- Question 2: Correct the following if statement below.#include <stdio.h>int main(void){int volt_1=12;if(volt_1 < 10);{printf("This prints inside the if function \n");}printf("This prints outside the if function \n");}A void function requires the use of an lvalue. A. True B. False C. It depends. Thank you!Indicate which operator will be executed first in the following statements. a = 2 * (i + j) % 3; b = 2 * i + j % 3; c = arr[i + j] / i + j; c = arr[i + j] / (i + j);
- Assume the following declarations and initializations (MIN, MAX, num) are made just before each sub-question 1 to 15. What is the output each code?int main() { E(); C(); E(); } void B() {...} void C() {...} void D() {...} void E() { B(); D(); } Which describes the order in which the functions are called when the program is run?Please circle True or False for each of the following statements. C++ The return type void indicates that a function will perform a task but will not return any information upon completion of that task. TRUE FALSE
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)QUESTION 4Write a function named Quotient with 2 Integer parameters (originally from text boxes) and a Double return type. The function should calculate the first parameter divided by the second and return the resultDetermine if the following statements should use permutation or combination Five friends posing for a picture-taking at the park. Arranging six pots of different plants in a row
