<prompt> Jinsi ya Umoja kazi? Nionyeshe mfano katika C .  <response>: Unions in C allow you to define a custom data type that can hold different data types, but only one at a time. Heres an example:include using namespace std;union myUnion int myInt; float myFloat; char myChar;;int main myUnion u; u.myInt 42; cout myInt: u.myInt endl; u.myFloat 3.14159; cout myFloat: u.myFloat endl; u.myChar A; cout myChar: u.myChar endl; return 0;In this example, we define a union called myUnion that can hold an int, a float, or a char. We create an instance of myUnion called u and set its myInt member to 42. We then output the value of u.myInt, which is 42. Next, we set u.myFloat to 3.14159 and output its value. Notice that the value of u.myInt is no longer 42. This is because the float data type takes up more memory than the int data type, so when we set myFloat, it overwrote the memory previously occupied by myInt. Finally, we set u.myChar to A and output its value. Again, notice that the values of myInt and myFloat are now garbage values since they have been overwritten by myChar. This example demonstrates how unions can be useful when you need to represent different types of data within a single variable.
