QUESTION 3 Consider the following code: int arr[5] = { 5, 12, 13 }; int *ptr = arr; ptr++; *ptr = 27; After this code has been run, what does the array contain? O 5, 12, 13, 27} O {27, 12, 13} O {5, 27, 13} O {5, 27, 12, 13} QUESTION 4 Consider this line of code: A. 12 char *str = "Alphabet soup"; Match the following questions with their answers v How many characters are in this string? How many bytes are required to hold this string in memory? What function will tell us how many characters are in the string? Where is this string stored in memory? B. 100 C. 14 D. 12 E. strlen F. Stack memory G. Global memory QUESTION 5 Consider the following code: char buff[100]; printf ("Enter word: "); scanf("%s", buff); We want to test if the user entered the word Hello. This of the following code fragments is correct? O if (buff.equals("Hello")) { ... } O if (buff == "Hello") { ... } if (strcmp(buff, "Hello")) { ... } O if (strcmp(buff, "Hello") == 0) { ... } O if (buff = "Hello") { ... } QUESTION 6 Consider the following code: struct pair { int x, y; }; We want to declare z to be a pair, and to set z's x value to 1 and y value to 2. Which of the following code fragments will correctly do this? Check all that apply struct pair z = {1, 2}; O struct pair z; Z.X = 1; z.y = 2; Ostruct pair z; Z->X = 1; Z->y = 2; pair z(x = 1, y = 2)
