Table-5 Exercises

< CS101

For these exercises, write code to count names which meet certain conditions and when the loop is done, print a line like the following to report the count.

count: 23

Optionally, you can print out the names in your loop to see what your code is doing, so long as the "count: 23" is printed last.

The code to produce the above line looks like following, but the real work is in initializing and updating the count variable (or whatever variable you use).

print("count:", count);

The starter code includes the standard count = 0; line to set count to zero before starting.

1. Write code to count and print number of names starting with the letter "L". The last line printed should look like the "count: 23" example above (note: the answer is not 23, that's just a number I made up).

table = new SimpleTable("baby-2010.csv");
count = 0;
for (row: table) {
  // your code here
  
}

2. (Variant of above) Write code to count and print the number of names not starting with the letter "L" in the "count: 23" format. Maybe don't print the names themselves for this one, as there are very many of them.

table = new SimpleTable("baby-2010.csv");
count = 0;
for (row: table) {
  // your code here
  
}

3. Write code to count and print number of girl names starting with "T" in the "count: 23" format.

table = new SimpleTable("baby-2010.csv");
count = 0;
for (row: table) {
  // your code here
  
}

4. Write code to count and print the number of boy names ending with "d" in the "count: 23" format.

table = new SimpleTable("baby-2010.csv");
for (row: table) {
  // your code here
  
}

5. How many names ending in "m" are there with a rank <= 500? Write code to count and print this number in the "count: 23" format.

table = new SimpleTable("baby-2010.csv");
count = 0;
for (row: table) {
  // your code here
  
}
