In C++, can you provide a simple string Null Termination Error program and then show how to fix it as well Please and thank you

In C++ fill in the blanks

Write a program in C++ which adds, subtracts, multiplies, divides and performs exponentiation on two specific numbers. The two numbers should be entered by the user. Each output should include a string describing what the numerical output is being displayed. Use the if-else-if ladder so that the user is able to select which mathematical function to perform. Make sure the program has a neat menu for the user to use to select their choice. Also, avoid having the computer perform a division by zero if the user attempts it by outputting a warning message in its place (use an if-else statement). Include your C++ source code as well as the output of your program in your submission

Write a function in C++ that accepts a student’s final exam grade (worth 40 points) and number of completed projects (each worth 10 points) and returns the calculated final grade (out of 100 points) to the main method.

This assignment will give you practice on basic C programming. You will implement a few Cprograms

Write a program in C++ to help Buddy (the sheepdog) calculate the average age of all his sheep. Theprogram will accept as many ages as Buddy needs to input. The program should help Buddyminimize input errors by error-checking the age for him (everybody knows the maximum age forcartoon sheep is 9 years old). When Buddy’s sheep start to get old, he needs to breed moresheep. So, the code should also let Buddy know if the average age indicates if his sheep are aging,young, or middle-aged based on the chart below:  average Sheep Age      Population is…            <= 3                         Young            4 - 6                    Middle-aged              > 6                          Aging
