1. You are working for the census bureau and you need to write a program to count the number ofpeople in each of the following age groups: 0 - 16 (16 included) infant, 16 - 29 young, 29 - 55 middleaged, 55 - 75 old, 75 - and older, really old (intervals closed to the left, open to the right). Report thenumber of people in each age group.2. You are again working for the census bureau and they need some statistics regarding the distributionof ages. Write a program to read in a number of ages. (You do not know upfront how many entriesyou have, so you need to keep track of it.) Compute the average age and the age that occurs mostfrequently (some of the ages might be the same). Ages should be read in as integers, the averageshould be a real number. Calculate the population standard deviation using the formula:2Standard deviation =Σ/n-(Στ/n)

My Solutions > FA2.1.1 Longest Word Write a function named longestword that is use to compare words from the string vector named as word. The user will input the string vector word and the function will return the value of variable longest, the word with the most number of characters (and the first in the list when they have the same length). Sample Output: >>>longestword("Heat","Lakers","Warriors") Warriors Note: The following are the matlab functions that you can use in your script: length=use to return the number of elements in a string vector. strlength=use to return the number of characters in string Function e A Save C Reset I MATLAB Documentation 1 % Use if-elseif-else statement Code to call your function e C Reset 1 word=["cent", "centennial","century"]; 2 longestword(word) 3 word=["love", "care","joy"]; 4 longestword (word) 5

AC that adds two very large integers entered by the user on the keyboard write the program. Very large integers represent standard data types (long int, double, etc.) you cannot collect it using. Reading and adding numbers from the keyboard as a string As you learned the process in elementary school, starting from the units digit, you can add the mutual numbers one by one. you must realize by collecting. The numbers that the user has entered into a different number of digits. In order to have it, your program should work. The output of your program is the example below should be compatible with the program outputs. In the program output, as in the addition operation the numbers and the total should be written one under the other, with the mutual digits aligned.

Jane has opened a new fitness center with charges of 2500 per month so the cost to become a member of a fitness center is as follow : 1.For senior citizens discount is 30 % 2. For young one the discount is 15 % 3. For adult the discount is 20% Write a menu driven program (using structure) that a. Add a new member b. Display the general information on about the fitness center and its charges c. Determine the cost of a new membership d. At any time show the total money made. Use appropriate parameters to pass information on and out of a function.
Because it involves estimating a function's value at a point outside the data's range, this process is known as interpolation.
