1) Write high-level and detailed pseudocode for a program that calculates the current balance in a bank account. The program must ask the user for

 

• The starting balance
• The total dollar amount of deposits made
• The total dollar amount of withdrawals made

 

Once the program calculates the current balance, it should be displayed on the screen.

 

 

2. The variable sum starts with the value 0.

       Add 10 to sum.

       Add 15 to sum.

       Add 20 to sum.

       Display the value of sum on the screen.

 

 

 

3.  The variable x starts with the value 0.

       The variable y starts with the value 5.

       Add 1 to x.

       Add 1 to y.

       Add x and y, and store the result in y.

       Display the value in y on the screen.

 

 

4.  The variable j starts with the value 10.

       The variable k starts with the value 2.

       The variable l starts with the value 4.

       Store the value of j times k in j.

       Store the value of k times l in l.

       Add j and l, and store the result in k.

       Display the value in k on the screen.

 

 

 

5. The variable a starts with the value 1.

      The variable b starts with the value 10.

      The variable c starts with the value 100.

      The variable x starts with the value 0.

      Store the value c times 3 in x.

      Add the value of b times 6 to the value already in x.

      Add the value of a times 5 to the value already in x.

      Display the value in x on the screen.
