Please i need a help in bash script (linux) ,if im allowed just to use nested ifs,  i want to  take numbers from user and each number will execute some statements;  allowed inputs are 20,30,40.                                                        if the inputs entered were different then we should print a message "wrong number" and ask for entering again a number that is allowed. if  the input is 20 then it will execute :  echo "20989" if the input is 30 then it will execute3 :  echo "90999"  if the input is 40 then it will execute :  echo "40909 "

Shell Scripting: Write the output when the input is 40: echo -n "Enter any number:" read n if [ $n -eq 30 ] 11 [ $n -gt 50 ] then echo "1" else echo "2" fi

C++ Also prompt the user for the total amount deposited. Do not accept a value less than zero; display an error message and exit the program if this occurs. If the number of checks entered is greater than zero, prompt the user for the total amount of the checks written. Do not accept a value of zero or less; provide an error message and exit if the user enters invalid data. We will also bring this problem into the 21st century and consider ATM transactions as well. Prompt the user for the number of ATM transactions. Like number of checks written, do not accept a negative number here. If the number of transactions is greater than zero, also prompt for the total amount withdrawn. Do not accept zero or less for that total amount. The first five ATM transactions are free; charge a dime for each subsequent transaction. If the balance after charges and withdrawals are applied but before the deposit is credited is less than the minimum balance of 400.00, charge them the low balance fee. Yes,…
