- You need to write a program in C that will allow a teacher to store, update and view the grades of multiple students. The program should perform the following operations: Add a new student and their grades for different subjects. View the grades of a particular student. Update the grades of a particular student. View the average grades of all students.The program should store the following information for each student: Student name (string) Roll number (integer) Grades for 5 subjects (integers)The program should implement a menu-driven interface for the user to perform the above operations. The program should continue to run until the user selects to exit.Constraints: The student name should not exceed 50 characters. The roll number should be a positive integer and should be unique for each student. The grades should be integers in the range [0, 100].6.use c code to Develop a code that gets two integers from the user and calculates and prints their least common multiplier or LCM. LCM is the smallest number that divides both given integers. Example. lcm (10, 15) = 30, lcm (5,7) = 35 and lcm (12, 24) = 24Hint: we know that lcm(x,y) = xy/gcd(x,y) where gcd is the greatest common divisor (discussed in class). Develop a gcd function in your code, get the two numbers from the user, call your function to calculate their gcd and then use the formula above to calculate and display their lcm GOOD LUCK! Reference This is a list of function prototypes of the C library functions presented in class. You may use any of these functions in your solutions (unless the requirements explicitly indicate otherwise).

- C++ Programming Request a 3-digit integer from the console.Use division and modulo operations to extract each digit in reverse order. For each digit, determine if it is a factor of the original integer. Example Output Enter a 3-digit integer: 543 Is 3 a factor of 543? 1Is 4 a factor of 543? 0Is 5 a factor of 543? 0With C programming and without function and pointer Problem Statement You love binary numbers 0 and 1. Now,You are given a binary string S of size N. Now you need to tell total how many 01 and 10 pair exist in the given string. Note - A binary string is a string which contains only 0 and 1. And you have to consider 01 or 10 as consecutive. Input Format The first line will contain T, the number of test cases. The first line of each test case contains a positive integer N. The second line of each test case contains a string S, consisting only 0 and 1. Constraints 1 <= T <= 100 1 <= N <= 1000 Output Format Print the count of pairs. Sample Input 0 41210101111101061010113100210 Sample Output 0 7 4 1 1in C++: Given a decimal number, your code must convert the decimal number into binary, and insert the three necessary check bits that validate it as being correctly assembled and received. Please display the following results: -1 The Original Decimal Number -2 The Correct Form of the resulting Hamming Code 1: 15 2: 7 3: 12 4: 2 5: 6
- String to integer ATOI (requires use of INT_MAX and INT_MIN): Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of the string) is '-' or '+'. Read this character in if it is either. This determines if the final result is negative or positive respectively. Assume the result is positive if neither is present. Read in next the characters until the next non-digit character or the end of the input is reached. The rest of the string is ignored. Convert these digits into an integer (i.e. "123" -> 123, "0032" -> 32). If no digits were read, then the integer is 0. Change the sign as necessary (from step 2). If the integer is out of the 32-bit signed integer range [-231, 231 - 1], then clamp the integer so that it remains in the range. Specifically, integers less…In the function malloc(), each byte of allocated space is initialized to zero. a) True b) Falsea) What is "Approximation Error" in floating-point representation? Approximation Error - Since in floating point representation we can not represent all real numbers so there occurs an error.It is difficult to represent some decimal numbers in binary form. b) Why is it happening? Floating point Approximation error occur because it uses fixed no. of bits to represent decimal numbers. It is difficult to represent real numbers with the help of fixed bits of binary numbers. Also some decimal numbers are difficult to represent in binary form. c) How can we minimize it? We can minimise it by- 1.Changing radix 2.Adding numbers of different magnitude value. 3.overflow 4. underflow 5.Subtracting numbers of same magnitude value. Dont use answers from other websites please! Please type your answer not picture d) How can the character codes be a solution for this?
- C++ program Write a CPP program to do the following using recursion: 1. Using the current estimated population of 7.7 Billion and an estimated growth rate of 1.06%, compute the estimated year when the population year could exceed over 20 Billion. 2. Display the year (2xxx) and estimated population values for each year as you do this processing. 3. Start with the current year and display the data in ascending order. I am specifying this as it is possible to report this in descending order if the display is done after the recursion. For this assignment, create a method that calls itself recursively, passing the year and current population to itself. You can increase the population by applying * 1.0106 to increase by 1.06%. This method can return void and thus should do all the displays and computations needed. Display the year processed and estimated population value.. The variable for the population should be a double data type. Do not allow the display to be in scientific…6. Find the errors from the following code. a.
