Programming Exercises
1: Write a program that creates an array with 26 elements and stores the 26 lowercase letters in it. Also have it show the array contents.
2: Use nested loops to produce the following pattern:
$ $$ $$$ $$$$ $$$$$
3: Use nested loops to produce the following pattern:
F FE FED FEDC FEDCB FEDCBA
Note: If your system doesn't use ASCII or some other code that encodes letters in numeric order, you can use the following to initialize a character array to the letters of the alphabet: char lets[26] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
Then you can use the array index to select individual letters; for example, lets[0] is 'A', and so on.
4: Have a program request the user to enter an uppercase letter. Use …show more content…
For example, the fourth element of the second array should equal the sum of the first four elements of the first array, and the fifth element of the second array should equal the sum of the first five elements of the first array. (It's possible to do this with nested loops, but by using the fact that the fifth element of the second array equals the fourth element of the second array plus the fifth element of the first array, you can avoid nesting and just use a single loop for this task.) Finally, use loops to display the contents of the two arrays, with the first array displayed on one line and with each element of the second array displayed below the corresponding element of the first array.
14: Write a program that reads in a line of input and then prints the line in reverse order. You can store the input in an array of char; assume that the line is no longer than 255 characters. Recall that you can use scanf() with the %c specifier to read a character at a time from input and that the newline character (\n) is generated when you press the Enter key.
15: Daphne invests $100 at 10% simple interest. (That is, every year, the investment earns an interest equal to 10% of the original investment.) Deirdre invests $100 at 5% interest compounded annually. (That is, interest is 5% of the current balance, including previous addition of interest.) Write a program that finds how many years it takes for the value of Deirdre's investment to exceed the
