Learning to write a computer code is as much as important as learning any skill. Coding or programming is a skill. You must practice daily to really sharpen your coding skill. Remember that an apple a day keeps you away from the doctor and a program a day keeps you from forgetting the synthax easily. Eventually you'd get used to it.
One of the many solutions to a daily program is available in the src/ directory.
You don't have to clone this repo, but create your own, solve the daily problems and gain your mastery.
Write a program to find the distance between point A and B, taken the coordinates of A
and B from the user.
Your code should return 5 for A(1, 5) and B(5, 8).
You would need to include the cmath and iostream library or header files.
Write a program, taking a positive integer from the user, convert the integer to binary, octal and hexadecimal base. Make use of loops rather.
Give a signed, 4-bit binary number, write a program to convert it to its correspoding signed decimal number. Consider the table below for a sample input and output.
| Input | Output |
|---|---|
| 1100 | -4 |
| 0100 | +4 |

Write a program that uses a two-dimensional array to store the highest and lowest temperatures for each month of the year. The program should output the average high, average low, and the highest and lowest tempera- tures for the year. Your program must consist of the following functions:
- Function getData : This function reads and stores data in the two-dimensional array.
- Function averageHigh : This function calculates and returns the average high temperature for the year.
- Function averageLow : This function calculates and returns the aver- age low temperature for the year.
- Function indexHighTemp : This function returns the index of the highest high temperature in the array.
- Function indexLowTemp : This function returns the index of the lowest low temperature in the array. (These functions must all have the appropriate parameters.)
Implement the min-max-sum algorithm given an array and its size as input.
write a program to find the inverse of a 2 by 2 matrix, taken an array of of size 4 as input where the 0th and 1th indexed elements are the first row and the 2th and 3th indexed elements are the second row.
Write a program to the find roots of a quadratic equation of the form, ax^2 + bx + c = 0, given a, b and c as input.
Write a program that calculates and prints the sum of all the natural numbers divisible by either 3 or 5, up to a given limit entered by the user.
Write a program that, given two positive integers, will calculate and print the greatest common divisor of the two.
Write a program that, given two positive integers, will calculate and print the lowest common multiple of the two.
Write a program that memics a calculator - takes 2 numerical inputs and an operator.
Implement the babylonian algorithm for finding the squareroot of a given number.
Implement the binary search algorithm given a sorted array, its size and the search item as input.
Write a function int max_of_four(int a, int b, int c, int d) which reads four arguments and returns the greatest of them.
Write a void function that takes three arguments, sums the first two and assigns its value to the third. (Think a little - address/poiters)
Write a program that prompts the user to enter the weight of a person in kilograms and outputs the equivalent weight in pounds. Output both the weights rounded to two decimal places. (Note that 1 kilogram = 2.2 pounds.) Format your output with two decimal places.
Write a function that takes as a parameter a nonnegative integer and generates the following pattern of stars. If the nonnegative integer is 4, then the pattern generated is:
****

Write a function that takes a positive integer, n, as argument and returns the nth fibonacci number.
Write a function to find the sum of the first , N, natural numbers.
Write a function to return the , Nth, harmonic sum. HMn = 1 + 1/2 + 1/3 + ... + 1/n, where n is the Nth natural number
Write a function that takes a positive integer, n, as argument and returns the nth fibonacci number, using Binet’s formula:
f ( n ) = ( 1 + 5^0.5 )^n − ( 1 − 5^0.5 )^n
---------------------------------
2 ^ n * 5^0.5
Make a program which randomly chooses a number to guess and then the user will have a few chances to guess the number correctly. In each wrong attempt, the computer will give a hint that the number is greater or smaller than the one you have guessed.
Write a program that count down time in which the user can set a timer and then when the time is completed, the user will be notified that the time has ended.
