in an *error*. Additionally, using float numbers with pointers is generally not meaningful and can lead to unexpected behavior.

Be caution

Accessing memory beyond the allocated bounds, often due toincorrectpointer arithmetic, can lead to serious issues such ascrashesandsecurity vulnerabilities.
