Given the C code below, specify the implementation of the function square(), in such a way that the input of the program is a real number inserted by the user and the output of the program must be the square of that number. Do not modify the main function, just specify the implementation of the function square() to fulfil the requiremets. #include int main(){     float x = 0;     printf("Square of the real variable x\n");     printf("Insert x: ");     scanf("%f",&x);        square(&x);     printf("New value of x: %.2f\n",x);     return 0; }

In C++ i need the fill in the functions that will complete this code for the program to work.

1. Write function printGrade in void function to compute and output the course grade. The course score is passed as a parameter to the function printGrade. (The program will take 5 inputs for 5 subjects. And show the grade of each subject. And calculate the CGPA) TTTE Percentage Score Quality Point Renark Letter Grade 8e - 100 75 - 79 70- 74 65- 69 6e- 64 55- 59 se - 54 45 - 49 40 - 44 35 - 39 e. 34 Excellent Extrenely Good Very Good Good Fairly Good Satisfactory Quite Satisfactory Poor 4.00 3.67 3.33 3.00 2.67 2.33 2.e0 1.67 1.33 Very Poor Extremely Poor Fail 1.00 Expected Output: Inputs 1.
