Given the following: #define MAX 50 int a[MAX]; What is the maximum valid subscript value for array a?
49
how many numbers can be stored in the array declared below double arr[10][5];
50
How many times is the loop body of the while statement executed? int g = 0;int s = 0;int z = 0;int i = 0;while (i <=5) {scanf("%d", &t);s = s + t;if (t >= 0)g = g + 1;elsez = z + 1;i = i + 1;}
6 times

Compile time error
What will be the output of the following? #include <stdio.h> void main() { struct student { int no; char name[20]; }; struct student s; no = 8; printf("%d", no); }
Compile time error
How would you best describe the purpose of the following code? f = 0; for (i = 1; i < N; ++i) if (a[i] >= a[f]) f = i;
Determine the subscript of the last occurrence of the largest of the first N components of array a.
Consider the following code fragment: char str[10]; scanf("%s", str); What will happen if scanf encounters the string "vivaciously" when scanning a value for str?
Function scanf will store the entire string "vivaciously", even though there is insufficient space in str. The string will overflow str.
How many times will the following loop iterate? int k =1; while (k<=5) { printf("%d", k); }
Infinite
What does the following C function do? int fun(const char *string) { char blank = ' '; int k; int looking = 1; k = strlen(string); while (k >= 0 && looking) { if (string[k] == blank) --k; else looking = 0; } if (looking) return (-1); else return (k); }
It finds the subscript of the last nonblank character in string.
Suppose a program contains the code for (i = 1; i < = 10; i++) { n[i] = 1; }
It is initializing successive 10 elements of an array.
Suppose a program contains the code for (i = 1; i < = 10; i++) { n[i] = 1; }
It is initializing successive elements of an array.
How many times will the following loop iterate? int j = 1; while (j>5) { printf("%d", j); }
No iterations

What value is returned by function result? int result(const int a[], int n) { int i, r; r = 0; for (i = 1; i < n; ++i) if (a[i] > a[r]) r = i; return (r); }
The subscript of the largest of the first n elements of array a.
Which of the following statement is true about the statement below? int score [5] = {83, 92, 78, 94, 71};

ans1ans2ans1ans2
What will be the output of this program fragment? char u, v, temp;u = 'a';v = 'b'; while ( v != 'a' ) { temp = u; u = v; v = temp; } printf ("%c %c", u, v);
ba
The function prototype double mySqrt(int x);
defines a function called mySqrt which takes an integer as an argu-ment and returns a double
Which of the following code segments does not contain any errors?
double triple(float n) {return (3 * n);}

five(6.2, &p, &n);
Which loop is specifically designed to initialize, test, and increment a counter variable?
for loop
Two arrays with the same number of elements and related data are called _______ arrays.
identical
What will be the output of this program fragment? int i; for(i = 0 ; i=1 ; ++i){ printf("ans1"); printf("ans2"); }
