In the program declare a pointer to the structure. Ask the user to enter the values for each structure. Then, using the pointer, print the values of each structure s1 and s2. Don’t access the structure variables directly (i.e. don’t use s1.a, s1.b, etc.

C PROGRAMMING - Edit the Code Below to Use Pointers   Instructions) Edit the code in order to make the user enter the lengths of the sides of the triangle directly into the structure using a structure pointer and the  "->" operator. Then, in a function, calculate the perimeter and area of the triangle. Pass the triangle structure to the function by reference using the structure pointer. Lastly, in the main() function, print the perimeter and area directly from the triangle structure to the console. Use the structure pointer and "->" operator in the call to printf( ). ------------------------------------------------------------------------------------------------------------------------------------------------------ #include <stdio.h>#include <stdlib.h>#include <math.h> struct calculate{    float a, b, c, perimeter, area;}; int main(){    struct calculate tri;        printf("Enter Side Lengths of a Triangle: \n");        scanf("%f\n", &tri.a);…

Use C++ codingNested Structures: Define a structure for Student containing information about name, roll number, address. The Address is itself another structure containing house no., street no., sector no., phase no., city name. Using arrays declare two addresses for the student: one address is for temporary address and second one is for permanent address. Declare one student structure variable and using pointer to this structure variable take input from the user to enter the information about the student.

Declare a student structure that contains : Student's first and last nameStudent IDCreate the following functions: getStudentInfo(void) Declares a single student, uses printf()/scanf() to get inputReturns the single student backprintStudentInfo(student_t *st_ptr) Takes the pointer to a student (to avoid making a copy)Prints out all of the student informationDeclare an array of five studentsUsing a for loop and getStudentInfo() function, get input of all the studentsUsing a for loop and printStudentInfo() function, print all the output of all students.

Please write the code in C language thank you

When you move the pointer too quickly, a phenomena known as submarineing happens when the cursor vanishes.

When you successfully construct an instance of a structure, what do you get exactly?

Game of Hunt in C++ language   Create the 'Game of Hunt'.  The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U#  Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…
