please do in C++ not python

please post the code, program inputs, program outputs, test plan, and pseudocode write a program to input 4 individual numerical characters. The 4 digits entered must be stored into 4 distinct character variables. After inputting all 4 character variables, your program should display each character, in the order they were entered, one per line. After this, your program should calculate the sum of the digits. Display this sum with an appropriate label. Note that you will need to convert the character digit to a numerical digit prior to adding the values together. If you do not do this, you will end up summing the ASCII values. Next, calculate the numerical value of the characters in reverse. For example, if the characters are entered in this order 1234, ' 1 ' will be stored in a character variable, ' 2 ' will be stored in a character variable, ' 3 ' will be stored in a character variable, and ' 4 ' will be stored in a character variable, then you will calculate the numerical value 4,321 and store it into an integer variable. After the character processing and display, your program will then input one integer value. You should pick the digits off of the integer value and print the value in the ones place, the value in the tens place, the value in the hundreds place, the value in the thousands place, and the value in the ten-thousands place, each on an individual line with appropriate labels
