The document contains 10 C++ programs demonstrating the use of if-else, switch, loop, and nested loop structures. Each program includes the necessary header files, defines a main function, and demonstrates basic conditional logic and/or iterative logic using the given control structures. The programs cover examples such as calculating electricity bills based on usage, determining grades from marks, finding the day of the week, and more.
