Use C language Exercise 2:Write code for the following functions:A. int strlen(const char "s); [returns string length]B. char* strepy(char *s1, const char *s2); [Copies string s2 into array sl. The value of sl isreturned.]C. char* strcat(char *sl,const char *s2); [Appends string s2 to array sl. The first characterof s2 overwrites the terminating null character of sl. The value of sl is returned.] Useabove function in your program to get and print length of a string, copy strl to str2 andappend str2 at the end of str1. Do not use string.h header file in your programme.

The last character of a string is appended by null and it is represented as \0

: Write code for the following functions: int strlen(const char *s); [returns string length] char* strcpy(char *s1, const char *s2); [Copies string s2 into array s1.

1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.

Sum Difference Given an array of integers, write a program to find the difference between the sum all the even numbers in the array and sum of all odd numbers in the array. You can subtract the sums in whatever order you wish but the function must always return a positive integer. Please complete a function called SumDiff, which takes an argument of an array of numbers and returns an integer. function SumDiff(numbers) {// your code here// returns an integer}Example test case:Input: [1,5,8,2,10,33,36]Output: 17Reasoning: (8 + 2 + 10 + 36) - (1 + 5 + 33) = 17
in c++ In statistics, the mode of a set of values is the value that occurs most often or with the greatest frequency. Write a function that accepts as arguments the following: A) An array of integers B) An integer that indicates the number of elements in the array The function should determine the mode of the array. That is, it should determine which value in the array occurs most often. The mode is the value the function should return. If the array has no mode (none of the values occur more than once), the function should return −1. (Assume the array will always contain nonnegative values.) Demonstrate your pointer prowess by using pointer notation instead of array notation in this function.
Tasks: 1.Write a function myStrLen(char*) which returns the length of the parameter string without using strlen function. 2. Write a program that takes an array large enough to hold a user-defined number of test scores. Once all the scores are entered, the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates the average score. The program should display the sorted list of scores and averages with appropriate headings. 3. Write a program to combine two string by using pointer without using any built-in function of strings.
In C++ language Write a function that takes a 1 Demensional array and an integer n and reutrns the number of times 'n' appears in the array. If 'n' does not appear in the array, return -1.
