- Q2: (Debugging Code) : As you are learning to program in C, you will often spend a lot of time debugging code and finding errors. It takes a lot of practice to develop this skill. There are many errors in the following program. Find and correct all the errors so that the program compiles and produces the correct output. (Add a new comment on line 1 of the code and list the errors.) Find all the errors challenge * includeGuessing game: Read a number until it's equal to a chosen number (first it can be a hard-coded constant or #define, or you can check rand() later). In case of wrong guessing help the user by printing whether the guessed number is to small or too big. ( in C language)Which aggregating operations are permitted for struct variables but not array variables, and which are prohibited for array variables?Kindly fix the errors in this assignmentI'm getting an error on error: expected ' ' before ' '} else if (grade == 'B') { (I cannot see the error)[ Here is the assignement ] Write an structure that will print a message based on the grade ( A,B,C,D,or F). Do this first using an if statement. Then do it using a switch statement. The grade and message are as follows. • A Excellent Job • B Very Good • C Average • D Need more effort ------- code -------#include <stdio.h> int main() { char grade; printf("please enter your grade (A, B,C,D, or F): "); scanf("%c", &grade); // Using if statement if (grade == 'A'){ printf("Excellent job!\n");{ } else if (grade == 'B') { printf("Very good!\n"); } else if (grade == 'C') { printf("Average. n"); } else if (grade == 'D') { printf("You need more effort.\n"); } else if (grade == 'F') { printf("You need to get some help. \n"); } else { printf("Invalid grade entered.\n"); } //…Complete the function empty which returns true if s1 has a length of 0. You may not use any library functions from . cstrings.cpp #include using namespace std; bool empty(const char* s) { 1 4 5 7 8 }Number guessing Game Write a C program that implements the “guess my number” game. The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1; that creates a random number between 1 and 100 and puts it in the variable r. (Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make…What is error in this codeWhat are some ways you can make code more efficient when using if-else blocks?C++ Code: Oj is a cruel but wise student of his class. Because of his bad habits, one day his math teacher got angry and challenged him to do a few maths.
