Step by step
Solved in 3 steps
- 2- In C++ language, every line of code must end with a semicolon. (True or False). 3- It is not possible to change the value of the pointer. (True or False). 4- If the following lines of code have errors, correct them; otherwise, write "no errors." for (int i=2; i<5; i++) { int s=i*2; } cout << S; 5- A function cannot be called from inside another function. (True or False). 6- How to make a function return multiple values? 7- Every class member is by default. (public, private, not public nor private) 8- Create an instance of the following class and call its methods. class Exam{ int grade; public: void seta (int b) (grade=b; } int geta () {return grade; } 9- When the word const is put before the variable definition, what does that mean? 10- How to concatenate two strings in C++ language? C++In which memory segments are the variables in the following code located? int i = 0; void func(char *str) { char *ptr = malloc(sizeof(int)); char buf[1024]; int j; static int y; }Consider the following code: int main() { char *s = strdup("This is a test"); char *d = " "; while (s) { char *token = strsep(&s, d); puts(token); } free(s); return 0;} Which of the following causes an error or segmentation fault? A. free is called on a pointer that was not malloc'ed B. strsep must be called with s instead of &s C. The while loop is an infinite loop D. The string s points to is in read-only memory E. Something else
- Assuming buf is a valid pointer, what is the problem in the code below? What would be an alternate way of implementing this that would avoid the problem? size_t sz = buf->size(); while ( --sz >= 0 ) { /* do something */ }void show_byte(byte_pointer start, int len) { Q2 int i; for(i=0; iThe statement int *p;declares p to be a(n) [l1] . p will store an integer value p will store the address of an integer variable p will store the result of multiplication of two integers p will store the address of a variable of any typeUsing C++ Programming language: Given the following definitions: int num1=1, num2=2; int *ptr1=NULL, *ptr2=NULL; Write the following statements: Assign ptr1 to the address of num1. Assign ptr2 to the address of num2. Using pointer notation, write a statement that compares the values that the pointers "point" to to see which is larger. (There is more than one way to do this. You choose.)int *p; where p is a null pointer when:swap_nums seems to work, but not swap_pointers. Fix it. #include <stdio.h>void swap_nums(int *x, int *y) { int tmp; tmp = *x; *x = *y; *y = tmp; } void swap_pointers(char *x, char *y) { char *tmp; tmp = x; x = y; y = tmp; } int main() { int a,b; char *s1,*s2; a = 3; b=4; swap_nums(&a,&b); printf("a is %d\n", a); printf("b is %d\n", b); s1 = "I should print second"; s2 = "I should print first"; swap_pointers(s1,s2); printf("s1 is %s\n", s1); printf("s2 is %s\n", s2); return 0; }Do the following in the most efficient way possible in C Language: 1. Take an Array of 10 integer values (automatically should be converted to ascending order). 2. Insert Values - Value should be inserted automatically as per the ascending order. If array is {1,7,28,45,67,81} and the user inserts 31; the program should automatically insert at the 3rd index and array size should increase by 1. 3. Delete Values by Range - the user will be asked to two indexes (<sizeofArray) and all values in between those indexed should be deleted. E.g. If array is {1, 7, 28, 45, 67,81} and user enters the indexes 2,4. Then the values 28, 45, 67 should be deleted.Do the following in the most efficient way possible in C Language: 1.
